For older Fords without a backup camera this module certainly does the trick. I had looked into many stereos and screens to use as a backup monitor to use with an aftermarket backup camera on the 2013 Ford Focus, but I was one of the few who actually liked the Sync interface and felt the OEM screen to be adequate to show a camera feed. Along with the Ford wiring harness and a camera (I found one elsewhere that integrated into the trunk release handle) this intuitively shows your backup camera when in reverse on the stereo screen and leaves everything else really stock. It also has 3 other inputs if you have other cameras or devices you'd like to display on your OEM screen, but I sold the car before I got around to playing with those.
