Unlocking the Mio C230

[UPDATE]  Version 3.4  Released Jan. 4, 2008


This is what my unlocked C230 desktop looks like (R1)

As I “kick the tires and explore under the hood” of this great little unit, I’ll be documenting my findings in this blog so that it might help others to decide to take it for a drive on the side roads.

‘Unlocking’ is not the most appropriate word, but that is the most popular term used in Google searches for those wanting to increase the versatility of their Personal Navigation Devices (PNDs).  For the average consumer, it is best that when powered on they go directly into GPS mode “out of the box” – the Mio C230 does one job and does it well!


The Mio C230 is actually a 400 MHz touch-screen computer running MS Windows™ CE Core 5.0 Operating System and MioMap version 3.3  mapping software.   All we are doing by unlocking the C230 is renaming one folder and then adding a few steps to the startup sequence so that we are presented with a psuedo desktop to access and use other legal freeware software that is compatible with Windows CE, just like when you add Adobe Acrobat Reader to your PC at home.


Amida168 has done an outstanding job of tweaking the unlocking endeavors of others for “older” versions of Mio’s C series GPS units and being the first to publish an unlock script (version R1) for owners of the C230, along with a very clear set of instructions and a video that will give you a hint at other things you will be able to do with your GPS unit.

Today, my initial set of tweaks…

  • Used a cleaner background image.   As much as I like the new Honda, icons all over a photo just isn’t right.
  • Not showing an icon for DPMS, which I understand turns off the display while programs continue running.  I guess this could come in handy to conserve battery life while playing a long audio stream.   I’ve kept the shortcut for the Suspend function but used the DPMS icon rather than a “power button” icon, since I mistakenly thought I was turning off the C230 one evening using the icon, rather than the physical power switch and had a very low battery the next morning.
  • Added 3 additional apps to the script folder that prove to function with the C230 (the bottom three icons)
    • GPS Calculator (a simple 4-function calculator)
    • Pocket Notepad (could come in handy for taking paperless notes using the keyboard app, but you will need a stylus pen)
    • and GQviewer for viewing an SD card full of photos.
  • Also, I’m choosing not to show the date because it toggles to the next day 5 hours ahead of me since I am GMT -5.  I’ve also choosen not to use the 24-hour format clock, but instead use the AM/PM format.


I was hoping that the miniUSB port on the C230 had been upgraded to a “extUSB” port which is 11 pins, since Mio eliminated the headphone jack (the C220 has a headphone jack), and if this was true, then this device, which I ordered today,


and currently selling for $7.99 on eBay would have proven to be very useful.  There is a cheaper unit, but I chose not to purchase it since I didn’t think the windshield mount would be usable at the same time, nor would you have access to the SD card slot. 

This would have allowed you to charge the battery while listening to stereo audio or feeding audio to a FM transmitter or bluetooth.   Thanks to Julio, it appears that the Mio uses a regular miniUSB, vs.  the extUSB which looks like… extusb_pin_config.png

As he states in his comment, plugging in a regular miniUSB cable into this port will align with pins A,C,D and E (B isn’t used) so it will act like a regular USB port without audio capabilities.  Since Mio doesn’t use the 11-pin version though, I will probably be reselling the adapter.   Regular USB uses two pins for power (charging, etc) and two pins for data transfer.  

Note: The C230 is capable of hi-speed data transfer as it meets the ver 2.1 USB standard, vs. the C220 which was ver 1.0   <Confirmed on 11/20/2007 that this device isn’t compatible with Mio units.>


Canada maps

Two different version 2007.1 Canada maps are available that work great with a Mio C230 purchased in the United States regardless of whether you unlock it or not and they are covered under the same North American license that you’ve purchased when buying the C230 (Europe and other regions of the world – you gotta buy additional SD disk(s) that come with their own licenses).   If you are using a SD card, go for the large map file, which has many more Points of Interest (POIs) than the smaller version.   Create a MioMap folder on your SD card and within that folder create another folder maps where you’ll save your additional fbl file(s).   Otherwise you’ll have to make room on the flash drive by deleting the California map file or a couple of other states you are unlikely to visit, and should use the smaller file.  Remember you can always copy them back using your MioMap DVD.

http://uploaded.to/?id=la0ztgCanada2007.01 – 070705 – 3M POI yES ]ga m*  
http://uploaded.to/?id=fog23cCanada2007.01 – 070705 – 12M POI EvF

A Canada map probably would have been included with the United States and Puerto Rico maps had there been space on the internal 1GB flash drive (that also includes the WindowsCE™ OS, the MioMap software, and the additional files needed for Text to Speech), as would the 3.5 million POIs that were originally released with the updated maps.   Now there are less than 1 million POIs  included.

There is a big plus to Mio not putting all of the map data on a SD card though – Now you can use the slot for adding more map data, MP3 files, movie files, viewing your camera photos, etc.   And don’t forget this an entry-level PND priced below $200!



After spending hours trying to getting the Taskbar to appear on demand*, I’ve stumbled on a method that seems to work consistently, atleast in conjunction with all of the other tweaks I’ve added to Amida’s R1 build.  It seems that running Windows Explorer from File Manager (you will find it in \Windows\Programs) not only fixes the icon associations in File Manager, but it resolves the “Unable to find taskbar window” that so frequently appeared and voila – a hidden taskbar pops into view.   I tried adding “Windows Explorer.lnk” to “Windows\Startup”, but that doesn’t seem to take.  I believe that the reason my Mio runs so nicely is that rather than running MortScript once from the MioMap folder (as many of the other Mio unlock scripts for other models do) and then calling MortScript to run again (from the Script folder) after a soft reset is causing a problem.  I stumbled on this observation after using a menu approach after the hard reset instead.

Using a stylus at the far right side of the hidden taskbar and selecting “Desktop” and – you’re good to go!   I’ve added a toggle taskbar shortcut to the desktop (underneath the mouse).

Other tweaks so far…

  • The 2007 changes for DST work correctly now for the EST time zone**
  • The default time zone is GMT-5 (EST)**
  • Key clicks and screen tap sounds are automatic
  • File Manager font is Tahoma 7, which works much better on the 3.5″ screen
  • Created a hard reset menu to automatically run AUTOPATCHER or proceed directly into MioMap.


*  When googling for these taskbar issues, use “HHtaskbar” as a search term, as that is the taskbar window that your Mio is often unable to locate.  Mio probably hides the window to put the unit in “Kiosk” mode to insure that the taskbar doesn’t interfere with MioMap.
** Added instructions in the script file so that using my code as an example, you can adapt the script to a time zone other than EST.


SD Card

According to the manual,  the Secure Digital (SD) slot in the Mio C230 also supports SDHC cards, which are the faster Class-6 high capacity cards (4GB and up).  You can get a lot of music, audio books, and videos on a 8GB card!  Speaking of playing media, the Core Pocket Media Player is loaded with features and options that aren’t realized until you click Options\Settings\Select Page and explore.  The current version in this build is TCPMP version 0.72RC1 and it will play flash videos as well.


[UPDATE]  Version 3.3  Released Dec. 28, 2007

I had previously stated that I hadn’t planned on “competing” with Amida regarding the releasing of revisions of his great initial unlock package, but today he has given me the go-ahead and so I will proceed.


Installation procedure

  1. Turn on C230 and connect it to the computer using a 5-pin Mini-B USB 2.0 cable (not included in the package).
  2. C230 will show up as a flash drive in My Computer as Mio Device. Mine is assigned as F drive. I’ll use F drive in the following steps. Substitute it with the actual drive letter of your system.  If you have a SD card in the slot, it shows up as well – in my case as G drive.
  3. Rename the folder F:\MioMap\MioMap to F:\MioMap\MioMap2.
  4. If you are using a SD card, create a MioMap folder and within that folder a maps folder so that the path appears as G:\Storage Card\MioMap\maps.  You will have alot more flexibility if you then choose a map file from F:\MioMap\MioMap2\maps and move it to the maps folder on your SD card.  MioMap will see it after a hard reset as if nothing happened.  Or one that you won’t be using (Puerto Rico perhaps?) can simply be deleted, since it’s easy to explore your MioMap DVD and copy it back later, if needed. 
  5. Download MioC230_NXT_R1.zip from this site.
  6. Extract the files from your download and find the two folders MioMap and Script.
  7. Copy MioMap to F:\MioMap\ and copy Script to F:\ as in the screenshot. 
  8. Disconnect Mio C230 and do a hard reset by sliding the switch on the rear of your C230 to OFF and back to ON again.
  9. Rather than having to find a stylus pen, engaging the brain circuitry to try to remember what program gets clicked on and then locating it using File Manager, you will be presented with two menu options (and Cancel):

Unlocked C230 Desktop which automatically runs AUTOPATCHER, does a soft reset and then presents you with the C230 desktop pictured at the top.  When choosing MioMap from the desktop, you will be able to return to the desktop using Amida’s BananaPC option.

GPS Only (MioMap 3.3) which takes you right into MioMap directly as your unit does automatically as shipped from the factory.  You will not have the BananaPC option of exiting MioMap – if you wish to do so you will need to do a hard reset.

 Cancel, rather than choosing one of the first two actual options.   This will take you into File Manager as Amida’s script does, giving you the flexibility to explore further prior to running any scripts.

Note 1: If you hard reset your unit, you will be presented with the step 9 options once again.

Note 2: If you wish to undo the enhancements and return the Mio C230 back to factory condition:

  1. Turn on C230 and connect it to the computer using a USB cable.
  2. Rename the folder F:\MioMap\MioMap to F:\MioMap\MioMap3 (or delete) and rename the folder F:\MioMap\MioMap2 to F:\MioMap\MioMap
  3. Copy back any map files you may have deleted or moved to your SD card 
  4. Disconnect the cable and hard reset C230 using the switch on the back.

Note 3: Remember, every time you disconnect the USB cable linked to your PC, you will need to do a hard reboot and choose the default menu option that reruns the Autopatcher program.  The time and date will also need to be reset, unless you are going right into MioMap with autosync enabled.   This is why you should use a SD card for adding programs and storing media files once you’re happy with your unlocked Mio setup.

Note 4: Mio has not left too much room available on the Flash Drive, but if you are using a SD card, it is easy to free up some space by either installing programs on the card, or moving a map file or two to \Storage Card\MioMap\maps (explained earlier in this blog).  Puerto Rico is 4MB; California is 66MB as examples.  MioMap will see the files in both locations.  The largest file by far in the Unlock download is the GPS Calculator at 1.6MB and should you find the flash drive getting too close to full, this program could be moved to the SD card Script folder instead.  In this example, the Command line in \My Flash Disk\scripts\gpscalc.ini would need to change

  • from  >>   Command = \My Flash Disk\Script\gpscalc.EXE
  • to      >>   Command = \Storage Card\Script\gpscalc.EXE


Using your unlocked C230

You’ll note that the MioMap icon and the Media Player are larger than the rest.  My reasoning for this is that they will probably be your favorites and you are likely to access these without a stylus.   The other icons starting clockwise from the top left corner…

  • MioTool – hitting the small “ab” box with your stylus will reveal a virtual keyboard for entering data.  To turn the keyboard off again, just hit the icon again.
  • Time – current time 
  • MioUtility – quick access to adjust Backlight, Volume, Screen calibrate, Power, Date/Time and Language.  This is the program that older units like the Mio C220 used to exit from MioMap into, but MioMap 3.3 has been written such that these choices are all available from with the program now.
  • WR-Tooks ResInfo – Quick access to status info on battery, program memory, storage memory, Flash Disk useage, Storage Card useage, tasks and processes currently running, system information and settings.  Most of this information is also available from Control Panel as well.
  • Restart – soft reset button.  This comes in handy when you;re stuck in program like FreeCell_ARM (which works by the way) that don’t have an exit button.
  • Battery – indicates battery status kinda backwards; 10 color-coded bars from right to left
  • Move Any Window – the mouse icon, is used when you anticipate needing to drag windows around or gaining access to the right mouse function by opening this program window beforehand
  • Taskbar toggle – toggles the taskbar on and off in whatever state it is in (hidden or revealed)
  • Suspend – suspends the C230 in sleep mode, using some power though – so don’t use this in place of the actual orange power button
  • GQ Photo Viewer – GQ is easier to use for viewing multiple photos than media player, and it has a zoom function
  • pNotepad – viewing txt files and for creating quick txt files with the virtual keyboard
  • GPS calculator – a simple 4-function calculator that is large enough to use without a stylus
  • FileManCE2 – Two-pane File Manager application alternative to Windows Explorer
  • MioMap 3.3 – a scripted shortcut to the original program that came with your Mio C230 along with BananaPC, which has three small icon squares that each act differently depending on whether they are tapped or held down.  Remember about where they appear while MioMap loads up as they hide themselves after a few seconds.  The first icon is an X, which if tapped will close MioMap and soft reset.  If held down it will present you with several options, including switching to other programs running in the background.  The second icon puts your currently program in full-screen mode, which doesn’t apply here, because MioMap already runs in full-screen mode exclusively.  The third icon, if tapped toggles the mute function and if held down – presents you with a volume control panel.   Amida’s primary purpose for this program was to serve as an exit door back to the desktop to avoid using the hard reset option.  MioMap version 3.2 had an exit button built in to the home window and we all wish they’d left it there.
  • TCPMP Media Player – described earlier in this blog.  Ok, you want to play a music playlist or an audiobook while using the navigation functions of your GPS?   That will be tomorrows blog. 


Playing music while navigating 

Yes, it works!

  1. Bring up the taskbar in your desktop (discussed earlier) either hidden or exposed
  2. Click Media Player icon and start up your music (or you can start it later if you wish)
  3. Tap the far right area of the taskbar and select Desktop
  4. Click on MioMap icon and observe the location of the BananaPC icons
  5. By tapping and holding down the X icon, you’ll be able to select TCPMP Media Player (or any other running app) and bounce back and forth.

The audio settings for MioMap are independent of your other programs, so if you hit the mute icon in MioMap so that you don’t get 15 reminders that you are approaching your exit, the music plays on!       Life is great!

I’m finding quite a few programs that I’d like to try out, like GPSimply (straight-line GPS Navigation, as in boating and flying) that installs via .cab file.  My experience is that the C230 doesn’t have  WCELOAD.EXE loaded that is needed to process the .cab file though, so that is the next challenge. I have come up with the registry change needed to switch the USB connection between the PC and the Mio C230 from Mass Storage Class to Serial, which in theory should prevent USBconnect from grabbing the port and allow ActiveSync to instead govern the connection.   Haven’t tried it yet though: #RegWriteString (“HKLM” , “Drivers\USB\FunctionDrivers” , “DefaultClientDriver” , “Serial_Class”)  Can anyone offer their experience in finding a solution?  First thing to try – locating a copy of WCELOAD.EXE and hope all the needed drivers are already present.


Back-Up Camera Monitor

An idea I had last night – Wouldn’t it be great if the GPS could also serve as a color monitor for a rear license plate camera?  After all, you don’t need the GPS function when you are backing up and think how convenient it would be when hitching up to a trailer, not to mention making sure there are no unseen children or obstacles before proceeding to back-up.   Anyways, I found WindowsCE USB 2 video drivers that might have served nicely, but it turns out the mini USB port is a function port only, not the host port needed to attach USB devices.

Now for those GPS units that have Bluetooth built in…


Saving your routes

Normally you don’t need to save a route on your Mio, since you can just create a POI for the destination and regenerate the route dynamically when you want to go there.   If you want to see where you actually drove along the way, you can record a track log.   However, there could be times when you have created a more complex route with multiple waypoints, and you want to save it.   This could be because:
– you imported the route as a set of waypoints from an online route planning site, and you don’t want to lose the effort of setting it up on the Mio
– you set up a complex route for a destination that you don’t go to very often, perhaps in a different city from where you live, and you want to save it for future re-use
– you want to share your route with another Mio user

In that case all you need to know is that the current route is stored in the file “route.dat”.   Using File Manager, this file can be found at \My Documents\MioMap\  and you can copy it over to your Storage Card so that you  can save the route by saving the file with another name like “route_to_vacation.dat”.   Just copy the saved file back to “route.dat” to restore the route.

Backup / Restore

When you back up your Mio (saves your POIs, favorites, Recent Cities and other History lists as well as your preferences within the various settings menus) within MioMap 3.3, it saves the data as iGo_backup.db in the root of your SD card so that you are able to restore your settings.  You might be interested to know that iGo software is the basis for MioMap, so if you find your Mio C230 manual lacking, you might find answers your looking for here.  Even though there are differences in both the software and hardware, there are a lot of good extras in this manual – for instance, when in fly-over mode, by pressing the tilt down button, you are supposed to be able increase the speed of the flyover considerably.   I cannot veify as I changed a setting so that flyover is always fast.

Track Logs

If you enable Track Logs, you will find that they are stored at \My Flash Disk\MioMap\MioMap2\iGo.db and there are programs to convert this data.   You can also export the track log into a gpx file directly, however on the Mio C230, the export button to .gpx file is missing, but can be restored by removing the word “hide” from \My Flash Disk\MioMap\MioMap2\data.zip\mio\320_240\ui\tracking_320_240.ui and zipping the file back up.   When it came to zipping the file back up I choose “best” compression but I’m not sure if really matters.  The exported track logs are stored in \Storage Card\tracks.   You will find more here.

Working on my next release

Along with the improved desktop appearance of Amida’s R2 package , I’m incorporating more reg tweaks for my next release that so far looks like this…


Looks like Amida had trouble getting the time display to behave in R2 so he spec’d a thin-weight font that’s a little harder to read.  This is because he’s calling out its location from the left edge, rather from the right edge.  By changing the [time] section in main.ini using a -X, you specify the distance from the right edge instead. 

x = -3                                   << right aligns the display
y = 18
Color = FFFFFF
Format = h’:’mm’:’ss tt     << gets rid of leading zero
Size = 20
Weight = 700                     << strong weight font can now be used

For an english translation of the online manual to learn more.  The new SystemInformation he’s incorporated works so much easier and has a much improved battery display built in.   I’m finding the unlocks to be very stable and reliable thus far with the exception of Amida’s R2 execution of  \MioMap\MioMap\Startup after a hard reset vs. my menu approach.

Any comments or wishes thus far?

    Do you know how to get the taskbar to work? I already load it at the startup. However, it works intermittently. I am hoping to use it consistently.

    Not, it´s not a extUSB port. I owned (and actually own one HTC Touch) which have the extUSB port and both phones and phone adaptor (as the one you posted) didn´t fit in the C230 port, which is actually a standard mini USB port. The extUSB is a little different, but compatible with miniUSB cables and phones. The inverse is not true.


  4. c230 said

    I appreciate the feedback, Julio. When I peer into the Mio connector, I see contacts on top of the 5 connector holes, unless those are the same 5 tracks. Looks like my theory got blown-up, but I’ll try anyways when it comes in the mail before reselling on eBay.

  5. Jason said

    I know you said you want to work with the author, but is there any chance I can get your build?

  6. c230 said

    Yes, but first I’ll see if amida might package it as R2.

  7. Jason said

    I see you have posted your version, but no link to the ZIP file?

  8. c230 said

    The download is now available.

    Did you have any trick to have the speed limit function to work with the c230 ?

    November 16, 2007 @ 4:14 am

    I’m not aware that it doesn’t work, but I’m not sure that speed limit data is part of the USA maps. I recall reading somewhere that this data was only part of European maps.

  10. Willis said

    Great info here. Appreciate being able to unlock my c230. Thanks to all that have contributed here. Couple of questions. Where are the POI’s located? Can I import a large set of my own? If so what format are they in. Also was wondering where the track logs are located? I appreciate any help you might offer and plese excuse my ignorance.

  11. c230 said

    I don’t have any experience with either of these areas yet, but it looks like POIs are stored at \Flash drive\MioMap\MioMap2\POI and Track Logs are stored at \My Documents\MioMap. Perhaps someone else will chime in.

  12. Tophaholic said

    Hi!!…Thanks for all the hard work you have put into this effort. I especially like the 3 options available in step 9 of your instructions. That would be quite useful instead of looking for a stylus to click on the autopatcher.exe.

    I am not able to access the download link. can you put the files on some other sites like megaupload. Thanks again!!

  13. c230 said

    You’re welcome. I’m only able to do it because so many before me have shared their work through GpsPasSion. Regarding the menu in step 9, I agree that it works out so well, I’m keeping it in my next release, even though Amida’s hard reset screen looks so nice.

    It seems the whole MediaFire site is having problems right now. If it turns out not to be just temporary, yes I’ll check out your suggested site.

  14. Locked Maps said

    I’m very impressed!!!
    You have made a magnificent work,and the unlocking is working great.
    I have one probelm,which u might have a solution.
    I bought the device in the USA,and got the US maps,however I need the local maps of my country,and I was able to do it,only with original SD(which cost more than MIO c230 itself!!!!).

    Does anyone have an idea how to unlock the maps ?
    The map appears with lock icon,and the MIO said – “map files are locked”

    Please anyone,if u can help.



  15. c230 said

    This blog is not about unlocking maps (or any other pay-to-own software) other than by purchasing the appropriate license, but I’m glad you’re otherwise pleased with the C230 unlock.

  16. Bob said

    Thank you for your good work – and please continue exploring and giving us newbies more tips! I expect to receive my Mio next week, my first GPS unit, though I have used MS Trips & Streets w/ a Holux on my laptop.

  17. timrude said

    Any idea when you’ll be ready to make your next release available for download? I’ve tried both of Amida’s releases as well as your first one. No disrespect to Amida but I like yours better. The icons in Amida’s R2 release are hard to identify on sight, and I had some issues with having to do hard resets after connecting and disconnecting the USB cable to the computer. Plus I never could get the taskbar to display in his R2.

  18. c230 said

    I’ll try for tomorrow, even though I have so many other things I wanted to try to get into my release. There’s always R3…

    Thanks for the feedback; I feel the same way but some might say mine has quirks too. He’s advanced the desktop so nicely that I just wanted to build on it. I thought I was onto a good fix for his version, but it wasn’t repeatable.

    When my ShowTaskbar shortcut doesn’t work, I just hit the Windows Explorer icon to resolve, however after the first time after a reset, it sometimes goes into the orange screen with a minimized taskbar rather than engaging Windows Explorer. By clicking the far right side of the taskbar and clicking Desktop – all is well. Everything is consistently reliable and repeatable from that point on, atleast until the next reset.

    By the way, you should always do a hard reset after disconnecting the USB cable. You have to remember this a psuedo desktop that has been interupted with the USBconnect program, not a Windows desktop. If you have a simple file transfer to do, it is much easier to put your SD card into a card reader, transfer the file to it, and then insert the card into the Mio with the power on so that you can copy and paste.

    I released version 2 this morning. ENJOY!


  20. Rob said

    I just purchased a C230 and don’t see any Canada maps on the DVD that comes with it. Are there supposed to be Canada maps? It is mio map v3.3

  21. Rob said

    I bought the C230 today. On the DVD I don’t see any Canada Maps. I live in the USA. Do I have to buy them, using mio map v3.3?

  22. c230 said

    My understanding is that you don’t have to buy Canada as the license you purchased for the USA maps covers Puerto Rico and Canada as well. I agree they could have been added to the DVD as a bonus, but it is meant more for restoring rather than as a resource and probably would have lead to too many questions as to why won’t everything fit.

    It was a little harder to find a link to the files with Google today, but I did and added them to this blog. Enjoy!

  23. robb1 said

    Thank you very much c230 for adding the Canada Maps! As a newbie, I have many things to learn. This blog is a GREAT resource!


  24. Roddey said

    Thanks, It works. The only thing I see is that when in screen capture and I click menu it takes me to a screen I cant get out of without hard reset(I am probably just missing something). Also this is a dumby question but I have never used a PDA. When I open up the game I cant figure out how to close it when I am done besides just minimizing it to the taskbar by clicking on the desktop.. How do I close it?
    You all done a fine job. Thanks for your entertainment. I Like to play with tech stuff. This will keep me away from a garmin for shur. Bye all!!

  25. Roddey said

    I also notice that when the taskbar is showing and I click on the icon on the far right of the taskbar and click “MainShell” then click “Miotool” it will lock up and need a Hard boot.
    I also was wondering if there was a way to stop it from recalibrating the curser every time I need to Hard boot the GPS and use existing settings instead. It ask you if you want to use existing settings after it makes you recalibrate the curser and wait 30 seconds. Thats strange the way Mio set that up. . If it is off it can be recalculated under the settings icon.
    Thanks everyone and cheers to you.

  26. Roddey said

    It would also be nice if the BananaPc icons did not disapear and stayed in view. There small and I dont think would interfere with the operation of the gps. Well maybe if BananaPc had an option to stay on top or autohide. OK OK Now I am done(for now)cheers!!
    Except maybe if we could find the missing .dll files and make windows more versatile.

  27. c230 said


    Yes, don’t click on mainshell.

    I’ve discovered that if you bring up a mimimized “hidden” taskbar first, then you’ll note that programs display their own toolbar that give you the options you are looking for. Other ways of getting out include using the keyboard to hit escape or return, use the soft reset icon, hitting the info icon and killing the task of the problem program, etc.

    I agree with your additional comments. It would be nice to get rid of the calibrate operation after each hard reset. Thinking out loud, if it were way off though, you wouldn’t be able to get to the pages needed to recalibrate.

    As to the BananaPC icons staying on top, I don’t think that option is currently available, but efforts are underway to modify the MioMap skin enough so that the exit button is restored as it was in MioMap 3.2, thereby eliminating the need for BananaPC.

    Is there anyway to connect/use headphones on the device? Browse web? Great Job on the work done! Thanks.

    As far as using headphones, not that I’m aware of Al. I guess Mio had to take something out of their entry-level unit.

    I’ve read that an SDIO card might work for wireless connectivity, and if it does, then we just need to get IE working to browse internet.

    Correct there is no calibrate option in Miomap. This would need to be added by Mio maybe version 3.4 to version 30.4(or never) 🙂 as an option in there Miomap settings pages.

  31. Roddey said

    Anybody crack open the case yet? I would but I want to wait untill the warrenty is up. I want to see about adding a new battery. Also didnt the 220 have a headphone jack? Tear out the antenna jack and replace it with a headphone jack(maybe).

    Just planting seeds of thought

  32. c230 said

    Actually there is a calibrate screen in MioUtility which I’ll bet used to be the start screen in the factory C220. So, in theory, the mandatory calibrate screens could be removed from the startup as long as there was an easy method of getting to the utility in a C230 that was in need of calibration.

  33. roddey said

    Crap, my mio just bricked. The touch screen quit working. So now it just goes to the calibrate screen and I cant do anything. Luckily I just bought it about a week ago and can return it. I think I will buy the extended warrenty this time.

  34. c230 said

    Roddey, I hope you didn’t actually try changing the startup processes. Unlocking the C230 is one thing, but I don’t feel we should really undo Mio’s software which I think is VERY stable. I had a Nextar unit for a couple of days and the thing kept crashing, so back it went. Hopefully, you can restore your unit and get it going again.

  35. Roddey said

    Nope didnt change a thing. I am a follower not a leader.
    But now that you mention it, what file is the startup file in Wince? Does it have a msconfig like in Big Daddy Windows?

  36. Roddey said

    By the way, the startup is OK. Since the touchscreen is not working,it views OK but is not accepting any taps(input). I cant get past the calibration screen.Cheers!!

  37. roddey said

    Well I got another C230. I just learned a new trick. I found out that if I plug in the usb cable while the unit is off then hit the power button I can still use it while its plugged into the computer to charge the batteries. I was about ready to buy a ac to dc cigarette lighter adapter. Great.

    I cracked it open. You only need to remove the 2 screws on the bottom. There is no screw underneath the stickers although it feels like there is. After the screws are off you have to try to expand the case in order for the cover to pop off.

    I already closed it so I don’t remember the battery type, but it sits right on top with connector – should be no problem to replace. The charger chip is next to the battery connector (don’t remember the part number), so as long as it will support the new battery size, it should be no problem…

    As far as a headphone jack, there is no need to remove the antenna jack because there is actually plenty of space in the case. The only problem is that the speaker is MONO and it looks like the preamp circuitry is MONO only, so the only easy hookup would be for mono headphones.

    I tried getting the spec sheet for the samsung processor but samsung does not publish this on their web site. The processor supports AC97 so for headphones one could probably bypass the preamp section and connect directly to the CPU if it will support enough power for the headphones. No way to tell that or what the pinout is without the cpu spec sheet. Would have to contact a distributor to get it, I guess.

    Thanks for reporting your findings PAG. The C220 has a 1200mAh battery and I believe the C230 has a 800mAh battery (if I remember correctly) so I’d be inclined to put the more commonly available C220 replacement battery ($24) in its place if it would fit. Personally, I think if a headphone jack was that important to me, I’d just opt to upgrade to a higher end model that also has bluetooth.

    Speaking of audio, for those that have asked how to get more volume out of MioMap, start an audio stream in TCPMP and go to Options/Audio/Preamp increase. You’ll be amazed at what the unit will pump out, but don’t blow out the little speaker.

  40. roddey said

    Thanks,pag. I could see going ahead and adding a headphone jack for listining to audiobooks through a external speaker used for cb radio….

  41. roddey said

    An amplified external mono cb speaker!!

  42. roddey said

    I know a lot of post by me, but another option is to hook an external fm transmitter like the one form ccrane. It has a variable resistor option that is nice(trans. power option).. Since it is mono I think a splitter would be required. Here is the device—http://www.amazon.com/o/ASIN/B0000E6I1N/105-4151792-9008462?SubscriptionId=0EV0BP902FTD9TZ4RN82 This is a suggestion for audiobooks or MP3’s that would be better than any of the pre-installed gps transmitters.

    Here is a ebay seller that sales igo maps for the USA. Check with the seller but it might be a way of adding more POI to your C230 as long as it is used with a SD card(2gb SD card). Another option is to use only the state maps you need in your gps and swap them in and out as you need them. It says it is licensed. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=330193891143&_trksid=p3907.m32&_trkparms=tab%3DWatchinghttp://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=330193891143&_trksid=p3907.m32&_trkparms=tab%3DWatchinghttp://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=330193891143&_trksid=p3907.m32&_trkparms=tab%3DWatching

  44. roddey said

    Please check with the seller on ebay to make shure the USA maps will work in your Mio. If the USA maps do work, I think the rest of the world wont work with the c230 as it only allows USA maps on it and I read somewhere that it is verified in hardware.

  45. rahjer said

    This shell looks fantastic. Will it run on the c310x?

  46. c230 said

    If that is a newer 320 X 240 unit, perhaps it will. Personally, I favor R2 though (vs R1).

    Looking for a way to speed up the FLYOVER on my C230./… I think I saw it someplace before but cant find it now.

  48. c230 said

    Hook it up to your pc with power on and change slowsim=1 to slowsim=0 in sys.txt file.

  49. Dana Hartsock said

    MioC230_NXT_R2.zip looks like a nice piece of work. I have had a C230 for about a week. Prior to this I have been using a old Garmin 12.

    At the moment the only additional functionality I think I want is Fast FlyOver and Route Management. So… is MioC230_NXT_R2.zip overkill for my modest requirements? If I understand correctly this hack adds MP3 and other stuff.


  50. c230 said

    Hi Dana,

    Route Management is in R3, not R2 and no the unlock isn’t overkill for that revision. The unlock is required since you are not using modified skins that allow you to exit MioMap. The unlock is overkill though if you just want the fast flyover feature.

    Thank you, I’m glad you like the results. I just downloaded a 96 minute podcast to listen to, so you never know when you might be glad you’ll be able to the same, unless you already have an iPod.

    Is there a way to calculate a route between two remote locations? I know this works if the GPS signal isn’t locked on, but once it is the route calculation always includes my current location and I can’t find any way around that.

    It would great if there was an ON/OFF switch for GPS lock to allow previewing remote routes.

    Thanks in advance. 😉

  53. c230 said

    Actually, yes there is. Although I haven’t tried it, the bottom selection on the General Settings page is Off-Route Recalculation. Switch this from Automatic to Disabled. This doesn’t actually turn off the GPS receiver, but it should keep the C230 from messing up your Route planning. This presents another advantage to my Route Management menu starting with Rev 3 Unlock downloads; you can develop those routes and save them.

    When I set up my example route from Boston to Cape Cod, I think the first leg was from my present location to the intended start point. Just keep setting your route up and when you’re finished, remove the first segment using the second button on the bottom of the Edit Route screen. It seems that once you’re in the Edit Route screens /Fit to screen/ etc., that the GPS doesn’t recalculate from your present position. It’s when you are in Map or Cockpit where that happens. With my Route Management Menu, you just exit and Save your Route for future viewing or navigating.

    Thank you, thank you. Excellent tips, very useful, and it works perfectly.

    I tried the fast fly-over change on my locked MIO and the voice guidance disappears. Is this a downside when using a locked device?
    My device is only one day old so I would prefer to wait several months before I try your hack. Thanks for the link to the Canada maps, I did install them.

  56. c230 said

    Yes, the two go together. Another plus to having an easy menu selection to toggle fast flyover. I will add the following to the Fast Flyover section:

    iGo calls the two modes: Lifelike simulation mode which runs at real-time speed-limit speeds and includes voice instructions – mainly used to demonstrating the software and to become familiar with it’s routing functioning. Fast-flyover mode runs at 10X the speed-limit rate and voice instructions are not played, but it is much more useful for reviewing a planned route..

    what about the c220? our europe maps??? please e-mail me!… tnx.. an excelent job and great blog!

  58. Ernst Walther said

    Do you know whether the battery can be replaced to achieve a longer running time? Thank you for your excellent support.

  59. c230 said


    Yes, it can be replaced with a larger capacity battery, but I don’t know any specifics yet. You’ll see comments in my blog that concur, but no model # batteries have been reported yet. (the extra room in the housing allows for a increase in the thickness of the battery, not the height and width)
