Well, I have a much easier time reversing than I did when the camera worked, but the transmission didn't. Still, it's a feature that the car should have, that I just paid for, and while I can certainly look around, having it not work puts me in a bad mood every time I get into the car, plus it's still safer having the camera working than not.
In true intermittent problem fashion though, when I pulled everything apart to check stuff, it worked. Then when I put everything back together, it didn't. I guess I'll just leave the trim panels off.
Of course this raises the possibility that the problem is somehow in the trim panels. Maybe a clip pinches something somewhere in a way that it shouldn't, or presses on a wire harness. I guess I'll have to look through everything. What a royal pain in the patootie.
So more troubleshooting. Next is to take the dashboard apart, and check all the connections to the APIM.
