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
