After a 5500 mile trip from CA>TX>LA>GA>TX>CA the unit has started locking up on the map screen. I can change volume, and *sometimes* change source, but never skip tracks, or stations.
I only see a frozen map screen, and that is it.
In order to get ot back to work. I shut off the car for 30 seconds, and turn it back on. This sucks when you get in the car for a morning commute and while in gridlock, the unit crashes.
