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 are prepared and prioritized
in addition to the road judged currently driven. Due to the dis-
tance and/or direction error, the incorrect road may be prioritized
and current-location mark may be repositioned to the wrong
road.
When two roads are running in parallel, they are judged to 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 DescriptionNKS003K1
NAVI CONTROL UNIT

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 this data with the data contained in the DVD-ROM map.
Locational information is shown on liquid crystal display panel.
DVD-ROM Drive
Maps, traffic control regulations, and other pertinent information can
be easily read from the DVD-ROM.
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 navigation (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 CONTROL UNIT

Display control unit draws a status of the audio and air condi-
tioner, a TRIP screen, a FUEL ECONOMY screen, etc., and
transmits the image signals to the display screen.

It receives operation signals of audio and air conditioner from A/
C and AV switch, and transmits the operation signal of audio to
the audio unit via the communication line and transmits the
operation signal of air conditioner to the meter and A/C amp. via
CAN communication.

DISPLAY

Images on the display include RGB image such as map screen.

Display control unit controls images on the display.
A/C AND AV SWITCH

A/C and AV switch, an integrated combination of audio and air
conditioner switches, are adopted.

Operation signal of audio is transmitted to the audio unit through
display control unit with the communication line. Operation sig-
nal of air conditioner is transmitted to meter and A/C amp.
through display control unit with CAN communication.

Prior to performing trouble diagnosis, make sure there are no corresponding description in the “Example of
Symptoms Possible No Malfunction”. Refer to AV- 1 5 2 , "
Example of Symptoms Possible No Malfunction" .
On Board Self-Diagnosis FunctionNKS003KE
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.

Confirmation/Adjustment mode displays trouble diagnosis that require an operation and a judgment by a
human (auto-decision cannot be performed by the system), confirmation of preset value, and an error his-
tory.
DIAGNOSIS ITEM
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
antenna.
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 ATC-52, "
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.
Navigation Steering
Angle
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
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 cal-
ibration is needed because of the use of tire chains.
Error History Malfunctions that occurred in the past are displayed, along with the num-
ber of times each has occurred. Time and location when/where the errors
occurred are also displayed.
Delete Unit Connection Log Erase the connection history of unit and error history.
CAN DIAG SUPPOPT MONITOR The transmitting/receiving of CAN communication can be monitored.
