The Up! has a radio system with an input that can see a camera - allegedly! I have been looking at what the Octavia enthusiasts do to fit OPC because it isn't just set a bit in the radio to get a camera up on screen, no, Sir!
Firstly it is necessary to fit parking sensors, then the gateway needs to be told it has a new travelling companion in the form of a 1S0 919 475 PDC control box (but whether that is an A or B suffix, I don't yet know,) drill the bumper, find a back loom and a central one, physically wire into the CAN BUS and then get the whole lot to work.
Once the OPS system is operational, I intend to fit a camera. First though, I need to know the part number of the sixteen way connector housing that plugs into the control module...
This might take a while but having already retrofitted cruise, I am happy to give it a go.
