In the new X250 an option is rear camera I have heard that the wiring for this is already in the loom and it terminates near the rear view mirror with a connector plug.
Is the above true and if so has any one a wiring diagram and exact area to find the plugs.

I have had a look behind the cab courtesy lights and there is a spare cable with connector.

Does anyone know the price for the OE reversing monitor and camera and also how much would it be to have fitted?
