NAVIGATION SYSTEM
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 DVD-ROM,
which is stored in the DVD-ROM drive (map-matching), and indi-
cated on the screen as a current-loc ation mark. More accurate data
is judged and used by comparing vehicle position detecti on 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 selected because pr iorities 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 DVD-
ROM stored in DVD-ROM drive.
NOTE:
The road map data is based on data stored in the 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 th is case, the current-location mark on the display must be
corrected manually.

SEL684V
Type Advantage Disadvantage
Gyroscope (angular velocity sen-
sor) 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.

Self-Diagnosis Mode (DCU)
INFOID:0000000001328753
OPERATION PROCEDURE
1. Start the engine.
2. Turn the audio system OFF.
3. While pressing the “4” button, turn the volume control dial clock- wise or counterclockwise for 30 clicks or more. (When the self-
diagnosis mode is started, a short beep will be heard.)
 Shifting from current screen to previous screen is performed
by pressing “BACK” button.
Mode Description
Self Diagnosis (DCU)  Display control unit diagnosis
 Analyzes connection between the display control unit and each unit, and
operation of each unit.
Self Diagnosis (NAVI)  NAVI control unit diagnosis (DVD-ROM drive will not be diagnosed when
no DVD-ROM is in it.).
 Analyzes connection between the NAVI control unit and the GPS anten-
na.
Confirmation/
Adjustment Display Diagnosis
Color tone and shading of the display control unit-generated image can be
checked by the display of a color bar and a gray scale.
Vehicle Signals Diagnosis of signals that are input to display control unit can be performed
for Vehicle Speed, IGN, Reverse and Light.
Auto Climate Control Refer to AT C - 4 3 , "
Self-Diagnosis Function".
Navigation Display Diagnosis
Color tone and shading of the NAVI control unit-generated image can be
checked by the display of a color bar and a gray scale.
Vehicle Signals Diagnosis of signals that are input to NAVI control unit can be performed for
Vehicle speed, Lights, Ignition and Reverse.

gle
Adjustment
This mode is used to correct difference between actual turning angle of a
vehicle and turning angle of the vehicle mark on the display.
Speed
Calibration Under ordinary conditions, the navigation system distance measuring func-
tion will automatically compensate for minute decreases in wheel and tire
diameter caused by tire wear or low-pressure. Speed Calibration can im-
mediately restore system accuracy in cases such as when distance calibra-
tion is needed because of the use of tire chains.
Error History Malfunctions that occurred in the past are displayed, along with the number
of times each has occurred. Time and location when/where the errors oc-
curred are also displayed.
Delete Unit Connection Log Erase the connection history of unit and error history.
CAN DIAG SUPPOPT MONITOR The transmitting/recei ving of CAN communication can be monitored.
