Screen of my Nav/iDrive suddenly went dead while driving
just motoring along and all of a sudden, the screen when dead. i don't mean "blank" I mean dead. then it rebooted by itself (BMW logo) and eventually came back on, but my sat radio wouldn't play. i pulled over and shut the engine and restarted and it all came back fine. have not had the problem since. anyone have any thoughts on what the heck happened?
