New to the forum so here goes......i have a 2015 f250 and rear camera quit working. I researched trying to find replacement but to no avail. I call and dealership quoted 400$ for camera 40$ for emblem if needed and an hour for programming (about an hour at 90$). Before taking it in , does anyone have any suggestions as to possible causes for failure of camera? I have tried just about everything like fuses, connections etc. Also does it really take an hour to program??
