Guys I really need some help I have a 2019 Sierra SLT with the"Trailer View Camera" Package and I have the two Aux ports on top of the 7 pin connector. I purchased the camera today for my 6x12 however whenever I connect the camera it is blank on the screen. Furthermore, I followed the installation instruction closely (not to connect the camera when the truck is running) yet there is nothing simply black blank scree. Is there something I am missing? Also the instruction manual talks about doing a calibration in the trailer app but there is no such a thing. All I have is an icon for the camera in the camera app that has the side mirrors and the trailer camera option but whenever the trailer camera is selected whether with the side mirror or not it just shows blank. PLEASE HELP !!
The only thing that I could think off that does not align with the manual is the 7 way connector. My trailer only has 4 pin and I am using and adapter to plug into the 7 way on my truck.
