Stick the key in ignition and start the engine it will interrupt the radio and say "phone not available", take the key out after turing off same thing, open a door after stopping same thing. HELP ME it is driving me crazy. I talked to onstar tech support and they told me to disconnect battery which I did and it did not correct problem. Anybody????? HELP
TAKE IT TO A DEALER THEY WILL DEACTIVATE IT FOR YOU. THERE IS A SPECIAL POLICY FOR ONSTAR DEACTIVATION. IT SHOULDN'T COST YOU ANYTHING.

Lift up the floor mat on the bottom of the trunk. You will see your spare tire, jack and OnStar unit. Unscrew the top of the OnStar unit, using a Phillips screwdriver.
Remove the lid from the top of the OnStar unit box; you will see three white plastic cables running from the OnStar box to your vehicle.
Unplug the three cables from the OnStar unit to disconnect them.
