When I bought my 2009 HHR SS, I made sure the dealer did not activate the complimentary subscription.
I got the standard fear mongering letters for a couple months before I decided on a more permanent solution.... there was a nice big fuse marked "ON STAR"... problem solved, box has no power it can't do anything.
Luckily on that particular car, I didn't lose any functionality that I cared about... the OnStar box provided Bluetooth for the phone and XM radio, neither features that I cared about.
Shortly after I pulled the fuse, I received one more letter from GM that stating that my vehicle had stopping checking in to the OnStar system, and I should have it serviced immediately." :ughlaugh:
I can understand why people may want this service, but I don't understand why it has to mandatory. Well... I do understand... think of the value of the data.
