I have a 2014 Volt and my 3 free years of Onstar just ended. I did not renew it. Today, I tried to make a call through my bluetooth connection with Volt and instead of putting the call through my speakers, I got a loop recording telling me to press the blue button to renew Onstar. A second try led to a recording loop requesting to enter my account number. Is Onstar required to use my iPhone/bluetooth connection?
