I retired my V551 Motorola phone and purchased a new Windows Mobile Smartphone (Audiovox SMT5600) so that I can better synch with my happenings at work. The problem is that it doesn't work worth a crap now with BMW's Bluetooth system. I can get through the device registration but that's it. No address book, can't make or receive calls (although I've been told that calls go sometimes but I don't hear a dial tone or response from the system.)

I have a 2005 X5 4.4i and had no problems with the V551. I also had a V600 for a while that also worked fine. I know that the Audiovox isn't on the "list" from BMW but what's up with their Bluetooth system? The phone works fine with Bluetooth headsets, including Motorola ones and Bluetooth is supposed to be a "standard."

Can anyone shed some light on this? Is BMW planning any upgrades so that it works with more phones?
