We have just purchased an RV trailer. It weighs 4900 pds. My Bimmer is rated for 7500 lbs. I need to add a back up camera. However my dealership has said that they do not recommend trying to wire in a camera or wiring anything into the Bimmer electrical system. Does anyone have any experience with this?

Thanx in advance

Welcome to the Forum

My wife is a Horse rider so we tow a trailer quite often. She likes to know how the horse/horses are travelling so I fitted a wireless camera inside the trailer which communicates with a tablet. Later I fitted a second backup wireless camera to the trailer that can be used on the same tablet.

Both cameras are powered from the trailer lights which are on with my DLR's when I am towing. As for connection to the car when the trailer is plugged in my Park assist and rear view camera are disabled so the tablet was a simple solution.

Hope this helps

Our motor home has a wireless camera which shows on the mirror when you select reverse. 
 

it is powered from the 12v or the interior light and the camera and signal become active when I select reverse as it’s wired to the reverse light. 
Its wireless so no problems if you unhitched and forgot.
