Prerequisite is a TV-module. These are available in analog form for next to nothing these days, tho, as everyone is switching to digital:

You either buy a kit with the cam/relay/harness for around GBP150 or you buy an NTSC cam on ebay for GBP25 and a relay from an auto parts store for GBP5 and make your harness. This cam works very well in a RR, BTW, although you do have to file a little metal inside the number-plate light slot :shock: .



The cam is wired into the TV module:



Pins 13 and 14 on the white plug are vid in. Pin 17 on the blue plug needs ground to switch, so what you do is this:



The coil in the relay is energized by the reverse light (pins 85 and 86 on the relay) and closes the contacts (pins 30 and 87) switching ground to the vid module. You can add the manual switch to gnd like this guy has too. That way you can see if someone is following much too closely. Or watch as you're being rear-ended at a traffic light. Or add another relay and switch between vid sources (such as a DVD player). Or...

Female connectors are avail for little money at BMW Part-No 61 13 0 005 197.

The camera pictured above is quite unobtrusive and replaces the light with an LED as well as adding the camera:


I don't have any pics of my own RR handy and I couldn't find any on the www with a quick search, but here's a Disco3 that shows how well it's hidden:

For the perfect install you have to replace the other plate light with an LED as well and program out the bulb test.
