I recently tried to connect my 2025 GLE 450e to my RV trailer brakes using the Teconsha Prodigy RF wireless brake controller. Had no luck getting the controller paired with the remote. Can this system be used with my GLE 450e?

 

@mikapen uses that controller and might be able to assist.

 

Do you have 12 volt power at the controller?

 

Hi, I don't have a Teconsha but I use a Curt Echo Wireless brake controller. They won't start working unless the trailer/rv is hooked up. Once hooked up it starts showing up in the app for pairing and further configuration. I believe your wireless brake controller will work in similar fashion once you have hooked up everything and have the car turned on. Give it a try.

 

I found that my Curt Wireless controller would pair with my smartphone, but completing the setup does require connection with the trailer system. Everyone should have a test plug device like https://www.etrailer.com/Electrical-...URT/C73NR.html that confirms all the vehicle functions are working properly -- $20 well-spent.

 

One other possibility -- the installation instructions that came with my Curt controller advise that some vehicles that come with a factory installed tow option may need to have the 12 volt power to the 7-way connector activated somewhere in the car settings menu. Check your OM to see if this could be your problem.
