I have the Garmin 760 LMT and the BC-20 back up camera. It all works very well.
Camera image is far from HD quality,but it is adequate as a back up camera.
There is no night vision lighting,camera does not work very well in the dark.
Nevertheless the camera is a nice option. Being able to use the Garmin display is a tremendous plus. You can switch between camera image and map view with the touch of a icon on the display screen. The biggest advantage of the Garmin camera is that you don't need a separate monitor for the Back up camera. The Garmin GPS display can serve both purposes.
My camera is mounted on the rear of my 40' 5'er. I had to order the extension cable ($35.99 ? additional) to get the image to display properly. Without the cable the camera image was erratic and went in and out.
In the end the install works well. For less then $200.00 I added a decent back up camera. I have had the set up for 2 season now without any issues
