I have one in my Mustang and love it. I'm trying something different with the ST. Since I only want the backup cam & not the other features I bought a different kit from oemautopartsco:
OBD Genie Ford Rear View Camera Programmer Kit F-RVC-F2T
I get it Friday and will give it a quick install - I've already ran the cam from the hatch to the area by the glove compartment.
Edit: I have no experience w/ the air version so no clue how streaming the phone to the screen works.
