Cameras Support
PVS camera knowledge base: reverse and auxiliary cameras, wiring, formats (AHD/CVBS), and multi-camera setups - with troubleshooting first so you can fix issues fast. For headunit-specific MK4 paths, see Headunits → Cameras.
Troubleshooting
-
Black screen, rolling lines, or wrong picture on reversing
Format mismatch, cable faults, and adapter checks before swapping the camera.
-
No reverse image or camera never switches
Trigger wiring, headunit input priority, and relay paths.
-
Flicker, interference, or image cuts in and out
Ground loops, alternator noise, and long-run coax shielding.
-
Camera dead - no LED / no power at the camera
Tap points, fuses, and verifying 12 V under load at the tailgate.
