So I have a 2016 DD and for the past year and a half I have had issues with my backup camera. Sometimes the screen will be fuzzy, or go completely black. I have had the camera replace 3 times and the head unit replaced once. And every time it would fix it temporarily but eventually it would go out again. So I took it to the dealer today and they decided to check the camera wiring from the camera to the radio and what he found was a shortage in the wiring harness. Now that it’s been replaced, hopefully this will resolve the problem.
