I have a 2015 Macan S with base audio, I am installing a head unit from, speakers, carplay etc all work, the only thing I cant figure out is that when I go into reverse it detects that I am in reverse but the reverse camera display is black, I am 95% sure it's a camera input setting but I dont see where/what I need to change. I attached pictures with all my wiring, the only thing is that I crimped the RX/TX wires to the two blue wires that are capped which didn't fix the issue.
