Im guessing based on the manual need to find a wire to connect it to avic920 violet/white wire to behind the dash. DOES anyone know of a good connect wire for reverse behind the head unit?
I am not sure if its the same with the avic920 but with my AVH-P4200DVD, I had to connect the RCA cable from the back up camera to the brown female RCA input behind the HU.
If you're seeing it using the AV2 source in your HU, you probably hooked up the RCA from the back up camera to the wrong female RCA.
I know because I just had this problem where I could only see the video from the back up camera when I am in av mode.
You should see if there is a separate video input for back up cameras in you avic920's manual.
Also make sure that the HU knows which current change it should look for. If you tapped into the positive backup light wire, then you should set the camera polarity to "battery" in the settings. If this was set correctly, your HU should switch to the back up camera input when you put it on reverse gear. I dont own an avic920 but its probably similar since they are both from Pioneer.
