2 or 3 times in the past I was not able to connect to OnStar when trying to call for directions. The phone would show on the radio display but all I would hear was a beep every 15 to 20 seconds. I figured the satellites were in poor positions.

The beep is indicating that you are waiting for an Onstar Rep to pickup, not that you are not in range.

I knew the phone feature was through Verizon, but thought calls to OnStar were satellite. There are still a lot of places in this country where cell phones do not work. Hope we are not in one of those locations if we have an emergency.

I was told by an Onstar rep that if a Verizon Cell Tower is in range then it will use the Cell Tower. If there is no Cell Tower in range then it will use the Satellites.
