ok i thought it was a onstar button on the steering wheel but i pushed it anyway and the radio screen said phone,,,so....how do i use this feature??

If you have your phone/Onstar service, then when you press the phone button, your radio volume cuts off and the phone turns on. If you do not have the service, it will take you too an Onstar advisor. I have mine activated with my Verizon service and I use it quite often. A little costly but not too bad....

oh, last thing i need is another phone bill..lol thanks for the info...i guess it wil stay doing nothing in my car LOL

The Onstar service is expensive.. That is why I added mine to the Verizon minutes.. to hve the phone in the car cost me an extra $30 a month.. and that is on top of the rate plan for regular minutes.. but I drive all the time and have to be on the phone too so this is much safer for me...
