2014 Cruze 2LT came with MyLink without backup camera. I replaced the original cameraless applique with the GM applique w/ backup camera and camera harness. I also replaced the original trunk lid harness that did not have the wires for the camera in it with a new GM harness with the camera wires in it. Now I have ignition power, reverse power, ground and the data wires going to the camera. I pulled the radio to verify that the data wires are in the harness that connects to the radio, which they were. I talked with GM about needing to enable the video feed in the radio and the reply was that it is all 'plug and play', no programming required. However I still cannot get a video feed on my display when backing up. Anyone out there do this before? What am I missing? Thanks.
