[QUOTE="JerryD, post: 433345, member: 17662"] Okay, in looking at the back of the HU, the white plug with the two wires are your video signal and shield. The red wire at that end should NOT be hooked up if you have the power from the camera going to the white/grey. The instructions say to hook it up only because they are generic instructions. You are powering it from the rev circuit. Tape off that bare red wire at the head unit and be sure to disconnect it at the other end. The power is coming from the white/grey wire. You can verify the camera is working and positioned correctly by plugging the camera video in to something that takes video in. However, you won't have a picture on your headunit until you enable the camera with something like the jScan app and an OBD dongle OR have the dealer enable it (for $100 or so). You didn't mention you had enabled it, so I thought I'd mention it. HTH, Jerry [/QUOTE]
