I recently purchased an in-dash multimedia reciever (Dual XDVD8265), but ran into a problem installing it. Once you remove the factory stereo the rear entertainment system will no longer work, bummer right? My plan was to have the rear screen be a secondary monitor for the in-dash unit. (Basically I wanted play movies from the front, have it also show from the back, and have sound from the speakers) I had to figure out how to power the rear system without the factory headunit. So I pulled down the rear player to find out what color wires were coming and going from it. I matched them with ones coming in and out of the harness behind the headunit. 3 matched, a tan, blue/pink, and a green/black. I narrowed it down to the green/black wire. So I soldered this green/black wire to a switched power source (same one used for the new headunit). Now I can power the rear entertainment system without the factory headunit. Outcome: I can watch a movie from the front and back while listening through the speakers -OR- friends can watch a movie in the back using wireless headphones, while I can listen to music in the front(or watch a different movie) The reason I posted this was because when I tried searching for a solution on this website, all I found was new threads asking for help, but no response.(or it was solved using e-mail and wasnt posted in a forum for everyone else to view) Hope this helped someone else trying to figure out what to do.
