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 position-
ing, 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.

Self-Diagnosis FunctionEKS00F32
DESCRIPTION

Diagnosis function consists of the self-diagnosis mode performed automatically and the CONFIRMATION/
ADJUSTMENT mode operated manually.

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 LCD screen.

CONFIRMATION/ADJUSTMENT mode is used to perform trouble diagnosis that require operation and
judgment by an operator (trouble that cannot be automatically judged by the system), to check/change the
set value, and to display the History of Errors of the navigation system.
DIAGNOSIS ITEM
Mode Description
Self-diagnosis

NAVI Control unit diagnosis (DVD-ROM drive will not be diagnosed when no
map DVD-ROM is in it.).

Performs diagnosis of each unit and connections between control unit and
GPS antenna, as well as between control unit and each unit.
Confirmation /
AdjustmentDisplayColor tone and shading of the screen can be checked by the display of a color
bar and a gray scale.
Vehicle signalsAnalyzes the following vehicle signals: Vehicle speed signal, light signal, igni-
tion switch signal, and reverse signal.
NavigationDisplay Longitude
& LatitudeDisplay the map. Use the joystick to adjust position. Longitude and latitude will
be displayed.
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 immediately restores
system accuracy in cases such as when distance calibration is needed
because of the use of tire chains in inclement weather.
Angle AdjustmentCorrects difference between actual turning angle of a vehicle and turning
angle of the car mark on the display.
Initialize LocationThis mode is for initializing the current location. Use when the vehicle is trans-
ported a long distance on a trailer, etc.
History of ErrorsDiagnosis results previously stored in the memory (before turning ignition
switch ON) are displayed in this mode. Time and location when/where the
errors occurred are also displayed.

THE CURRENT POSITION MARK SHOWS A POSITION WHICH IS COMPLETELY WRONG.
In the following cases, the current-location mark may appear on completely different position in the map
depending on the GPS satellite signal receiving conditions. In this case, perform location correction and direc-
tion correction.

When location correction has not been done
–If the receiving conditions of the GPS satellite signal is poor, if the current-location mark becomes out of
place, it may move to a completely different location and not come back if location correction is not done.
The position will be corrected if the GPS signal can be received.

When the vehicle has traveled by ferry, or when the vehicle has been being towed
–Because calculation of the current location cannot be done when travelling with the ignition OFF, for
example when traveling by ferry or when being towed, the location before travel is displayed. If the precise
location can be detected with GPS, the location will be corrected.
THE CURRENT POSITION MARK JUMPS.
In the following cases, the current-location mark may appear to jump as a result of automatic correction of the
current location.

When map matching has been done
–If the current location and the current-location mark are different when map matching is done, the current-
location mark may seem to jump. At this time, the location may be ″corrected″ to the wrong road or to a
location which is not on a road.

When GPS location correction has been done
–If the current location and the current-location mark are different when the location is corrected using GPS
measurements, the current-location mark may seem to jump. At this time, the location may be ″corrected″
to a location which is not on a road.
Precautions for
drivingJust after the engine is startedIf the vehicle is driven off just after
the engine is started when the gyro-
scope (angular speed sensor) cor-
rection is not completed, the vehicle
can lose its direction and may have
deviated from the correct location.Wait for a short while before driv-
ing after starting the engine.
Continuous driving without stopping When driving long distances without
stopping, direction errors may accu-
mulate, and the current-location
mark may deviate from the correct
road.Stop and adjust the orientation.
Abusive driving Spinning the wheels or engaging in
other kinds of abusive driving may
result in the system being unable to
perform correct detection, and may
cause the vehicle mark to deviate
from the correct road.If after travelling about 10 km (6
miles) the correct location has not
been restored, perform location
correction and, if necessary,
direction correction.
How to correct
locationPosition correction accuracy
If the accuracy of location settings is
poor, accuracy may be reduced
when the correct road cannot be
found, particularly in places where
there are many roads.Enter in the road displayed on the
screen with an accuracy of
approx. 1 mm.
NOTE:
Whenever possible, use detailed
map for the correction.
Direction when location is corrected
If the accuracy of location settings
during correction is poor, accuracy
may be reduced afterwards.Perform direction correction. Cause (condition) Driving condition Remarks (correction, etc.)
