Hi there, im new to the forum..
i have done the exact same installation yesterday but WITH a module.
i have the exact same problems as yourself though.. default screen in Optical Parking System, then having to press an icon to see the rear image.
and also when the rear image is on, there is no OPS display of the car, just a blank area..
i don't think the module is what you are missing for it to work, must be something to do with VAG COM? maybe..
