I wired the car, mounted and installed the head unit. Everything worked for about 15 minutes while I played music from various connections and played with the navigation system.
When I went to the Setup key and began choosing settings, I was adjusting some sound file setting for a system noise in one of the apps. As I was scrolling the optional noise file titles, the screen stopped responding. The face buttons work. The capacitive screen does not.
I cycled the car power on/off. No change.
I pulled the harness off the rest of the head unit, waited, then tried again. No change.
