Start the engine, wait for iDrive to fully boot up, past splash screen, etc.
The thumb drive goes into the armrest USB port, not the glove compartment.
After the thumb drive is inserted, wait 20 seconds, let it be recognized. Don't rush it.
Go to settings, hit Update, it'll work.
Well, this didn't seem to work.
I'm going to try it with a few other thumb-drives.
It continues to give an error something like, "No USB stick with update found..."
EDIT: Oh well, that didn't work either. Tried with another drive. The USB ports have been working with music etc. without any issues.
