Removal and Installation of Audio Unit (Base system)NKS002BH
REMOVAL
1. Remove cluster lid C. Refer to IP-10, "INSTRUMENT PANEL ASSEMBLY" .
2. Remove screws (A), and remove audio unit (1).
3. Remove screws (8), and remove bracket.
INSTALLATION
Installation is the reverse order of removal.
Locking CD Auto Changer Mechanism (Audio unit of BOSE system)NKS002BI
CAUTION:

Prior to removing a malfunctioning CD auto changer unit (Audio unit of BOSE system) that will be
shipped for repair, the changer mechanism MUST BE LOCKED to prevent the mechanism from
being damaged during shipping.

If a CD is jammed or unable to be removed from the unit, do NOT lock the changer mechanism. If
the unit is to be shipped for repair, carefully package the unit to prevent vibration and shock.
DAMPER LOCK PROCEDURE
1. Eject and remove any CDs from the audio unit (BOSE system).
2. Turn ignition switch OFF. Wait until audio unit (BOSE system) display is off and mechanism stops moving
(mechanism sound stops).
3. Press any one of the disc selection buttons once. When a display shows on the audio unit (BOSE sys-
tem), press the same disc selection button again within 5 seconds.

The changer mechanism will lock itself within 10 seconds.
4. After mechanism stops moving (mechanism sound stops), open the driver and passenger window, and
then disconnect negative battery cable.
CAUTION:
After the battery cables are disconnected, do not open/close the driver and/or front passenger door
with the window in the full up position. The automatic window adjusting function will not work and the
side roof panel may be damaged.
NOTE:
After installing a new or remanufactured audio unit (BOSE system), switching the audio unit (BOSE system)
ON will automatically unlock the mechanism. A special unlocking procedure is not required.

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 this case, the current-location mark on the display must be
corrected manually.

In map-matching, alternative routes to reach the destination will
be shown and prioritized, after the road on which the vehicle is
currently driven has been judged and the current-location mark
has been repositioned.
If there is an error in distance and/or direction, alternative routes
will be shown in different order of priority, and the incorrect road
can be avoided.
If two roads are running in parallel, they are of the same priority.
Therefore, the current-location mark may appear on either of
them alternately, depending on maneuvering of the steering
wheel and configuration 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 DVD-ROM,
or when road pattern stored in the map data and the actual road
pattern are different due to repair.
When driving on a road not present in the map, the map-match-
ing function may find another road and position the current-loca-
tion mark on it. Then, when the correct road is detected, the
current-location mark may change to it.

Effective range for comparing the vehicle position and travel
direction calculated by the distance and direction with the road
data read from the DVD-ROM is limited. Therefore, when there
is an excessive gap between current vehicle position and the
position on the map, correction by map-matching is not possible.

Component DescriptionNKS002QA
NAVI CONTROL UNIT

NAVI control unit connects to the display unit and NAVI switch
with communication lines.

The gyro (angular speed sensor) and the DVD-ROM drive are
built-in units that control the navigation functions.

Signals are received from the gyro, the vehicle speed sensor,
and the GPS antenna. Vehicle location is determined by com-
bining these data with the data contained in the DVD-ROM map.
Locations information is shown on display unit.

NAVI control unit outputs ON signal and voice guidance signal to
audio unit.
DVD-ROM Drive
Maps, traffic control regulations, and other pertinent information can
be easily read from the DVD-ROM (1).
DVD-ROM

The DVD-ROM has maps, traffic control regulations, and other pertinent information.

To improve DVD-ROM map matching and route determination functions, the DVD-ROM uses an exclusive
Nissan format. Therefore, the use of a DVD-ROM provided by other manufacturers cannot be used.
Gyro (Angular Speed Sensor)

The oscillator gyro sensor is used to detect changes in vehicle steering angle.

The gyro is built into the NAVI control unit.
GPS ANTENNA
The GPS antenna receives and amplifies the radio waves from the
GPS satellites, and then transmits the GPS signal to NAVI control
unit.

DISPLAY UNIT

Display unit connects to the NAVI control unit and NAVI switch
with communication lines.

Display unit receives RGB image signal from NAVI control unit,
and RGB image is displayed.
NAVI SWITCH

NAVI switch connects to the display unit and NAVI control unit
with communication lines.

Operation signal from NAVI switch is transmitted to NAVI control
unit through display unit.

Special Note for Trouble DiagnosisNKS002JP
Prior to perform trouble diagnosis, make sure there are no corresponding description in the “Example of
Symptoms Possible No Malfunction”. Refer to AV- 9 5 , "
Example of Symptoms Possible No Malfunction" .
On Board Self-Diagnosis FunctionNKS000D6
DESCRIPTION

Trouble diagnosis function of navigation system has a Self Diagnosis mode by automatic operation and a
Confirmation/Adjustment mode by manual operation.

Self Diagnosis mode checks for connections between the units constituting this system, analyzes each
individual unit at the same time, and displays the results on the display unit.

Confirmation/Adjustment mode displays trouble diagnosis that require an operation and a judgment by a
human (auto-decision can not be performed by the system), confirmation of preset value, and an error his-
tory.
DIAGNOSIS ITEM
Self Diagnosis ModeNKS000D7
OPERATION PROCEDURE
1. Start the engine.
2. Press and hold “MAP” and “ ” buttons simultaneously for 5
seconds or more.

Shifting from current screen to previous screen is performed
by pressing “BACK” button.
Mode Description
Self Diagnosis

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 antenna, con-
nection between the NAVI control unit and each unit, and operation of each unit.
Confirmation/
AdjustmentDisplay DiagnosisColor tone and shading of the screen can be checked by the display of a color bar
and a gray scale.
Vehicle SignalsDiagnosis of signals that are input to NAVI control unit can be performed for Vehicle
speed, Lights, Ignition and Reverse.
NavigationSteering Angle
AdjustmentThis mode is used to correct difference between actual turning angle of a vehicle
and turning angle of the vehicle mark on the display.
Speed CalibrationUnder ordinary conditions, the navigation system distance measuring function will
automatically compensate for minute decreases in wheel and tire diameter caused
by tire wear or low-pressure. Speed Calibration can immediately restore system
accuracy in cases such as when distance calibration is needed because of the use
of tire chains.
Error HistoryMalfunctions that occurred in the past are displayed, along with the number of times
each has occurred. Time and location when/where the errors occurred are also dis-
played.
