No, not yet. I just got the pigtail for my Tacoma and used my old Prodigy controller for the most recent trip. I'm not sure we'll actually use the X5 to tow, which seems crazy after spending the money to get the hitch installed. But I may still pick up this controller in the future....

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
