I just completed the full integration of my MOTO E815 in to my 2002 X5. I bought the BT ULF module from AdvancedAutovations.com, and the eject box and snap-in adapter ( snap-in for V710 fits the E815 ) from Crevier. Everything works as advertised. The phonebook transfers, the phone charges, and the X5's built in cell antenna is being utilized as well.

Thanks to Rob for sending me the needed mini coax to fakra adapter so that I could use the cars antenna.
