Onstar sent out an email shortly after they made the announcement about the tracking. They have revised their position on it and will completely disable the Onstar feature from your car when you cancel. The only way it can be returned to service is if you push the button. Even if your car falls off the face of the earth - unless you push the button you'll be on your own.

They don't track your movements. However, they do track how you drive and vehicle speed. The only thing they do with the information is for GM research, unless law enforcement requests the information then it can be turned over to them with proper procedures being followed like responding to a court order.

I don't have onstar but, it sure sounds like a great idea to me. Much more reliable than any cell phone I have ever heard of. Lots of places there are no cell service or reception. Better save than sorry. I'm not paranoid.

Like having insurance and security service for a business
You sure hope you never need it, if you do its there.

You can go with the less expensive option if you don't need the directions. I think the peace of mind is totally worth it. I'm on the road a lot and there's not always cell service.
