Differences between the Onstar Guardian app and the My GMC app ??

New Contributor II

What is the difference between the My GMC app and the Ontar Guardian app ?? And why would you need or want both ??



The Guardian app allows you to take the safety and security of key OnStar services wherever you go (OnStar Guardian offers Mobile Crash Response, which uses smartphone sensors to detect a crash and alert an Emergency-Certified Advisor, 24/7 Roadside Assistance, Location Status and Emergency Services). 

The myGMC mobile app helps simplify your ownership experience by connecting you with your vehicle’s connected services. For example, depending on your service plan and vehicle capabilities, you may be able to remotely start or stop your vehicle, lock or unlock its doors, see your vehicle’s location on a map, set boundary notifications, view your vehicle’s fuel level or oil life, monitor your vehicle’s health and more. Moving forward, if you have any questions regarding either mobile app, we are more than happy to help. Kindly send us an email to with 'ATTN: OnStar Community/JWP' in the subject line.
