Bottom line:

If you have no video input device, VSM is the way to go. Much cheaper than a TV module and offers the a/v integration you need.

If you already have the TV module with camera input, just get the camera and a relay. You may need the AV harness for the TV module if you don't already have it. This has the AV RCA inputs including one for backup cam.
