Instrumentation Disaster
 This iDrive thing is an abomination.  My minivan radio has more capabilities. The iDrive has a nice color screen, looks cool but essentially does nothing.  Really! Shockingly disfunctional and distracts from the overall driving experience.  It constantly displays a warning that essentially says "DONT LOOK AT THIS WHILE YOUR DRIVING".  If I can't upgrade this thing, I think I'm going to trade it in.  really, really disappointed.
