OnStar services help: Turn-by-Turn Navigation
What is Turn-by-Turn Navigation? OnStar Turn-by-Turn Navigation provides voice-guided driving directions to you in your vehicle over your speakers and uses Global Positioning System (GPS) technology to route you to your destination. Navigation is included for all Protect Plan Members traveling through our service areas. This covers approximately 98 percent of the U.S. population and approximately 80 percent of the population in Canada. How do I use Turn-by-Turn Navigation? To get directions, simply push the blue OnStar button and tell the Advisor where you want to go. Your Advisor will send detailed directions to the vehicle. These automated voice-guided directions take you to your destination with "turn tones," providing street names and distances to each turn along the way. The system even alerts you if you miss a turn and gives a revised route to the destination. You can also search destinations from your vehicle’s mobile app and send destinations to your navigation system. How do I adjust my route? You can easily modify your route with simple voice commands. Detailed instructions can be found on the Quick Reference Guide in your OnStar manual. Some popular commands: "Cancel route": Command to system to cancel receiving routes to a destination. "Route preview": Command to system to preview the route to destination. "Repeat": Command to system to repeat the last maneuver.
