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.

Crutchfield Customer Review (What's this?)

Other than the cable being way too long, the cable works fine. Recommend Garmin offer 5 meter, 10 meter in addition to the existing the existing 15 meter lengths



Good accessory for a mediocre camera

Big Vic from SF Bay Area on 1/19/2014

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

Crutchfield asked  
Why did you buy this?

I will be using this on the 37 foot 5th wheel camper.[ Douglas  Nov 28, 2016 ]
I chose the Garmin 50' Extension Cable because I will mount my Garmin BC 30 Back-up camera on the rear of my RV. I want to mount the transmitter at the front of the RV so my receiver will get a stronger signal.[ Jeffrey  Sep 21, 2016 ]
OEM manufacturer of BC30 camera cable is too short for my application. This cable is too long, but is only option.[ Howard  Jul 31, 2016 ]
Being installed on a 7x16 Enclosed Trailer. Need the extra length to keep the transmitter on the tow vehicle. I have a BC-20 I use for my Boat Trailer that is roughly 36' and it works very well towing a 27'+ Pontoon boat. Especially backing down a curved sloped driveway with plenty of obstacles![ Dave  Jun 24, 2016 ]
It will be going on a fifth wheel trailer[ David  Jun 22, 2016 ]
Works great on my 35' 5th wheel![ KEN  Jun 05, 2016 ]

To go with my gps[ steve  Feb 24, 2016 ]
