Hello everyone, I located the bluetooth antenna. It was located under the gear shift lever. I recently had my X5 in the shop for a few recalls. One of the recalls was the air bag recall. I had no phone issues and it worked prior to the service. After making several phone calls after the service, my wife said the reception was really bad, both the receiving end and car reception.

I went on a few BMW forums and it was reported that when they had brought their X5's in for a service recall, they had the same bluetooth issue. A call to the dealer was made, but said they didn't have a reason to mess with the bluetooth antenna. My next thought it was a phone issue but after testing 2 different paired phones, I went outside the box.

My son is a mechanic at a large Cadillac dealership and located the bluetooth antenna and sure enough, it was unplugged. He also said there is a snap ring on it so it won't come unplugged. Too bad stealership wouldn't take responsibility for it! It's fixed and works fine!
