Ummm... then whats the point? Its a backup camera. Meant to go on when you backup. It makes it easier to backup.
Because most of the time I am just backing up and have alot of room. I would rather control it when I need it. May change my mind later.
I am going to install mine to the speed wire but not the reverse. I did get a back up camera but do not want the camera coming on every time I put it into reverse. Most of the time I wont need it.
