I am installing an aftermarket car DVD/GPS system in my 2011 Toyota Sienna. I also purchased an aftermarket back-up camera and installed it. They are both made to fit a 2011 Toyota Sienna. I connected the back-up camera to my back-up lights and ran the video cable to the front of the van to the DVD/GPS system. The instructions say to attach it to the AV port that says "CCD AVIN". I connected it to that but the reverse camera video is not being received. There is also a brown wire that says "reversing detection", but I have no idea as to what to connect this to. Does anybody know?
