I have a Garmin GPS small model that has the option of receiving an image from their optional BC 30 wireless camera. The camera is easily mounted unobtrusively at the center of the grill portion right below the solid part of the bumper. It gets power from one of the backup lights which is easy to connect to. All wiring can be hidden in the shelf of the bumper under the car. Cars panels don't have to be removed either. When you shift into reverse it automatically comes on. The backup lights also provide more than enough light for lighting the rear view at night time too. I like that this provides an excellent GPS navigator, backup camera, and even wireless connection via USB to my Android phone. I just leave the phone in my pocket and when in the car it auto connects via USB. When a call comes in it runs through the Garmin including voice control. The mike and speaker of the Garmin are used rather than the phone. You have to make sure that your model of Garmin supports the wireless camera....these come in various sizes and models.
The one I have is the smallest size....DriveSmart 50 LMT 5". That LMT designation indicates it is the version that works with the camera. There are NO wires that run into the cabin....it transmits from the camera to the GPS via a small receiver block that is part of the power cable for the Garmin that comes with the camera. Very tidy setup and has worked flawlessly for me for about 3 years.
