It is possible as the ford screens and mirror are signal sensing units. Meaning that even if it sees a reverse signal to the mirror or radio it wont go into the mode unless it sees a video signal.
Easies way to tell is to check the connector at the back of the mirror for the video wires.
Joined to do some research on the vehicle itself as well as programmers and aftermarket goodies from people who own them. Looking to purchase mine here in a few months.
Thanks for your time.
