I have the bluetooth on my '09 Cobalt and it works great. Same with the USB connectivity for ipods. When you read the number that you want to dial it displays it on the radio. It works exactly like dialing with OnStar except when your phone is paired with the system it uses that to dial rather then onstar. The only thing i've noticed is that when I dial, you don't hear the phone ringing, you hear nothing til somebody says "hello".
