NAVIGATION SYSTEM
System DescriptionINFOID:0000000001328739
 For Navigation System operation information, refer to Navigation System Owner's Manual.
 Each control unit that comprises the system is connect ed with a communication circuit. It transmits/receives
data signals including request signals and respons e signals, and controls the system.
 The display control unit transmits/receives data signals to/from each control unit with CAN communication. It
performs an arithmetical operation on fuel information values by using data obtained from the control units,
and then displays the calculated values on the screen.
 The display control unit receives door switch signal s from the BCM with CAN communication, and displays a
warning on the screen when driving over the set speed with a door half-shut.
 The display control unit receives vehicle speed signal s that are transmitted from the unified meter and A/C
amp., performs an arithmetical operation on drive info rmation values, and then displays the calculated val-
ues on the screen.
 The images displayed on the monitor screen c ontain NAVI control unit-generated RGB images.
 The display control unit controls image switching and image quality adjustments by communications with the
display.

NAVIGATION SYSTEM
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 DVD-ROM,
which is stored in the DVD-ROM drive (map-matching), and indi-
cated on the screen as a current-loc ation mark. More accurate data
is judged and used by comparing vehicle position detecti on 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.
More accurate traveling direction is selected because pr iorities are set for the signals from these two devices
according to the situation.
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 th is case, the current-location mark on the display must be
corrected manually.

Type Advantage Disadvantage
Gyroscope (angular velocity sen-
sor) Can detect the vehicle's turning angle quite
accurately. Direction errors
may accumulate when vehicle is
driven for long distances without stopping.
GPS antenna (GPS information) Can detect the vehicle's travel direction
(North/South/East/West). Correct direction cannot be detected when vehicle
speed is low.

NAVIGATION SYSTEM
 The gyro (angular speed sensor) and the DVD-ROM drive arebuilt-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 combining 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 r egulations, and other pertinent information.
 To improve DVD-ROM map matching and route determi nation functions, the DVD-ROM uses an exclusive
Nissan format. Therefore, the use of a DVD-RO M 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 conditioner, 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 com-
munication.

 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 con- ditioner switches, are adopted.
 Operation signal of audio is transmitted to the audio unit through
display control unit with the communication line. Operation signal
of air conditioner is transmitted to meter and A/C amp. through dis-
play control unit with CAN communication.
