This recent Thanksgiving weekend we were using navigation and decided to take a detour. We knew where we were going, so paused navigation until we were ready to continue to our original destination.
We had been out of the car for about an hour and a half, and when we got back in and tried to resume navigation, we found that the touch screen was totally unresponsive. The physical buttons like Nav and Map and Radio would change the displayed information, but in any mode the touchscreen was completely frozen and unresponsive. We tried stopping and restarting the car, turning the radio off and on, and a couple of other things, but it stayed frozen and unresponsive.
It stayed that way for the duration of our drive (about an hour and a half), and the screen was very warm (almost hot) to the touch.
We stopped for dinner, and after about 45 minutes we came back out and when we started the car, the touchscreen was working again.
Any ideas what happened, how to avoid it, and what to do to get functionality back if it happens again?
