So BlueTooth is working fine now in my 5/04 production X5. The dealer upgraded me to the combo BT/Assist module and it works great with the V710 running 1.02SD. Now I think I want the new snap-in adapter for the 710 that replaces the oddment tray. I saw it in someone else's car and it wouldn't charge the phone. Apparently the dealer tells me there are two snap-ins. One that has a pairing button and doesn't charge and one that has no button (not needed w/'05 module) and does charge the phone.
I asked the dealer parts department locally here what I would need to put in the one that charges. The parts guy researched it and called me back to say I'd need the following (wondering if this right):

- Dock $~140 Part # 84210393570

- Eject module (?) $~72 Part # 842169334151

- Base plate for bumper antenna $~82.50 Part # 84216946063

- Bumper Antenna $~63.75 Part # 32684111470326

Seems like a lot of stuff, but have heard I'd need an antenna since Assist uses the one in the car already. Any guidance appreciated.
