In this video, we install a Bluetooth adapter for the stock radio on our 2007 BMW Z4 Coupe. The adapter used in this video was purchased on eBay and we ended up having a few complication with it. I would recommend purchasing an updated/better quality adapter from Amazon (this one worked great in the convertible):
