Bluetooth

I just purchased a Motorola v710 bluetooth phone to hook up in my '05 X5 4.4i. I read all directions and followed step by step.

Looks like the phone and the X5 paired because in the Motorola phone, under bluetooth settings, I see the BMW letters and the last 5 numbers of the vin.

I tried calling the number 10 times and the phone rang but the X5 didn't do anything. I tried to answer the phone with the speak button on the steering wheel but nothing happened. What am I doing wrong?

Also, I notice that the phone says "connected" to the BMW and sometimes says "disconnected" for a moment and then reconnects. What does this mean?

Appreciate all who answer. Thanks.
