I was laying out a route with the engine off in accessory mode when the nav system locked up. I was entering a way point and the system just kept scrolling through way freeways. Touch screen would not work, radio would not turn on, could not turn the system off. I had been at it for quite a while without the engine running. Maybe the battery voltage dropped to a critical point. Called On star and they connected me to Cadillac but they were no help. Finnally I just left it scolling and when they power shut off on it's own and I went back and restarted the car it was ok.
Anyone have a similar problem or any thoughts on cause?
