NAVIGATION SYSTEM
Revision: October 20052005 QX56

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, the alternative
routes will be shown in different order of priority, and the wrong
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 the road on
which the vehicle is driving is new and not recorded in the map
DVD-ROM, or when the 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 leap 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 map DVD-ROM is limited. Therefore, when
there is an excessive gap between the current vehicle position
and the position on the map, correction by map-matching is not possible.
GPS (GLOBAL POSITIONING SYSTEM)
GPS (Global Positioning System) has been developed and con-
trolled by the US Department of Defense. The system utilizes GPS
satellite (NAVSTAR), sending out radio waves while flying on an orbit
around the earth at the height of approx. 21,000 km (13,000 miles).
The GPS receiver calculates the vehicle's position in three dimen-
sions (latitude/longitude/altitude) according to the time lag of the
radio waves received from four or more GPS satellites (three-dimen-
sional positioning). If radio waves were received only from three
GPS satellites, the GPS receiver calculates the vehicle's position in
two dimensions (latitude/longitude), utilizing the altitude data calcu-
lated previously by using radio waves from four or more GPS satel-
lites (two-dimensional positioning).
Accuracy of the GPS will deteriorate under the following conditions.

In two-dimensional positioning, the GPS accuracy will deteriorate when the altitude of the vehicle position
changes.

There may be an error of approximately 10 m (30 ft) in position detected by three-dimensional positioning,
which is more accurate than two-dimensional positioning. The accuracy can be even lower depending on
the arrangement of the GPS satellites utilized for the positioning.

Position detection is not possible when the vehicle is in an area where radio waves from the GPS satellite
do not reach, such as in a tunnel, parking lot in a building, and under an elevated highway. Radio waves
from the GPS satellites may not be received when some object is located over the GPS antenna.

Position correction by GPS is not available while the vehicle is stopped.

COMPONENT DESCRIPTION
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.
Location information is shown on liquid crystal display (display
unit).
DVD-ROM Drive
Maps, traffic control regulations, and other pertinent information can
be easily read from the DVD-ROM disc.
Map DVD-ROM

The map 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.
BIRDVIEW™
The BIRDVIEW™ provides a detailed and easily seen display of road conditions covering the vehicle's imme-
diate to distant area.

CURRENT LOCATION MARK IS IN A RIVER OR SEA
The navigation system moves the current-location mark with no distinction between land and rivers or sea. If
the location mark is somehow out of place, it may appear that the vehicle is driving in a river or the sea.
WHEN DRIVING ON SAME ROAD, SOMETIMES CURRENT-LOCATION MARK IS IN RIGHT
PLACE AND SOMETIMES IT IS WRONG PLACE
The conditions of the GPS antenna (GPS data) and gyroscope (angular speed sensor) change gradually.
Depending on the road traveled and the operation of the steering wheel, the location detection results will be
different. Therefore, even on a road on which the location has never been wrong, conditions may cause the
vehicle mark to deviate.
LOCATION CORRECTION BY MAP-MATCHING IS SLOW

The map-matching function needs to refer to the data of the surrounding area. It is necessary to drive
some distance for the function to work.

Because map-matching operates on this principle, when there are many roads running in similar direc-
tions in the surrounding area, no matching determination may be made. The location may not be cor-
rected until some special feature is found.
ALTHOUGH GPS RECEIVING DISPLAY IS GREEN, VEHICLE MARK DOES NOT RETURN TO
CORRECT LOCATION

The GPS accuracy has an error of approximately 10 m (30 ft). In some cases the current-location mark
may not be on the correct street, even when GPS location-correction is done.

The navigation system compares the results of GPS location detection with the results from map-match-
ing location detection. The one which is determined to have higher accuracy is used.

GPS location correction may not be performed when the vehicle is stopped.
NAME OF CURRENT PLACE IS NOT DISPLAYED
The current place name may not be displayed if there are no place names displayed on the map screen.
CONTENTS OF DISPLAY DIFFER FOR BIRDVIEW™ AND THE (FLAT) MAP SCREEN
Difference of the BIRDVIEW™ screen from the flat map screen are as follows.

The current place name displays names which are primarily in the direction of vehicle travel.

The amount of time before the vehicle travel or turn angle is updated on the screen is longer than for the
(flat) map display.

The conditions for display of place names, roads, and other data are different for nearby areas and for
more distant areas.

Some thinning of the character data is done to prevent the display becoming too complex. In some cases
and in some locations, the display contents may differ.

The same place name, street name, etc. may be displayed multiple times.
