You forgot to mention that it uses the external antenna as RBAROR as mentioned.

I have the smartphone integration in my 09 X5 and I use the USB instead. I have been unable to get the music integration to work from the dock. I have noticed the better reception when my phone is mounted in it tho.
But for $286 I would order it just to have it. Maybe get your dealer to fix the music problem.
