TMC & Mio-C230

There have been quite a few questions asking whether the C230 is TMC capable and  I’ve been answering that, yes, I thought so.   I see Mio Europe is selling the TMC receiver specifically for the Mio C230 now, but note that they are only for Italy and France.   Atleast the question has been officially answered.   What I’m not clear on is whether the TMC button has to be unhiddden, or if it does so automatically once the signal is detected.

RDS/TMC Antenna for C230

    What areas in America support TMC?

    It’s hard to find information, but it sounds like the 1-year subscriptions (1st year sometimes included in price) contracts are with Clear Channel Communications (among others), which has FM stations in most major US cities. I imagine it’s very similiar to the traffic information you see “on the 8s” on the Weather Channel.

    The TMC receiver is a small FM-band traffic receiver that connects in between your car stereo and antenna to provide real-time Traffic Message Channel (TMC) data to compatible GPS navigation products—which then depict and identify problem areas on their moving-map displays.

    Available in a fast-growing number of cities throughout North America and Europe, the TMC data gives prompt, accurate notification of accidents, road construction, police, or emergency action, etc.—so drivers can visually monitor traffic flow and, if necessary, select an alternate route.

    The TMC traffic alerting system works on an FM sideband signal (like Muzak used to) which utilizes RDS (Radio Data Service) technology. Digitized and coded real-time traffic broadcasts are received via a “silent” FM data channel—which means that drivers can still listen to music or news programming on their car radios, without interference from the incoming FM traffic data transmissions. In most areas, depending on the service provider, TMC traffic broadcasts are continuous—there’s no waiting for scheduled traffic news updates or random alerts. You see traffic developments in real-time, as they happen, so you can make the right decision sooner. The system will alert you when a traffic problem is on your route and propose an alternate route to avoid the incident.

    Thanks for the link Mike! That’s a nice summary that seems to be more up-to-date than what I’d located.

    I don’t know if you go back through old stuff.
    I had an error on my Mio screen today telling me my trial TMC subscription was about to end. (Didn’t even know I had a subscription) then said I could purchase one at:

    Of course I couldn’t pull a map down or get very much information, I figured the ClearChannel coverage map would have something.

    Hi Mike,
    All comments are emailed to me, so yes I see them all (once I get a chance to get on the PC).

    I got that message one time too, and unless someone pipes in with a more knowledgable answer, I feel it happened after tweaking the data.zip and may be related to the date of a particular file. You’ll notice that many of the files are dated in 2010 and by making changes, the real date has entered the picture, which may be triggering this message. It shouldn’t really matter, because if you do ever actually subscribe to TMC, I would think that information would override.

    You are right, I changed gps information screen in data.zip when this error popped up, however I have changed it before. The only difference is this time I changed the night time file as well, which I never did before.

    how do i get the lastest map update for my c230 & what is the lastest version

  9. c230 said

    al,

    The version of Tele Atlas maps that you have are probably the latest (and probably the only) officially available, since iGo is no longer working with Mio and they license the maps along with the MioMap software.
