Every day, millions of OnStar Members count on OnStar to be there whenever they need it — whether it’s getting directions with Turn-by-Turn Navigation,*11 connecting with friends and family, or getting help if they’re in a crash. We’ve worked for more than two decades to make driving easier, safer and better for our Members, and in large part, that’s because we’ve listened to what they’ve told us.

We’ve collected some of their stories, so you can learn about how they use OnStar and how it’s helped them. We’ve also put together some tips to help you get the most out of your services.

There’s a lot about OnStar that you may not know. But we’d love to show you how it works. Read on to find out more.
