We purchased a Furrion FOS07TASF 7" Vision S Wireless Vehicle Observation System: 7-inch Monitor and 1 Rear Sharkfin Bracket Camera from Amazon. Not cheap! We installed it in our Airstream ourselves and took every precaution to do it right. It worked with our 2016 GMC Canyon PERFECTLY. We took it on one trip and when we returned we traded the Canyon for a 2019 GMC Sierra 1500 Denali. Camera WILL NOT WORK! We are so frustrated. It will pair when paired with the pigtail in the truck but even when the camera is on the back of the Airstream and the monitor is AT THE BACK of the Airstream (inside and plugged to 12 volt) it will not pick up a signal. We are baffled. We have spent hours (lights are on, etc), have unpaired and repaired... no picture and no signal. Amazon says the "return window is up" (less than one month). I guess a Voyager will not work, either?!
UPDATE: My husband and I have never received such customer service! Furrion's "head of customer relations" called my husband and their engineers have a fix for this problem. It is a simple plug in that they have tested and it works. It plugs in the 7 way and boosts the voltage to the camera (ours is wired to our running lights). To top it off they are overnighting it and sending it free. We are overwhelmed with the service. It is not their issue (it is GMC's) and yet they have worked out a fix. Rarely, if ever, have we had THIS sort of exemplary service. Will update again when we receive and test the adapter. GMC, if you are listening (and you should be) why not RUN on over and patent this adapter now from Furrion?!?!? (I have no affiliation!)
