Navigation System

The navigation system provides detailed maps of most major freeways and roads throughout the United States and Canada. After a destination has been set, the system provides turn-by-turn instructions for reaching the destination. In addition, the system can help locate a variety of POIs (Points of Interest), such as banks, airports, restaurants, and more.

See Using the Navigation System   for more information.
