Vehicle Update

We appreciate your outreach. After you purchase a GMC vehicle equipped with OnStar, all you need to do is push the blue OnStar button in your vehicle to activate services. Be sure you have power to the vehicle and that it is stationary and parked. From there, an enrollment advisor will be happy to assist you with setting up an account and enrolling you in an OnStar plan that best fits your needs or adding your new vehicle to your current, active account. Please let us know if you have additional questions. We are happy to help.
