Navigation System
If the vehicle has a navigation system, there is a separate navigation system manual that includes information on the radio, audio players, and navigation system.
The navigation system provides detailed maps of most major freeways and roads. 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 points of interest (POIs), such as banks, airports, restaurants, and more.
See the navigation system manual for more information.
