I know this is a very old thread. Was there a fix that worked? My stereo just did this today. Its frozen and says "CHRYSLER" on the screen. I cant turn it on or off. No buttons work and neither does the volume or station dial. It also stays on for some time after i shut the car off. It did turn off for a time while I was driving on its own, but did come back on still in the frozen mode. Any help?

A little back ground: everything was working fine until I pushed the gps button and put in the gps disk to play with.
