How to Disable GPS Onstar

OnStar allows vehicles to be tracked after a crash or theft.

OnStar is a feature included on many General Motors vehicles. The service uses Global Positioning System (GPS) information to operate. Cars with OnStar enabled can be located after a crash or theft, and drivers may communicate with OnStar personnel for information such as directions. Some owners, however, prefer not to allow their vehicle to be tracked. Completely removing the OnStar module means that no location data can be sent, ensuring privacy but also disabling the safety features of the service.

Things You'll Need

• Basic hand tools

Remove OnStar Module

1. Open the trunk or rear storage area of the vehicle. Locate the area that holds the spare tire and remove the storage cover. Unscrew any bolts holding the spare tire and tire cover in place, and pull these items out of the way.

2. Remove the recessed plastic plate behind the tire storage area. Several screws may hold it in place. With the plastic plate out of the way, slide the right-hand side of the fabric lining out of the way. The OnStar unit should be located here. This is a black box connected to a signal cable.

3. Remove the signal cable that connects to the OnStar device. Disconnect the device itself by unscrewing the mounting screws holding it in place. Once it is unscrewed from the side panel, it can be removed from the vehicle. Replace the lining and plastic covering in the storage compartment when finished.

Tips & Warnings

• The exact location of the OnStar unit will vary depending on the model of vehicle. However, it is almost always in the cargo area placed under a removable plastic liner.

• All OnStar safety features, including location tracking and emergency voice contact, will be disabled once the OnStar unit is removed. Removing the unit may also void the manufacturer's warranty.
