The power of human connection

Text Box With / Without Heading

As the first to bring GPS satellite technology, Wi-Fi® and other innovative technologies to passenger vehicles, we have a long history with the connected car. But we’ve never forgotten that the most meaningful connections happen between people. And that’s why whenever you push your blue OnStar button, there’s a real live human being on the other end, ready to help. Here’s to the human connection.




A host of benefits to make your life easier and more secure.
