This is what I bought:

Item: OEM BMW Hands-Free System with Bluetooth Technology
Price: $485.00
Tax: $0.00
Qty: 1
Total: $485.00

Item: CABLE PIN ADAPTOR
Price: $14.00
Tax: $0.00
Qty: 1
Total: $14.00

Item: INSTALLATION KIT
Price: $131.20
Tax: $0.00
Qty: 1
Total: $131.20

I got all of it from getbmwparts. For some reason, the emailed invoice did not contain part #'s. I *think* the install kit was the center console pairing button assembly. And I *think* the cable pin adapter was for the connection between the pairing cradle and the cable in the center console.
