Review on Enhance Safety with Garmin 010-12242-20 Add-On Camera & Transmitter for BC (TM) 30 Backup Camera by Christopher Clearfield

Mounted on the back of my 32ft RV. Used their 50ft extension cord and mounted the transmitter to the front of the RV. It takes a few seconds for the GPS to switch to the rear camera, but after my three and a half week vacation we've just returned from about 3,000 miles this thing has saved my ass a couple of times. This allowed me to shoot my rig in places I would not have dared without this camera as it was too dangerous to mount and for anyone who could get out to guide me back. The camera is a fish eye so it's mounted at a 45 degree angle and I can see the entire back of my RV and the sky as well as several vehicle widths either side of the back of my RV. I was also blown away by how you can adjust the guides to suit your setup, lifting them up and down and spreading or contracting them to be perfect for your use. You can remove the guides with a simple tick in my GPS if you want, but with the ability to customize them so much I don't see why anyone would want to turn them off. I use this with a Garmin RV 770 LMT-S. For an RV or truck this is the best GPS I have ever owned and paired with this camera is essential.
