Disconnecting OnStar in Onstar-equipped 99-06 Silverados/Sierras
To kick Big Brother out of your truck, permanently, fuse removal is not enough, as that only disables audio functionality for OnStar. In Onstar-equipped 99-06 NBS trucks, the OnStar unit should be located behind the passenger side air bag and be accessible via the glove box. This simple, 5-step process will let you drive wherever you like, however you like -- without OnStar tracking it. You can undo this any time you like to re-enable OnStar; simply reverse the process.
Older (analog) OnStar units may not look like this or have the same number of connections, but the principle should be the same.
Also, if you plan to re-enable OnStar or want to reserve the ability to do so, then please pay attention which multi-pin ports on the OnStar unit your connections are using PRIOR to disconnecting them. You can see from the 4th picture, above, that there are more multi-pin ports than I have connectors. I will never re-attach mine so I didn't label anything. If you think you might want to reconnect yours, inspection prior to disconnection ... followed by labeling ... would be prudent.

Also worth mentioning is that the blue connector in the photos is for the GPS antenna (which makes it potentially re-usable for aftermarket GPS nav head-units) while the large coaxial-like connector is the cellular antenna (which is what's wound around your radio antenna ).
