'Works just great
Once easily fitted to car, the cables that are already in place, just need connecting.
After which, once in reverse gear, the screen immediately starts to show the area behind car.'
I fitted it to my w204 c class.
It was not exactly the same as mine has a bulb in as the clear part as the whole thing replaces one of the rear number plate lights.
I connected it via a relay to the the reverse light and power from rear sam using addafuse. ( Relay needed to give it a clean feed)
I ran the video cable to the comand under the offside trim. Fashioned a fakra as the rear of the comand was a double fakra.( I bought a fakra from ebay)
Then set the comand to operate camera when reverse selected.
If its a comand your connecting it to, make sure you get a NTSC version as not matter what your comand says, you cant change it to PAL ( It looks like you can but it wont save the setting) ( I suspect Richard or Alfie could with their equipment)
