I ordered a 760LMT with the idea to install the wireless b/u camera with it. The GPS was great, but after trying 2 Garmin cameras and not being able to get them to work with the GPS, I sent both the cameras and the GPS back. I later bought another 760LMT to use in a new motorhome that already had a b/u camera. This unit was a factory refurbished unit, shipped with the wrong USB cable and, using a Garmin cable that I already had for another Garmin product, wasn't recognized by the software program, thus unable to update maps, software, etc. Sent it back.
I like the features of the unit, particularly bluetooth capabilities and the hands free speech recognition. However, given the issues that I've had with the units, I'm leery to order yet another unit from them. Your mileage may vary.
