PlaceIn a parking lot When driving in a parking lot, or other loca-
tion where there are no roads on the map,
matching may place the vehicle mark on a
nearby road. When the vehicle returns to
the road, the vehicle mark may have devi-
ated from the correct location.
When driving in circle or turning the steer-
ing wheel repeatedly, direction errors accu-
mulate, and the vehicle mark may deviate
from the correct location.
If after travelling about 10km
(6miles) the correct location
has not been restored, perform
location correction and, if nec-
essary, direction correction. Turn ta ble
When the ignition switch is OFF, the navi-
gation system cannot get the signal from
the gyroscope (angular speed sensor).
Therefore, the displayed direction may be
wrong and the correct road may not be
easily returned to after rotating the vehicle
on a turn table with the ignition OFF.
Slippery roads On snow, wet roads, gravel, or other roads
where tires may slip easily, accumulated
mileage errors may cause the vehicle mark
to deviate from the correct road.
Slopes When parking in sloped garages, when
travelling on banked roads, or in other
cases where the vehicle turns when tilted,
an error in the turning angle will occur, and
the vehicle mark may deviate from the
road.
Map dataRoad not displayed on the map screen
When driving on new roads or other roads
not displayed on the map screen, map
matching does not function correctly and
matches the location to a nearby road.
When the vehicle returns to a road which is
on the map, the vehicle mark may deviate
from the correct road.
Different road pattern
(Changed due to repair)
If the road pattern stored in the map data
and the actual road pattern are different,
map matching does not function correctly
and matches the location to a nearby road.
The vehicle mark may deviate from the
correct road.
Vehicle Use of tire chainsWhen tire chains are used, the mileage is
not correctly detected, and the vehicle
mark may deviate from the correct road.Drive the vehicle for a while. If
the distance is still deviated,
adjust it by using the distance
adjustment function. (If the tire
chain is removed, recover the
original value.) Cause (condition) –: While driving ooo: Display Driving condition Remarks (correction, etc.)

CURRENT LOCATION 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.
CURRENT-LOCATION 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 gyroscope
(angular speed sensor) correction is not
completed, the vehicle can lose its direc-
tion and may have deviated from the cor-
rect location.Wait for a short while before
driving after starting the engine.
Continuous driving without stopping When driving long distances without stop-
ping, direction errors may accumulate, 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 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 nec-
essary, direction correction.
How to cor-
rect 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. 1mm.
Caution: Whenever possible,
use detailed map for the cor-
rection.
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) –: While driving ooo: Display Driving condition Remarks (correction, etc.)

NAVIGATION SYSTEM
Revision: 2004 November 2004 FX35/FX45
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 to 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.
