sync problems

Hey all,

My old phone worked great with the sync on my sr5 but I just got a Droid x and cant get get it to sync phone calls. When I paired it and tried to make phone calls it says no audio. It will stream pandora through the car but when I try calling the phone it wont go through the car. I've tried a number of things including: reseting the Pin; repairing the phone; and pairing my friends iphone and every time we can only stream pandora through the bluetooth and not phone calls. Does anyone know what Im doing wrong? Thanks
