Why? Just don't use it and let the subscription run out.

There's a Volt specific link if you're paranoid enough. https://www.youtube.com/watch?v=i0dvLuWna9Q

Of course that's Gen 1.

Maybe he wants to "borrow" a Volt and disable the OnStar tracking so the "lender" won't know where he is. lol

I tried that when I was trying to get the date to stay right in my gen 1. You lose the microphone and cannot talk to anyone who calls, although you can hear them. It didn't fix the date either. Still always 1 day ahead. I guess Hal is on a permanent future trip! I think to disable Onstar without losing the microphone you have to unplug the Onstar module, which I THINK is in back somewhere. Too much trouble. And then they gave me 3 free years of basic, which is very basic, only key fob functions.
