NAVIGATION FUNCTION

Outline
A vehicle's position is measured by a hybrid method of autonomous navigation (using yaw-rate signals from the
gyro sensor and vehicle speed signals from the instrument cluster) and GPS navigation (using signals from
GPS satellites). Accurate detection of the vehicle's position is possible based on the adoption of a map-
matching function which specifies the vehicle's position as compared with the map data read from the DVD-
ROM and the vehicle's position measured from autonomous navigation and GPS navigation.
Guidance to destination is provided via display of the recommended route on the map screen, as well as voice
messaging guidance at intersections and points of divergence.
Based on inputted signals and information on the DVD-ROM, the following features are available:
— Destination can be selected based on address, POI (Point of Interest), emergency, memory point, home,
preset destination, intersection, freeway on/off ramp, coordinates, map or previous destination.
— Route information is available in map, turn list, turn arrow, enlarged junction diagram, freeway information
mode.
— Voice guidance and menus are available in three languages.
— A map screen that displays maps in thirteen steps with scales from 50 m to 256 km {1/32 mile to 128 mile}.
— A map screen that displays routes according to search condition (info) and route preferences.
