Pioneer AVH1300-NEX backup camera not displaying!
Installing a pioneer AVH1300-nex.
Everything works except the backup camera display is black. When I put it in reverse the H/U switches to backup camera mode and it says "image may be reversed" and shows the parking assist lines. I move the gear selector either way and the H/U goes back to regular mode.
I know the camera works when i put it in reverse because I have a separate video monitor it displays on. It turns on when I select reverse and off when I select another gear.
-head unit works
-reverse triggers a backup screen
-screen is black with warning message
-backup lines show
-hooked into brown port "r/c in"
