I have a 2001 with nav and dsp stereo. I would like a ipod interface that allows movies to be played through an ipod video to the nav screen as well as playing ipod music. I also want the t.v and rear camera. Any one know how and or if this is possible? Think i'll go with factory tv tuner with additional input. I think this should work. And a "dice" ipod adapter. If I do this will a back up camera still be possible?
