Much improved Navigation Dock Screen with 10 customizable slots for apps on 2 home screens. Music can play while Navigation is on, which was one of my pet peeves before. The 1/8" audio out comes from the supplied USB cable, not the headphone jack, which will save wear & tear on the jack. Finally, the dock accommodates gel-like protectors (like the body glove) without modification, which shows that Motorola has listened to owners' feedback.
