SYSTEM DESCRIPTION
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:
TheroadmapdataisbasedondatastoredinthemapDVD-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.
lIn 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 vehicle 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 vehicle mark may appear on either of them alter-
nately, depending on maneuvering of the steering wheel and
configuration of the road.
lMap-matching does not function correctly when a road on which
the vehicle is driving is new and not recorded in the map 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 vehicle mark
on it. Then, when the correct road is detected, the vehicle mark
may change to it.
lEffective range for comparing the vehicle position and travel
direction calculated by the distance and direction with the road
data read from the map 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.

SYSTEM DESCRIPTION
Component Description
EKS00Q5Y
AUDIO UNIT
Perform AUDIO operation by AV SWITCH for models with navigation system.
NAVI CONTROL UNIT
lThe gyro (angular speed sensor) and the DVD-ROM drive are
built-in units that control the navigation functions.
lSignals are received from the gyro, the vehicle speed sensor,
and the GPS antenna. Vehicle location is determined by com-
bining this data with the data contained in the DVD-ROM map.
Locational information is shown on liquid crystal display panel.
DVD-ROM Drive
lDVD loading slot (1)
Maps, traffic control regulations, and other pertinent information can
be easily read from the DVD-ROM disc.
Map DVD-ROM
lThe map DVD-ROM has maps, traffic control regulations, and other pertinent information.
lTo 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)
lThe oscillator gyro sensor is used to detect changes in vehicle steering angle.
lThe gyro is built into the navigation (NAVI) control unit.

Navigation System Diagnosis FunctionEKS00Q6H
lThere are 2 diagnosis functions (on board diagnosis and diagnosis using CONSULT-II), and it is neces-
sary to use them properly according to the condition. If the on board diagnosis starts, perform diagnosis
with on board diagnosis. If the on board diagnosis does not start (the cause being that the system is not
started, the switch operation is not activated, etc.), perform diagnosis using CONSULT-II.
lAt on board diagnosis, the NAVI control unit diagnosis function starts by switch operation and the NAVI
control unit performs the diagnosis for each unit of system.
lAt diagnosis using CONSULT-II, the NAVI control unit diagnosis function starts by the communication
between CONSULT-II and NAVI control unit, and the NAVI control unit performs the diagnosis for each
unit of system.
On Bord Self-Diagnosis FunctionEKS00Q6I
DESCRIPTION
lThe on board diagnosis function has a self-diagnosis mode for performing trouble diagnosis automatically
and a Confirmation/Adjustment mode for operating manually.
lSelf-diagnosis mode performs the diagnosis at NAVI control unit, connections between each unit that
composes the system, and connections between NAVI control unit and GPS antenna. It displays the
results on the display.
lConfirmation/Adjustment mode is used to monitor the vehicle signals requiring operation and judgement
by a technician (malfunctions that cannot be automatically judged by the system), the confirmation/adjust-
ment of setting value, the error history of system, and the communication condition of system.
DIAGNOSIS ITEM
Mode Description
Self Diagnosis
lNAVI control unit diagnosis (DVD-ROM drive will not be diagnosed when
no map DVD-ROM is in it.)
lThe connection diagnosis between NAVI control unit and GPS antenna
and the connection diagnosis between NAVI control unit and each unit
can be performed.
Confirma-
tion/Adjust-
mentDisplay DiagnosisThe tint can be confirmed by the color spectrum bar display. The shading
of color can be confirmed by the gradation bar display.
Vehicle SignalsDiagnosis of signals can be performed for vehicle speed, parking brake,
lights, ignition (ignition switch), and reverse.
Speaker Test The connection of a speaker can be confirmed by test tone.
NavigationSteering Angle
AdjustmentWhen there is a difference between the actual turning angle and the vehi-
cle mark turning angle, it can be adjusted.
Speed CalibrationWhen there is a difference between the current location mark and the
actual location, it can be adjusted.
Error HistoryThe system malfunction and its frequency that occurred in the past are dis-
played. When the malfunctioning item is selected, the time and place that
the selected malfunction last occurred are displayed.
Vehicle CAN Diagnosis The transmitting/receiving of CAN communication can be monitored.
AV COMM DiagnosisThe communication condition of each unit that composes the system can
be monitored.
Handsfree PhoneEach setting of hands-free volume adjustment, voice microphone test,
delete hands-free memory can be performed.
Bluetooth Passkey and device name can be confirmed/changed.
Delete Unit Commection Log The connection history and error history of unit can be deleted.

1. Start the diagnosis function, and then select “Self Diagnosis”.
–Self-diagnosis screen is displayed. The system enters in the self-diagnosis mode.
–The bar graph visible on the center of screen indicates the
progress of self-diagnosis.

plete. Each unit name and connection lines between each unit
will be colored according to the diagnostic results, as follows.
* : Only control unit (NAVI control unit) is displayed in red.
NOTE:
lSwitch: AV switch
lControl unit: NAVI control unit
lAmplifier is built in Audio unit.
–If multiple malfunctions occur at the same time for a single unit, the screen switch colors are determined
according to the following order of priority: red > yellow > gray.
–When selecting the screen switch on self-diagnosis screen, the
comment of self-diagnosis results is displayed.
