Wow, I hope that's not what it is. Still hoping it just needs a reboot.

My screen keeps going back to the welcome screen - like when you first turn the car on.
The latest development is that the GPS doesn't work. When I go to navigation, it's just stuck on the screen saying 'navigation system starting'. The rest of the idrive functions work though...as long as it's not rebooting lol
I did have the GPS problem once before actually, and it was a reboot that fixed that particular problem.

Do you remember how long the service was to replace the 12V?
