I figured out how to get bluetooth audio working on my 3GS in our new 2012 x5 50i but the "controls" for the audio are weak. All I can do is skip forward or backward. Is this everyones understanding? I call BMW NA directly and they told me Bluetooth Audio was not supported on the 3GS. I did a quick search here to no avail.

Should I just use the USB cable instead?
