Looks awesome! Great review.
I pick up mine next week (same color).
I also didn't get iDrive and will ask for that cable you mentioned when I pick up the car. It's good to know I can dump my iTunes collection on an old iPod and connect that, I might do that instead of dumping the music onto USB drives. Benefit of USB is I can just keep it in the USB port and the iPod, I would have to hide each time I get out of the car. The benefit of the iPod is that I can use playlists and stream online music.
It would be great to hear from BMW why bluetooth music streaming doesn't come standard.....seems so basic now to have that and makes a huge impact on practicality.
