Hi Russell, I have exactly the same question. Picking up a new ranger in January existing van has rear view camera and I want to connect vans camera to Rangers built in system.
did you have any joy as Ford don't seem to be able to help.
I would like to avoid a second unit if at all possible. I cant see why not as my present system on my Disco3 has two channels one for towbar and one at end of caravan.
