What is Onstar?

Keeping You Connected for the Road Ahead


When OnStar was released in 1996, technological innovations like smartphones and in-dash nav systems didn’t exist. But we imagined something different: a truly connected world, where drivers always had a real person there for them.

Today, OnStar is celebrating 20 years of impacting lives — helping nearly 10 million people get the assistance they needed, even when they couldn’t ask for it themselves. We were the first to bring satellite technology, Wi-Fi®1 and other innovative services to passenger vehicles. And we’re still driven by the same passion that led us to the forefront of the connected car revolution two decades ago, because we never forgot that the most meaningful connections happen between people. Together, we can do amazing things.
