I was playing around with the nav system in power mode one which means from the off position I hit the power button once without the foot on the brake. 30-40 minutes later the car shuts off. I don't recall reading about a timer where the car would shut off after a certain amount of time. I'm wondering if the battery got too low and since the car was off, the car powered down? I tried turning the car right back on which it did with no problem. Stayed on for a long while as well.
hehe.. well. is that in all cases? or just when it's not in full power mode? i never read the manual.. well.. actualy, i did.. but it was lame.
I find that msgs/people here are a better source of info than the manual at times. As far as I can tell the timer only applies to the ACC mode.
