Just bought a new edge about 3 weeks ago. I got almost everything on it, except the backup camera and the towing package. I was wondering if i could find a factory camera, would i be able to mount it, an use factory wiring to keep from running new wiring? I guess what im asking is will my edge have the wiring in place for the factory backup camera, even though it didn't come with it? I got the navigation system, and was thinking i could add the camera in. Also, how hard would the backup sensors be to add in as well?
