Hi Guys -

Got the factory hitch installed on my 2011 X5 at JMK BMW in NJ. I did not want to run a cable to the front and permanently give up my cup holder with the factory brake controller option.

I went ahead and bought the Tekonsha Prodigy RF Wireless Brake Controller from Amazon. I installed it on my featherlight open trailer (weighs a little over 1,000 lbs). I tow an E30 BMW on it. I have towed once and the brake controller works great.

I was a bit concerned as I had the trailer serviced and upgraded to LED lights and wasn't sure if the LED lights will confuse the brake controller. I did have a glitch when I first tried to do the "handshake" between the wireless unit and the trailer mounted unit but I went ahead with the steps and it all worked fine.

Tekonsha recommends that the unit should be installed on the outside face of the trailer arm but I installed it underneath and out of sight and it works fine.

Here is a picture of my X5 hitch install, the dealer was kind enough follow my instructions and carefully cut the bumper as little as possible.



YMMV
