Hello ALL, Is there anyone that can instruct me on how to connect my rosen entertainment system (VCR, 10 Disc DVD Changer, TV Tuner) to my N3. Its in a 2002 GMC Denali. it originally had the bose system with the rosen entertainment package from the factory. I have Replaced the bose system with my N3, my own amps, speakers and subs. I have the output of the N3 brain going to the input of the VCR and I can view the N3 screen and rear screen and hear the sound when playing a DVD. When I play the VCR/DVD changer and put my N3 on 88.7 and hear the sound and view the picture on just the rear screen
