I installed a 4200nex in my 08 w/Bose and navi and backup camera but I can't get the camera to display on the screen. How did you guys get the stock backup camera to work?
Not entirely sure what harness you used, but if you used the one from Maestro it comes with a short wiring harness, 1 end has a 3 male rca's and the other is a female box like receiver. Plug the rca end that says backup cam into the avic (think it is the brown plug) and hookup the receiver into the male plug from the truck.
I didnt have a backup cam or navigation on mine, but I am assuming that is what the extra wiring harness is for. Think there is a YouTube video of it too. Let me look for it.
