It'll be a bit of a job. You'll need a new nav unit with the camera input, the reverse camera module and the camera + wiring loom for the tailgate. I put a video on here a while back which shows the camera, wiring loom and reverse camera module.I have a brand new 2015 Mondeo Estate all the bells and whistles but forgot to tick the box for the reversing camera.
Can this be retrofitted ??
