Cause (condition)

Driving condition

Remarks (correction, etc.)

Road
pattern

Y–intersections

At a Y intersection or similar gradual divi-
sion of roads, mistakes in the direction of 
travel deduced by the sensor may result in 
the vehicle mark appearing on the wrong 
road.

If after traveling about 10 km (6 
miles) the correct location has 
not been restored, perform lo-
cation correction, and if neces-
sary, direction correction.

Spiral roads

When driving on a large, continuous spiral 
road (such as loop bridge), turning angle 
error is accumulated and the vehicle mark 
may deviate from the correct location.

Straight roads

When driving on a long, straight road and  
gentle curve road without stopping, map-
matching does not work effectively enough 
and distance errors may accumulate. As a 
result, the vehicle mark may deviate from 
the correct location when the vehicle turned 
at a corner.

Switchback turn

When driving on a zigzag road, the map 
may be matched to other roads in the simi-
lar direction nearby at every turn, and the 
vehicle mark may deviate from the correct 
location.

Roads laid out in a grid pattern

When driving at where roads are laid out in 
a grid pattern, where many roads are run-
ning in the similar direction nearby, the map 
may be matched to them by mistake and 
the vehicle mark may deviate from the cor-
rect location.

Parallel roads

When two roads are running in parallel 
(such as highway and sideway), the map 
may be matched to the other road by mis-
take and the vehicle mark may deviate from 
the correct location.

Place

In 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 traveling about 10 km (6 
miles) the correct location has 
not been restored, perform lo-
cation correction and, if neces-
sary, direction correction.

Turntable

When the ignition switch is off, the naviga-
tion system cannot get the signal from the 
gyroscope (angular speed sensor). There-
fore, the displayed direction may be wrong 
and the correct road may not be easily re-
turned 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 
traveling on banked roads, or in other cas-
es where the vehicle turns when tilted, an 
error in the turning angle will occur, and the 
vehicle mark may deviate from the road.

Map data

Road 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 cor-
rect road.

Vehicle

Use of tire chains

When 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, ad-
just it by using the distance ad-
justment function. (If the tire 
chain is removed, recover the 
original value.)

NORMAL OPERATING CONDITION

VEHICLE MARK SHOWS A POSITION WHICH IS COMPLETELY WRONG

In the following cases, the vehicle 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 direction correction.
• When location correction has not been done
- If the receiving conditions of the GPS satellite signal is poor, if the vehicle 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 traveling 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.

VEHICLE MARK JUMPS

In the following cases, the vehicle 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 vehicle mark are different when map matching is done, the vehicle 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 vehicle mark are different when the location is corrected using GPS measure-

ments, the vehicle mark may seem to jump. At this time, the location may be “corrected” to a location which
is not on a road.

VEHICLE MARK IS IN A RIVER OR SEA

The navigation system moves the vehicle mark with no distinction between land and rivers or sea. If the vehi-
cle mark is somehow out of place, it may appear that the vehicle is driving in a river or the sea.

VEHICLE MARK AUTOMATICALLY ROTATES

Precautions 
for driving

Just after the engine is started

If the vehicle is driven off just after the en-
gine is started when the gyroscope (angu-
lar speed sensor) correction is not 
completed, the vehicle can lose its direction 
and may have deviated from the correct lo-
cation.

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 vehicle mark may deviate from the cor-
rect 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 detec-
tion, and may cause the vehicle mark to de-
viate from the correct road.

If after traveling about 10 km (6 
miles) the correct location has 
not been restored, perform lo-
cation correction and, if neces-
sary, direction correction.

How to 
correct
location

Position 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 (0.04 in).
Caution: Whenever possible, 
use detailed map for the correc-
tion.

Direction when location is corrected

If the accuracy of location settings during 
correction is poor, accuracy may be re-
duced afterwards.

Perform direction correction.

The system wrongly memorizes the rotating status as stopping when the ignition switch is turned ON with the
turntable rotating. That causes the vehicle mark to rotate when the vehicle is stopped.

WHEN DRIVING ON SAME ROAD, SOMETIMES VEHICLE 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 directions

in the surrounding area, no matching determination may be made. The location may not be corrected until
some special feature is found.

NAME OF ROAD IS NOT DISPLAYED

The current road name may not be displayed if there are no road 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.
