Car backup camera Garmin BC 40

The Garmin BC 40 is a wireless car backup camera designed to assist drivers with rear visibility. The camera provides a 150° field of view and streams video at 15 frames per second. Water-resistant with an IPX7 rating, the BC 40 withstands exposure to heavy rain and splashes. It operates without hardwiring, powered by two AA batteries for a battery life of up to three months under typical use. Compact dimensions (158.5 mm width, 24.9 mm depth, 21.8 mm height) allow flexible mounting on a camper or other vehicle surfaces using the supplied camper mount and screws. The camera communicates wirelessly with compatible Garmin devices within an 8-meter range and supports simple voice commands to initiate the camera view.

Advantages

The BC 40 eliminates the need for a wired installation and relies on AA batteries, simplifying setup and reducing installation time. Its IPX7 water resistance provides reliable operation in wet conditions. The wide 150° field of view captures a broad area behind the vehicle, while the compact form factor enables installation in restricted spaces. Wireless connectivity with an 8-meter range offers flexible placement relative to the display unit, and voice control allows hands-free activation of the camera view.

Suitable for

• Trailer, camper, or caravan rear monitoring
• Passenger cars where wiring is impractical or undesired
• Temporary or seasonal installation for towing or loading tasks
• Positions with limited mounting space due to the camera's compact dimensions

How to use

Mount the BC 40 using the included camper mount and screws in a location that provides a clear rear view.

Pair the camera with a compatible Garmin display by following the device pairing procedure in the display's settings.

Regularly check battery level and replace batteries as needed to maintain continuous operation.

Usage recommendations

For reliable performance, mount the camera where it is protected from direct impacts and where the lens remains free of dirt and obstruction. Test the camera view after installation to confirm angle and coverage, and keep a set of spare AA batteries on hand for extended trips.
