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.

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.
Delete Unit Connection Log Erase the connection history of unit and error history.

Steering Angle Adjustment
The steering angle output value detected by the gyroscope can be
adjusted.
Speed Calibration
Usually the automatic distance correction function adjusts the mal-
function in distance caused by the tires wearing down or the tire
pressure change. If prompt adjustment is necessary when the tire
chains are installed etc., perform this procedure.

HANDS-FREE PHONE SYSTEM

For Hands-free phone system operation information, refer to Owner's Manual.

TEL adapter unit has Bluetooth® module. It can perform wireless hands-free telephone calls using a cel-
lular phone in vehicle compartment.

5 or less cellular phones can be registered into the TEL adapter unit.

Hands-free phone mode starts by transmitting steering switch signal to TEL adapter unit when pressing
button.

Hands-free phone mode ends by transmitting steering switch signal to TEL adapter unit when pressing
button.

When uttering to the TEL microphone, TEL microphone signal (audio signal) is transmitted from the TEL
microphone to the TEL adapter unit and transmitted to the cellular phone with the Bluetooth
® communi-
cation.

Audio signals from a party at the other end are transmitted from the cellular phone to the TEL adapter unit
with the Bluetooth
® communication, and transmitted from the TEL adapter unit to the audio unit, then the
party's voice is output from the front door speaker.

Audio unit switches the voice from front speaker RH to TEL voice when receiving TEL ON signal from TEL
adapter unit.
