Garmin makes a GPS that I can connect one of their rear cameras to for backup viewing. has anyone used a Garmin? cost for both is about 320.00 not bad for a wireless system and GPS
Our rig came with the Garmin and really like the camera. Like that when going down the road you can use the camera to see directly behind us. Big help when backing in. Ours has grid lines you can adjust to various widths to help lining up when backing.
