Just check that the HU has a RCA video input and also a remote wire to trigger the camera on, although I guess if it is manual it wouldn't be too much of a pain....
You then wire the camera to your reverse light wire so it gets power when the light is on and run the rca video to the HU and remote wire if needed, so yeah all pretty much plug and play.
Have a search for BM's guide on here I used the exact same camera from eBay took a little while to arrive from China but for less than £20 you can't complain
Thanks mate, the camera feed at the back is one rca connector (female). Then there is a wire which I have connected up the the reversing gear which will trigger the camera. I just want to find a suitable camera that will work. There seem to be a lot on ebay. Do you know where I could find the thread?
