Had the D3 in my other truck and then had it installed in my 08 Avalanche. Since I had it put in my new truck for some reason the gps arrow is not following along with the direction im going. It either moves backward or goes sideways on the trail. Any idea why this is happening. Any help would be appreciated. Thanks

I have the D3 in my GMC Sierra and I have 2 headrest screens for my back passengers. Is it possible to play a dvd on the D3 for my rear passengers with sound on headphones and listen to my ipod up front? Thanks

I have the D3 in my truck and installed headrest screens. Video from the ipod does work. The way I did mine is I got a 4 way video splitter to feed signal to the rear monitors
