How To Disable OnStar?

[steve45]

When I got my company truck, I asked a technician at the dealer how to disable the OnStar system. He didn't know, but suggested just unplugging the antenna. There doesn't appear to be a separate fuse for just the OnStar system.

My company works with explosives, and having the OnStar transmitter onboard means that I have to park a considerable distance from where the work is taking place. If I could turn the system off, it would make life a lot easier.

Thanks!

it is behind the radio under the heater controls in the dash just disconnect the power harness, disconnecting the gps antenna only disables gps the cellular will still be active, you have to unplug the power harness.
this video shows you were it is, just do the opposite of what he did and unplug the power harness should be black one with 6 or 8 wires
