Hi, I have a 2021 2500 LTZ pulling a 27 foot Airstream. Tying to setup the Invisible camera. I have the camera mounted on my trailer.I can get a rear camera view, but the Invisible camera will not move from initialtion, no progress bar shows. I have moved the camera to different places, adjusted the seven input numbers and have driven about 30 miles while towing to try to complete the set up. Any one have this issue? Any solutions out there? Thanks
