So I've got an '07 3.5SE and I had an old Motorola Razr V3. It worked just fine. Call comes in, I hit the button on the steering wheel and started talking.

Now I've upgraded to a new Razr V3xx, paired it with the car (by replacing the existing one), and now I have a full 5 second delay after answering before the calling party can hear me.

Any ideas?
