Function
Navigation function
Calculates route to destination, and provides guidance using the settings made by the user.
The navigation system is a hybrid-type system which combines independent navigation and satellite navigation to provide highly accurate detection of the current position based on specialized map matching which identifies the current position by comparing the map information data read from the navigation map data on the SD card with the current position measured by the independent navigation and satellite navigation systems.
Map matching
Map matching compares the road configurations of the map information data stored in the SD based on the current position information measured from independent navigation and satellite navigation, and corrects the current position to the most suitable map information data on the route.
Guidance
The remaining distance to destination, branch points, and road names are indicated on the display.
Voice guidance is provided for destination, distance to branch point and heading. The voice guidance is output from the speakers equipped on the vehicle.
Structural view
The car-navigation system consists of the car-navigation unit, audio unit, command switch, GPS antenna, voice recognition microphone, and speakers.
