OnStar Turn-by-turn Naviation
Available on most 2007 GM vehicles, OnStar Turn-by-Turn Navigation is a unique and easy-to-use navigation service included in the award-winning Directions & Connections Plan. This system is fully integrated with your vehicle and your OnStar services.
Simple, Smart + Safe
The enhanced GPS system guides you turn-by-turn to your destination and automatically helps you get back on track if you make a wrong turn. With its one button push operation, OnStar Turn-by-Turn navigation is the simplest navigation system. Stay safely focused on the road as you follow the automated voice-guided directions and simple text-based information.
How It Works
The safe and easy way to get to your destination — at the touch of a button. All it takes is four easy steps.
- PUSH your blue OnStar button and you'll be connected to a live Advisor.
- TELL OnStar where you need to go and turn-by-turn directions will be downloaded to your vehicle.
- LISTEN to the voice-guided directions after the Advisor disconnects from your vehicle.
- ARRIVE at your destination.
