NAVIGATION SYSTEM
NAVIGATION SYSTEM
System DiagramINFOID:0000000003765835
System DescriptionINFOID:0000000003765836
DESCRIPTION
 The navigation system can be operated by display (touch panel), multifunction switch or steering switch.
Each operation signal is input to AV control unit. AV control unit communicates with NAVI control unit via AV
communication, and controls the navigation system.
 Guide sound during the operation of the navigation system is output from NAVI control unit to front speaker
through AV control unit and BOSE amp.
 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 DVD-ROM. It transmits the map image
signal (RGB image, RGB area, and the synchronizing RGB image) to display through AV 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 DVD-
ROM, which is stored in the DVD-ROM drive (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
DVD-ROM stored in DVD-ROM drive.
NOTE:
The road map data is based on data stored in the map DVD-ROM.
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. In this case, the vehicle mark on the display must be cor-
rected manually.
 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.

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.

CAMERA IMAGE OPERATION PRINCIPLE
 Power is supplied to rear view camera from camera control unit and the rear view camera outputs the cam-
era image to camera control unit when selector lever is set to reverse position and the reverse signal on
camera control unit is input.
 Camera control unit superimposes the guiding line and predicted course line to the image from rear view
camera and outputs to display unit. In this case, the reverse signal is also input to AV control unit. Therefore,
AV control unit recognizes the selector lever as in the reverse position. And then AV control unit switches the
image displayed by the communication signal between AV control unit and display unit with the camera
image.
 AV control unit outputs camera image signal that is inputted from camera control unit to display unit.
 Camera control unit controls the direction and distance of predicted course line according to the sensor sig-
nal from steering angle sensor.
 AV control unit determines whether rear view camera is equipped or not, based on the presence of camera
connection recognition signal. It switches to rear view monitor image at the time of reverse signal input when
rear view camera is equipped.

Diagnosis DescriptionINFOID:0000000003765847
MULTIFUNCTION SWITCH AND PRESET SWITCH SELF-DIAGNOSIS FUNCTION
The on/off operation (continuity) of each switch in the multifunction switch and preset switch can be checked.
Self-Diagnosis Mode
 Press the “back” switch and the “up” switch of the 8-direction
switches within 10 seconds after turning the ignition switch from off
to ACC and hold them for 3 seconds or more. then the buzzer
sounds, all indicators of the preset switch illuminate, and the self-
diagnosis mode starts.
 The continuity of each switch at the on position can be checked by
pressing the switch. the buzzer sounds if the switch is normal.
NOTE:
The hazard switch and disk eject switch cannot be checked.
Finishing Self-diagnosis Mode
Self-diagnosis mode is canceled when turning the ignition switch off.
MULTI AV SYSTEM ON BOARD DIAGNOSIS FUNCTION
 The AV control unit diagnosis function starts up with multifunction switch operation and the AV control unit
performs a diagnosis for each unit in the system during the on board diagnosis.
 Perform a CONSULT-III diagnosis if the on board diagnosis does not start, e.g., the screen does not display
anything, the multifunction switch does not function. etc.
ON BOARD DIAGNOSIS
Description
 The trouble diagnosis function has a self-diagnosis mode for conducting trouble diagnosis automatically and
a confirmation/adjustment mode for operating manually.
 The self-diagnosis mode performs diagnoses on the AV control unit and NAVI control unit, connections
between system components as well as connections between NAVI control unit and GPS antenna and
between NAVI control unit and TEL antenna. Then it displays the diagnosis results on the display.
 The confirmation/adjustment mode allows the technician to check, modify or adjust the vehicle signals and
set values, as well as to monitor the system error records and system communication status. The check,
modify or adjust actions generally require human intervention and judgment (the system cannot make judg-
ment automatically.

4. The trouble diagnosis initial screen is displayed, and then the
items of “Self Diagnosis” and “Confirmation/Adjustment” can be
selected.
SELF-DIAGNOSIS MODE
1. Start the self-diagnosis function and select “Self Diagnosis”.
- Self-diagnosis subdivision screen is displayed, and the self-diagnosis mode starts.
- The bar graph visible on the center of the self-diagnosis subdivision screen indicates progress of the trou-
ble diagnosis.
2. Diagnosis results are displayed after the self-diagnosis is com-
pleted. The unit names and the connection lines are color-coded
according to the diagnostic results.
NOTE:
 In case of connection malfunction of GPS or TEL antenna, diagnosis result follows “unit malfunction”
way to display.
 Replace AV control unit if “Self-Diagnosis did not run because of a control unit malfunction” is indicated.
The symptom is AV control unit internal error. Refer to AV-648, "
Exploded View".
- The comments of the self-diagnosis results can be viewed with a
component in the diagnosis result screen.
SELF-DIAGNOSIS RESULTS
 Check the applicable display at the following table, and then repair the malfunctioning parts.
 The self-diagnosis mode allows the technician to diagnose the connection in the communication line
between AV control unit and each unit and the internal operation of the AV control unit.
 Because the start condition of diagnosis function is a switch operation, the on board diagnosis function can-
not be started up if any malfunction is detected in the communication circuit between AV control unit and
multifunction switch.
