V710 original software with -522 bluetooth module.

I had a V710 with the original software. Two weeks ago I installed the part #84 21 6 934 552 bluetooth module into my 2003 X5. I paired the phone and car together and everything was fine (except the phonebook would not transfer). This past Friday Verizon gave me a new V710 with the newest software 8700_01.40.0R. I paired it with the car and now I have problems. The phone constantly disconnects from the car. Will I need the Bluetooth module recoded by the dealer, or do I have to find the newest bluetooth module?

Thanks in advance

It's my opinion based on what I've been reading that the 1.4 firmware from Verizon corrects the compatiblilty issues with the combo BT/Assist module (made my Motorola and installed on the 2005's) but it makes it incompatible with the Pre-2004 BT module made by Visteon.

The Verizon store hadn’t shipped my original phone to the warehouse. They gave me my original phone back. So, I live without the phonebook transfer, but at least bluetooth is working.

I agree with you I have a 04 X5 and the V710 with 1.40 software and installed a 84.21 6-945387 does not work...I just had the new 05 assist/bluetooth installed and everything works fine.
I think the key is both the TCU and V710 are built by Motorola.
