Confused...
 

I'm getting my '05 X5 next week which has the bluetooth already. My confusion comes after that part. Do I need the snap-in or the voice control module? Thanks in advance..

Do you need them to use BT? No

Can you add them if you want them? Yes (either one or both)

Note that if you go with the snap-in adaptor then you'll likely need to also add a 2nd antenna to the vehicle, as the one that comes with the vehicle is being used by Assist.

Thanks! I think I'll add them both. I'll get the part numbers from the other threads. Thanks again.....
