After 11k miles, my screen went not blank, but very very dim when leaving work one day around 5PM.

I could barely make out the screen image but it was there.

Nothing special about the day. not hot or cold.

I stopped the truck and restarted the engine. It worked fine after that.

Based on previous experiences with BMW's that had iDrive, I have run across certain sequences that would cause iDrive to require a restart. i.e. Doing too many things at once while the computer is booting.
