If you decide to go after market
I dont have one but from what I have read online the Pioneer AVIC-N1 In-Dash DVD Multimedia AV Navigation Receiver "includes Navigation, DVD Video, Multimedia Audio/Video and even Vehicle Dynamics capabilities. The motorized, 6.5" touch screen display puts everything at your fingertips. Entertaining DVD movies, CDs, MP3s and XM Radio are just the beginning; also at your fingertips is a powerful navigation database with information on 12 million locations in the U.S. and Canada" and even "Is rear-view camera-ready, just add the optional ND-BC1 Backup Camera. When in reverse gear, the display will automatically switch to the rear-view camera in full-screen mode, to make backing up easier and safer. The rear-view can also be engaged while driving, to allow you to view a towed boat or vehicle during transport."
