I renewed mine. I've already used it to make calls in the middle of nowhere, to find out what's wrong with my truck so I could fix it and to get the closest tow truck to get me (Hummer paid for the tow truck, but OnStar made it convenient). It has more than paid for itself. The peace of mind alone is worth it IMO.
If you get rid of it, you can no longer say, fu
ck it, I've got OnStar.. right before you do something stupid.
