V710 with 1.40OR Firmware and BMW BT

[Kewl X5]

Okay, now that Verizon has released 1.40OR Firmware and I have it downloaded to my V710 which BT module should I get to retrofit in my 2001 X5?

I know Parag had BT modules that you could retrofit to the 2001 X5.

Currently, I do know that the 2005 BT/Assist combo module does allow the V710 to not only pair up, but also have the address book transfer to the car.

Now, rumor has it that even the latest BT standalone module -522 will pair up with the V710, BUT it won't transfer the phone book. However, I haven't confirm this. Has anyone else research this issue.

Yes, I am aware of SuperDave's firmware, but since I have the 1.40OR firmware and it does fix alot of bugs on my V710, I would like to keep that firmware.

Thanks in advance.
