Not sure what's causing this, but my backup camera will sometimes work, other times it won't. It's completely random, nothing causes it to work, nothing causes it to not work.

Only thing I've changed related to that system is my head unit, the aftermarket apple car play screen, similar to the Lexion unit, but I installed that years ago and its worked since. One thing I noticed is the screen seems to lose CAN data whenever the camera doesn't work, like it cant detect the doors are open or if there's an AC condition change.

Any ideas?
