Manufacturer DescriptionKeep a Watchful Eye on What’s Behind YouShows what’s behind your vehicle when in reverseView footage right on your GPS navigator’s display* (sold separately)Wire to constant power and toggle easily between camera and navigation modesWirelessly transmits video up to 45 feetRugged enough to withstand harsh weather A quality backup camera like the Garmin BC 30 can significantly enhance rearward visibility for drivers and, thus, help minimize the risk of “blind zone” accidents whenever your vehicle is moving in reverse.Take the Worry out of Backing Up When paired with a compatible GPS navigator, the BC 30 wireless backup camera helps you easily spot vehicles, pedestrians, pets and other hard-to-see obstructions behind your vehicle. If the camera is wired to your reverse lights for power, your navigator can automatically display camera footage every time the vehicle is shifted into reverse – and go back into navigation mode when shifted into a forward gear.See Clearly What Needs to be Seen As another option, you can wire the system to constant power, which allows you to toggle between the navigation display and backup display modes at the press of a button. The transmitter will send camera footage to your navigator’s receiver mounted up to 45 feet (13.7 meters) away (range varies based on installation; some vehicles may require an extension cable, sold separately).Professional Installation Recommended For installation, Garmin recommends taking the BC 30 to your dealer. But if you’re a diehard do-it-yourselfer, that’s an OK alternative as well. You’ll need to mount the camera on the rear of your vehicle and connect it to a power source, such as the rear lights. The BC 30 is rugged enough to withstand even the harshest of weather. And up to 4 cameras can be used together in 1 system, for multiple viewing angles. *Software update may be necessary when pairing your compatible navigation device with BC 30. Range varies based on installation. Professional installation recommended. Vehicles that do not provide constant minimum voltage may require the installation of a relay (sold separately).
