In accessory mode the car will turn off within 10 minutes. I can’t find the thread but somebody tried to do a nav map update with their car in run mode. The nav map update procedure says to leave it running in Park and that it can take up to 50 minutes. They didn’t want to leave their car running that long. As I recall they said the car stayed on until the battery voltage dropped to a certain voltage and then the car turned off but there was still enough power to start it. I updated my nav map with a battery tender connected to avoid that problem.
