Input behind screen on 2012 mk3 focus

[Over88MPH]

Any ideo what this yellow input behind the screen is for? Its on the back of the information screen / Sony dab radio.  Is it, or could it be used as a video input?

This is the rear view camera input.

This input is only active if the original rear view camera and rear view camera are connected and activated and the car is in reverse gear. If the originalcamera and module are present the rear view camera communicates with the rear view camera module. Next the rear view camera module uses the CANbus network to comunicate with the display to unlock the camera input

It is also possible to unlock the camera input of the 4.2 Inch Sony display by loading custom firmware. However this is not a free solution The custom firmware is developed by some clever Russian guys who sell it commercially.
