NAVIGATION SYSTEM
Location 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.

DIAGNOSIS SYSTEM (NAVI CONTROL UNIT)
Diagnosis DescriptionINFOID:0000000001728643
MULTI AV SYSTEM on board diagnosis function
 The NAVI control unit diagnosis function starts up with audio switch operation and the NAVI control unit per-
forms 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 NAVI control unit, connections between system compo-
nents as well as connections between NAVI control unit and GPS 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).
On board diagnosis item
STARTING PROCEDURE
1. Start the engine.
2. Turn the audio system OFF.
Mode Description
Self Diagnosis NAVI control unit diagnosis
 Diagnoses the connections across system components, between
NAVI control unit and GPS antenna.
Confirmation/
AdjustmentDisplay DiagnosisThe following check functions are available: color tone check by color
bar display, light and shade check by gray scale display.
Vehicle SignalsDiagnosis of signals can be performed for vehicle speed, parking
brake, lights, ignition switch, and reverse.
Speaker Test The connection of a speaker can be confirmed by test tone.
NavigationSteering Angle Ad-
justmentA difference can be adjusted between the actual turning angle and the
vehicle mark turning angle.
Speed CalibrationA difference can be adjusted between the current location mark and the
actual location.
Error HistoryThe system malfunction and the frequency when occurred in the past
are displayed. The time and place that the selected malfunction last oc-
curred are displayed when the malfunctioning item is selected.
Vehicle CAN Diagnosis The transmitting/receiving of CAN communication can be monitored.
AV COMM DiagnosisThe communication condition of each unit of Multi AV system can be
monitored.
Handsfree PhoneThe received volume adjustment of hands-free phone, microphone
speaker check, and erase memory can be performed.
Bluetooth The passkey and the device name can be checked and changed.
Delete Unit Connection Log Erase the connection history of unit and error history.
Feature Restriction SettingOperations of navigation system while driving can be restricted by us-
ing this function.

3. Turn the volume control dial clockwise or counterclockwise for
40 clicks or more while pushing the “SETTING” button. (A short
beep will be heard when the self-diagnosis mode is started.)
 Shifting from current screen to previous screen is performed
by pushing “BACK” button.
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. Then 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 subdivi-
sion screen indicates progress of the trouble 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:
 Only the control unit (NAVI control unit) is displayed in red.
- The screen switch colors are determined according to the following order of priority: red > yellow > gray if
multiple errors occur at the same time for a single unit.

- The comments of the self-diagnosis results can be viewed with a
component in the diagnosis result screen.
Detection range of self-diagnosis mode
 The self-diagnosis mode allows the technician to diagnose the connection in the communication line
between NAVI control unit and each unit and the internal operation of the NAVI 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 a switch.
Self-diagnosis results
Check the applicable display at the following table, and then repair the malfunctioning parts.

STEERING ANGLE ADJUSTMENT
The steering angle output value detected with the gyroscope is
adjusted.
SPEED CALIBRATION
During normal driving, distance error caused by tire wear and tire
pressure change is automatically adjusted for by the automatic dis-
tance correction function. This function, on the other hand, is for
immediate adjustment, in cases such as driving with tire chain fitted
on tires.
ERROR HISTORY
The diagnostic results of “Self-diagnosis” determine if any malfunction occurred between selecting “Self-diag-
nosis” and displaying “Self-diagnostic Results”.
The trouble diagnosis result will be judged normal if an error occurred before the ignition switch was turned
ON and does not occur again until “Self-diagnosis” is completed. Therefore, errors in the past which cannot be
found by “Self-diagnosis”, must be found by checking the “Error record”.
The error history shows the error occurrence frequency in past. The frequency of occurrence is displayed by 2
types: the count down type and the count up type. Select either type according to the error item.
In “Error History” of models with NAVI, time and place that the selected error last occurred are displayed. Be
careful about the following.
 The correct date of occurrence may not be able to be displayed if there is a malfunction with the GPS
antenna circuit board in the NAVI control unit.
 Place of the error occurrence is represented by the position of the current location mark at the time an error
occurred. If current location mark has deviated from the correct position, then the place of the error occur-
rence cannot be located correctly.Tweeter : 3 kHz

Count Down Type
 Set the counter to 40 when the error is detected. The counter decreases by 1 if the system is normal when
turning the ignition switch ON.
 The lower limit of the counter is 1. It can be reset to 0 by “Delete log” switch or CONSULT-III.
Count Up Type The counter increases 1 when the ignition switch is turned ON and the error is detected. The counter does
not decrease even if it is normal when the ignition switch is turned ON the next time.
 The upper limit of the counter is 50. 51 or more is displayed as 50. It can be reset to 0 by “Delete log” switch
or CONSULT-III.
Error Item Some error items may be displayed simultaneously according to the cause. The detection of the cause can
be performed by the combination of display items if some error items are displayed simultaneously.
