Our take on the Garmin Wireless Back-up Camera Extension Cable

Add some versatility to your Garmin wireless back-up camera

You've got a Garmin portable navigator and a Garmin BC 20 wireless back-up camera for added safety when shifting into reverse. The problem is your new RV or trailer is longer than the range of the camera's transmitter. Or your vehicle has some metallic surfaces or appliances causing interference that you need to get around. Garmin's got your back with this handy 50-foot extension cable, which lets you extend the camera's range without a complicated installation. Simply plug the cable into the back of the camera and connect the transmitter at the other end where it's within transmission range of your Garmin navigator. You'll be backing out of parking spaces safely in no time. Warranty: 1 year.

Good accessory for a mediocre camera

Crutchfield Customer Review (What's this?)

The cable is good enough for what it does, but the issue is the camera and transmitter it augments are only capable of providing a grainy low quality video quality to the GPS.

Pros: Extends the range of the BC-20 camera

Cons: Poor transmitter video quality with or without this cable Connections not waterproof
