Is OnStar protecting your vehicle??

I have OnStar and have never had to use it other than to get them to unlock the vehicle once. It also tells my dealer when I need an oil change which is useful, and not irritating since I like the dealer's service people. I bought the vehicle after seeing an ad for OnStar, incidentally, but that is not what closed the deal for me. It was a good bonus. I agree it is a nice benefit. As for the phone - It gets better reception than the cell phone and I thought that was because of it working off a satellite but thanks to this thread it looks like that is not the case. Either way I don't go off the beaten path so I really don't care about coverage. All I get is the occasional wrong number.

FWIW, the OP was not seen as negative by me but was informative.
