I have the camera kit and it seems to work just fine.
The issue I have right now is the best way to power it.
It can be powered "always on" and placed in the camper's rear window. You then toggle the camera display on and off with a touch to the screen.
It can also be toggled on and off via power from the "reverse lights" line on the Bargman, but the camera would only work while backing the camper. Using this connection, you don't need to touch the display at all; you just put the TV in reverse and the Garmin switches to camera feed automatically.
