Question:
On my 2025 Forrest River Flagstaff trailer, which has a Furrion S rear camera fos43tasf that is not working with my 2023 Mercedes GLE. It initially shows the rear picture momentarily then says no-signal then back to picture again. It keeps cycling that way. The camera works fine in my other vehicle, so I dont think its a camera problem but rather inadequate power problem in my Mercedes. Do I need an adapter or what do you suggest? B/R, Randy

Expert Reply:
Hey Randy, yes the issue is the power supplied to the running light circuit of your 7-way trailer wiring on your Mercedes which is causing the camera to not operate properly. What you need is the Furrion power adapter # FR87PR and you'd be set. This gives a stable power supply to allow the camera to work like it should.

Hey Randy, how did things go after adding the Furrion power adapter to your Mercedes? Did it keep the camera signal steady this time? Your update could make it easier for others with the same setup.
