From my understanding, the only thing that can be controlled by the car system is the volume, tone controls, and front/back, left/right balance of the speakers. No display of tunes playing on the NAV screen, and tune changes have to be done on the iPod itself. Plus, to keep the iPod battery charged you have to draw power from the accessory power plug in the center console. In other words, this hookup does not give you full integration. :whistles:
