Voice dialing bt- jvc kd-a805

[euromade]

Is it a system limitation on my Droid or is it on the head unit? In either case, I am not able just to push the PHONE button on the head unit and voice dial. The head unit displays "connection error".

If I initiate a call from the phone I can talk but in some cases the phone hangs and then I need to reboot the head unit, to "unfreeze" the phone.

Any ideas if there is a software patch/update available...
Thanks!
