I have an xv6600woc which I use in an '05 BMW. The xv6600 tells me it's successfully paired. I can send and receive calls through the car sometimes. I cannot load the phone book into the car or dial from the phone / navigation unit in the car. There are a couple of other phones that do work so I have to believe that the xv6600 software needs to be developed further.

I have the latest Audiovox update and have tried the BT3900 patch.

Any ideas if Audiovox or anyone else is working on an upgrade which fixes the xv6600 interface to the car? When will it be available?
