AUDIO AND NAVIGATION SYSTEM 

LCD UNIT

A6E812466902T02

Outline

•

The car-navigation system LCD and the information display are incorporated into one unit. Based on signals 
from the car-navigation unit and remote control, the LCD displays navigational information. Based on signals 
from a specialized systems (audio, DIS and A/C) module, the LCD displays information about these systems 

•

The LCD unit senses the user operations from the remote control and sends a signal to the car-navigation unit.

Structure

•

An LCD unit, located in the upper-center part of the dashboard to improve visibility, has been adopted.

•

A pop-up LCD, controlled by an [OPEN/CLOSE] switch, has been adopted.

•

The angle of the display screen can be adjusted in stages using the [TILT] switch.

•

The audio, DIS and A/C information display is located on the lower portion of the unit. (See

AUDIO AND NAVIGATION SYSTEM 

REMOTE CONTROL AND CRADLE

A6E812400174T01

Outline

•

A remote control for the car-navigation system, with simplified design for easy operation, has been adopted.

•

A cradle to hold the remote control has been adopted.

Structure

•

The remote control and cradle are located on the console.

•

The buttons and joystick for controlling car-navigation are located on the top side of the remote control. The 
infrared transmitter sends signals through a terminal on the front and back of the remote control.

•

An infrared sensor that receives signals from the remote control is located on the cradle. The received signals 
are sent to the LCD unit.

•

The remote control uses the batteries as a power source when not in the cradle and uses the power supply 
connector when set in the cradle. (Ignition switch at ACC or ON position)

Note

•

The batteries are not charged when the remote control is in the cradle.

NAVIGATION FUNCTION

A6E812466000T06

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 DSC unit (with DSC) or ABS/TCS HU/CM (with ABS/TCS) 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, intersection, POI (Point of Interest), history, memory or 

map.

— Route information is available in map and guide mode.
— Voice guidance and menus are available in six languages.
— A map screen that displays maps in twelve steps with scales from 100m to 500km.
— A map screen that displays routes according to Shortest Route and Avoid Motorway functions.
— A detour function which provides three routes to select from based on streets selected to avoid, up to five 

via points and calculation of set detour distance.

— A wide variety of preferential settings are available.
