I have a 2010 F-150 with OEM Nav system but I neglected to order a rear view camera. I have since purchased (eBay) a camera and installed it. Wiring harness was already there.
Everything looks ok but I get nothing on the Nav system display.

Does this have to be programmed on the Nav system or am I missing something else?

Help appreciated. I am a novice at this.

I think the reverse camera feed goes to the rear view mirror not the NAV. Not sure though you might want to look into it.
