I can see where some could use/need it. I'm just givin' you buttheads a hard time. The way I understand it, you have to pay the On-Star subscription and the wi-fi runs an extra $5 for every 200 MB. I believe you get something like a 90-day free trial with the new car. We have the same on our new 'Yota with Sirius ... sumpin' we don't really need.
