I have a 2004 330Cic with Nav (Production date: 2003/07). My car is pre-wired for phone but does NOT have Assist or Bluetooth.
I want to add the OEM Bluetooth to my car and I have found this on EBay: 84 10 9 132 711
Is this a combo BT/Assist module? Will this work with my car? I don't care about the Assist.

Thank you
