Hi all i know I'm new here but i could use the help of a upgrade specialist if you will lol .radio module is from a 2023 screen I'm not going to lie not 100% sure every single feature works perfectly but no matter what i do blue rear camera !!! I'm a bit older and not super familiar with alfa odb but I'm trying my best i don't wanna mess up anything . i plug my 8.4 radio non nav uc4 camera works no problem every time i try .I've done as much research as could tried many different approaches to solve my issue is my tailgate camera the problem? or am I screwing up in the settings? please any insight would be super appreciated. i absolutely don't want to give up on this radio its super nice it hurts me to plug the old one back in lol
