So I came across a rear view camera with a trick rear view mirror on eBay. A 4.3 TFT screen appears on the rear view camera when you select reverse gear. It looks like a normal mirror when not in reverse. For under R600, I thought it was worth the risk getting it on eBay.
It took me 30 mins to install as there is no wire from the camera to the mirror. It works wirelessly. Camera draws power from the reverse light. Mirror draws power from the maps light.
For the money spent, it was well work the investment. It's a bit fuzzy when I first tried it but found it worked 100's with the engine switched on. I tested it on ignition only when fitting and found it losing signal or fuzzy on the display. When actually using it, it works fine. It also has the distances lines to guide you so you have some idea how far an object actually is from the rear.
Just thought I'd share and hopefully help someone else in this area.
