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? :dunno:

nobody?
 

anything? anyone?

I had a bunch of electrical "weirdness" with my 530i - including some random error messages, and a fan that was stuck on high even when the car turned off (reset only when I locked the car). All was traced to a loose ground connector, hasn't happened since.

So could be any random thing like that.

+1 except I did not pull over and my sat radio started back playing.

Can't help specifically, but my x3 has had an occasion problem like you described and restarting the car seems to fix it.

BMW actually replaced mine because of it, but the new one does the same thing.

guys...thread was two YEARS old.

--------
Yes it happened with my 2013 X5 two weeks after I bought it.
Then it came back on after I restarted the car.
I blamed it on hot Louisiana weather. It was over 98 degrees outside that day.....
It has not happened since then....

Just reboot it. Hold down the volumn button and eject button at the same time for a few seconds and you won't even have to shut off the car. I have done it while driving with no issues

LOL - Timewarp advice ...:rofl: TOO FUNNY!
