The back-up camera on our '08 Camelot is movable, but the design of the permanent housing doesn't allow it to tilt high enough (plenty of tilt to see the hitch, tho).
I tried to adjust the mount, but no luck. So I called Voyager (ASA Electronics) to ask if I could buy a u-shaped bracket and mount the camera in it.
The very nice lady said that camera had been out of production for years, but she'd check the warehouse to see if they might have a bracket laying around.
I just received a new bracket from her - no charge.
Thanks Voyager!
