I bought this for my MG ZT-T (xTrons) and R75 (WinCE):
Bought this camera on AliExpress @ OTERLEEK Official Store
Installation could not be simpler! Place the camera/license plate and place the transmitter somewhere in the 5th door. Wire the camera to earth and the reverse light. (OK, that's a bit more difficult but you can easily guide the wire through the rubber tube of the fifth door).
Place the receiver somewhere behind the passenger side foot well and connect the cables to the NavAll. The NavAll has a reverse wire you will need to connect (search this forum) and then you are ready to go. The camera takes a few seconds to activate and the image is crystal clear :-)
Good luck
