• The navigation system can be operated by control panel of the NAVI control unit and display (touch panel) of

the NAVI control unit.

• Guide sound during the operation of the navigation system is output from NAVI control unit to front speaker.
• NAVI control unit calculates the vehicle location based on the signals from GYRO (angle speed sensor),

vehicle sensor, and GPS satellite, as well as the map data from map SD card. It is displayed on display of
the NAVI control unit.

POSITION DETECTION PRINCIPLE

The navigation system periodically calculates the vehicle's current position according to the following three
signals:
• Travel distance of the vehicle as determined by the vehicle speed sensor
• Turning angle of the vehicle as determined by the gyroscope (angular velocity sensor)
• Direction of vehicle travel as determined by the GPS antenna (GPS information)
The current position of the vehicle is then identified by comparing the calculated vehicle position with map data
read from the map SD card (map-matching), and indicated on the screen as a vehicle mark. More accurate
data is judged and used by comparing vehicle position detection results found by the GPS with the result by
map-matching.

The current vehicle position will be calculated by detecting the dis-
tance the vehicle moved from the previous calculation point and its
direction.
• Travel distance

Travel distance calculations are based on the vehicle speed sen-
sor input signal. Therefore, the calculation may become incorrect
as the tires wear down. To prevent this, an automatic distance cor-
rection function has been adopted.

• Travel direction

Change in the travel direction of the vehicle is calculated by a gyro-
scope (angular velocity sensor) and a GPS antenna (GPS informa-
tion). They have both advantages and disadvantages.

More accurate traveling direction is detected because priorities are set for the signals from these two
devices according to the situation.

MAP-MATCHING

Map-matching compares a current location detected by the method
in the “Location Detection Principle” with a road map data from map
SD card.
NOTE:
The road map data is based on data stored in the map SD card.

The vehicle position may not be corrected under the following circumstances and after driving for a certain
time when GPS information is difficult to receive.

Type

Advantage

Disadvantage

Gyroscope
(angular velocity sensor)

Can detect the vehicle's turning angle quite 
accurately.

Direction errors may accumulate when vehicle is 
driven for long distances without stopping.

GPS antenna
(GPS information)

Can detect the vehicle's travel direction 
(North/South/East/West).

Correct direction cannot be detected when vehicle 
speed is low.
