I didnt get the nav with it since I have a hand held unit but it plays DVDs and VCDs and its iPod, XM and Sirus ready with a AV plug in the front to plug in an MP3 player as well as a USB plug you hang in the glovebox for a Flash drive. I have a 8 gig on the USB now with music on it. Its also set up for a back up camera, and game ports with plugs to add extra screens as well. Should do everything I need, and its a touch screen to by the way....
