Um, BMW did update their Nav system. And as far as I can tell, the updated system does everything that the new Volvo system does in that video, save for Touch screen.
And coming from a car that used a touch-based Nav, I can honestly say it's a step in the wrong direction. You take you eyes off the road far too often trying to "aim" for a part of the screen. The iDrive controller is much more exact, and safer.
