Description

• 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.

SYSTEM

• In map-matching, alternative routes to reach the destination will be

shown and prioritized, after the road on which the vehicle is cur-

rently driven has been judged and the vehicle mark has been repo-

sitioned.

Alternative routes will be shown in different order of priority, and

the incorrect road can be avoided if there is an error in distance

and/or direction.

They are of the same priority if two roads are running in parallel.

Therefore, the vehicle mark may appear on either of them alter-

nately, depending on maneuvering of the steering wheel and con-

figuration of the road.

• Map-matching does not function correctly when a road on which

the vehicle is driving is new and not recorded in the map SD card,

or when road pattern stored in the map data and the actual road

pattern are different due to repair.

The map-matching function may find another road and position the

vehicle mark on it when driving on a road not present in the map.

Then, the vehicle mark may change to it when the correct road is

detected.

• Effective range for comparing the vehicle position and travel direc-

tion calculated by the distance and direction with the road data

read from the map SD card is limited. Therefore, correction by

map-matching is not possible when there is an excessive gap

between current vehicle position and the position on the map.

GPS (Global Positioning System)

GPS (Global Positioning System) is developed for and is controlled

by the US Department of Defense. The system utilizes GPS satel-

lites (NAVSTAR), transmitting out radio waves while flying on an orbit

around the earth at an altitude of approximately 21,000 km (13,049

mile).

The receiver calculates the travel position in three dimensions (lati-

tude/longitude/altitude) according to the time lag of the radio waves

that four or more GPS satellites transmit (three-dimensional position-

ing). The GPS receiver calculates the travel position in two dimen-

sions (latitude/longitude) with the previous altitude data if the GPS

receiver receives only three radio waves (two-dimensional position-

ing). GPS position correction is not performed while stopping the

vehicle.

Accuracy of the GPS will deteriorate under the following conditions:

• In two-dimensional positioning, GPS accuracy will deteriorate when altitude of the vehicle position changes.

• The position of GPS satellite affects GPS detection precision. The position detection may not be precisely

performed.

• The position detection is not performed if GPS receiver does not receive radio waves from GPS satellites.

(Inside a tunnel, parking in a building, under an elevated highway etc.) GPS receiver may not receive radio

waves from GPS satellites if any object is placed on the GPS antenna.

NOTE:

• The detection result has an error of approximately 10 m (32.81 ft) even with a high-precision three dimen-

sional positioning.

• There may be cases when the accuracy is lowered and radio waves are stopped intentionally because the

GPS satellite signal is controlled by the US trace control center.

AUXILIARY INPUT FUNCTION

• Sound can be output from an external device by connecting a device with USB connector and AUX jack.

• AUX sound signals are transmitted to each speaker via NAVI control unit.

USB CONNECTION FUNCTION

• iPod

®

 or music files in USB memory can be played.

®

.

• Operation is performed by steering switch.

• Guide sound that is heard during operation is output from NAVI control unit to front speaker.

AROUND VIEW MONITOR FUNCTION

• This system is equipped with wide-angle cameras on the front and rear of the vehicle and on both right and

left door mirrors. The images from front view, rear view, front-side view (RH side), and birds-eye view that

shows the view from the top of the vehicle are displayed to monitor the vehicle surroundings. 

• Around view monitor control unit cuts out and expands the image received from each camera to create each

view. 

• In front view and rear view, the vehicle width, distance lines and predictive course lines are superimposed

and displayed. In front-side view, the vehicle distance guiding line and vehicle width guiding line are dis-

played. 

• The Birds-Eye view converts the images from 4 cameras into the overhead view and displays the status of

the vehicle on display. The vehicle icon that are displayed on the Birds-Eye view display are rendered by

around view monitor control unit. 

• Moving Object Detection (MOD) is adopted that detects moving objects according to camera image and noti-

fies the detection result to the driver.

Around View Monitor Screen

• Around view monitor combines and displays the travel direction view and “Birds-Eye view”, “Front-Side

view”.

• Around view monitor control unit renders the view icon and warning message on display. Warning messages

are displayed in the language set at the Navigation System settings.

Screen constitution

Operation Description

• Around view monitor operates by pressing the “CAMERA” switch or shifting the selector lever to the reverse

position. 

• When the selector lever is in any position other than the reverse position, the screen is switched to the

around view monitor by pressing the “CAMERA” switch.
