Dave I had purchased a launch xpad off eBay a few years ago. I didn't pay attention to detail, and found only after receiving the xpad kit that it was missing the very small Bluetooth diagnostic connector. I found that our Mac dealer supported it, and a few week's later and a few hundred dollars, I had a replacement. It was fairly easy to link the new diagnostic connector to the xpad. Just my experience. Also I noticed it had a very noticeable audible alert when ending communication with the vehicle.
