The new North America map update for Mio C-series models (C220/S, C320, C520 and C720t) is now available! The new maps are available directly from Mio on DVD (due to the large file size). Please call Mio Customer Support at 1-866-646-4477 (Monday~Friday 9:00am~6:00pm CST) for more details. The new map update is designed around a new user interface called Mio More Express (MME).
Just got this announcement today from Mio, but it doesn’t seem to be intended for the C230 and it probably wouldn’t be compatible with the Unlock package based on the iGo software anyways. Those of you that have been requesting map updates might be interested in this anyways, and since it is compatible with the C220, it may work with the C230, but you are on your own should you wish to try it out.
[UPDATE] Here is a link to details on the Map update. It doesn’t seem to be of much use to us Mio C230 owners after all 😦
