Pairing with a new Camaro

[Spartan304]

Does anyone else out there own a new 2010 Camaro? I just got mine today and pairing my HTC Touch Pro with the car went smoothly. However, if I go back out to the radio and attempt to make a call, it drops the connection. Also, if I receive a call, the car never picks up on it and also will drop the connection. My bluetooth options are all set to on and visible and my phone works fine with my current BT earpiece. I've deleted the car from the phone and the phone from the car several times and re-paired them with no success. Is it possible that an updated BT stack or homebrewn ROM will fix this issue? I'm currently running the stock rom from Alltel. TIA!
