Just a heads up to anyone wondering about the hitch install. According to the BMW installation instructions this is a 2 1/2 hour job. It is NOT. I have my X5 at the dealer having the hitch installed and have watched and talked to the tech completeing the install. He has been working on it for 4 hours and it is still not complete. Should be completed Monday, he has to finish up the wiring. One thing that is important is the computer has to be programmed before the install begins so I don't think this is not a "driveway job". Anyways, this is the Dealership's top technician and he said that he has installed numerous hitches on BMW's and this is not a 2 /12 hour job. The hitch looks massive bolted on, can't wait till it's complete. Anyone else have the hitch installed? How long did it take?
