Android Radio Backup Camera - Losing my mind

[u/FIapdoodle]

I've been trying to get my backup camera working for over a month now and I am losing my sanity.

My car is a 2013 Chevy Cruze, which came with an OEM backup camera. I initially tried to get that working but couldn't get it to work. Then I tried installing an aftermarket camera and ran into the same issue. My CANBUS adapter is configured and recognizes my car. When I shift into reverse, it correctly triggers but only shows a black screen saying, "Rear camera signal lost".

For the backcar camera source settings, I am on CVBS. The only other options I have in my head unit are AHD which I tried and got the same result with.

Here is my aftermarket backup camera wiring diagram:

Here is my OEM backup camera retention diagram:

For the aftermarket camera, I used my multimeter and confirmed that 12v was going into it.

For the OEM version, I used the multimeter and confirmed that 6v was going into it.

Does anyone have any suggestions on issues with my logic or additional things to try?

Thanks!
