I think Audi's navigation system was designed by the developers of the Sega Genesis. Don't get me wrong, I loved NBA Jam and Mortal Kombat on the Sega, but the new iDrive in the F30 blows that sucker away!
The overall interior experience of the new 3-series is first rate. I parked the F30 next to the E90 at the dealership and went from interior to interior. The updates BMW made are impressive.
