crystal displays.This is not a malfunction.
Some menu items cannot be
selected.Some menu items become unavailable while the
vehicle is driven.Park the vehicle in a safe location, and
then operate the navigation system.
Symptom Possible cause Possible solution
Names of roads and locations dif-
fer between Plan view and Bird-
view™.This is because the quantity of the displayed infor-
mation is reduced so that the screen does not
become too crowded. There is also a chance that
names of the roads or locations may be displayed
multiple times, and the names appearing on the a
screen may be different because of a processing
procedure.This is not a malfunction.
The vehicle icon is not displayed in
the correct position.The vehicle was transported after the ignition switch
was turned off, for example, by a ferry or car trans-
porter.Drive the vehicle for a while on a road
whereGPScanbereceived.
The position and direction of the vehicle may be
incorrect depending on the driving environments and
the levels of positioning accuracy of the navigation
system.This is not a malfunction. Drive the vehi-
cle for a while to automatically correct the
position and direction of the vehicle icon.
Whenthevehicleistravellingona
new road, the vehicle icon is
located on another road nearby.Because the new road is not stored in the map data,
the system automatically places the vehicle ion on
the nearest road available.Updated road information will be included
in the next version of the map DVD-ROM.
The screen does not switch to the
night screen even after turning on
the headlights.The daytime screen was set the last time the head-

EXAMPLES OF CURRENT LOCATION MARK DISPLACEMENT
It calculates vehicle travel by reading travel distance and turn angle. Therefore, if the vehicle is driven in the
following manner, a mistake will occur in the current location display. If correct location has not been restored
after driving the vehicle normally, perform location correction.

Cause (condition) Driving condition Remarks (correction, etc.)
Road pat-
ternY-intersections
At a Y intersection or similar gradual
division of roads, errors in the direc-
tion of travel deduced by the sensor
may result in the current location
mark appearing on the wrong road.
If after traveling about 10 km (6
MPH) the correct location has not
been restored, perform location
correction and, if necessary, direc-
tion correction. Spiral roads
When driving on a large, continuous
spiral road (such as loop bridge),
turning angle errors accumulate and
vehicle mark may deviate from the
correct location.
Straight roads
When driving on a long, straight,
slowly curving road without stop-
ping, 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 vehi-
cle turns at a corner.
Switchback turns
Whendrivingonazigzagroad,the
map may be matched to other roads
in a similar direction nearby at every
turn, and the vehicle mark may
deviate from the correct location.
Grid pattern roads
When driving in a location where
roads are laid out in a grid pattern,
where many roads are running in
the similar direction nearby, the map
may be matched to them by mistake
and the vehicle mark may deviate
from the correct location.
Parallel roads
When two roads are running in par-
allel (such as highway and side-
way), the map may be matched to
the other road by mistake and the
vehicle mark may deviate from the
correct location.

PlaceIn a parking lotWhen driving in a parking lot, or
other location 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 deviated from the correct loca-
tion.
When driving in circle or turning the
steering wheel repeatedly, direction
errors accumulate, and the vehicle
mark may deviate from the correct
location.
If after traveling about 10 km (6
MPH) the correct location has not
been restored, perform location
correction and, if necessary, direc-
tion correction. TurntableWhentheignitionswitchisOFF,the
navigation system cannot receive
the signal from the gyroscope
(angular speed sensor). Therefore,
the displayed direction may be
incorrect and the correct road may
not be easily returned to after rotat-
ing the vehicle on a turntable with
the ignition OFF.
Slippery roadsOn 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.
SlopesWhen parking in sloped garages,
when traveling 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 dataRoads not displayed on the map
screenWhen 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 devi-
ate 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 vehi-
cle mark may deviate from the cor-
rect road. Cause (condition) Driving condition Remarks (correction, etc.)

THE CURRENT POSITION MARK SHOWS A POSITION THAT IS COMPLETELY INCORRECT.
In the following cases, the current location mark may be displayed in a location that is completely incorrect. If
so, perform position/direction correction.
lWhen location correction has not been done
–If GPS satellite reception is poor and the current location mark slips out of place, it may shift to a com-
pletely unexpected location and not return unless location correction is performed. The position will be
corrected if a GPS signal can be received.
lWhen vehicle has traveled by ferry, or when vehicle has been towed.
VehicleUse of tire chains.
The vehicle mark may deviate from
the correct road.Drivethevehicleforawhile.Ifdis-
tance still deviates, adjust it with
the distance adjustment function. (If
tire chains are removed, recover
the original value.)
Use of tires other than the specified
sizeReplace all tires with the specified
size tire.
Malfunctioning air pressure of tireAdjust all tires to the specified air
pressure.
Replace tireDrive the vehicle for a while. If the
distance is still not in the correct
location, it adjusts with the distance
adjustment function.
Driving
mannerJust after the engine is startedIf vehicle is driven off just after the
engine is started when gyroscope
(angular speed sensor) correction is
not completed, the vehicle can can
be shown in the incorrect direction
and may deviate from the correct
location.Wait for a short while before driving
after starting the engine.
Continuous driving without stoppingWhen driving long distances without
stopping, direction errors may accu-
mulate, and the current location
mark may deviate from the correct
road.Stop and adjust orientation.
Abusive drivingSpinning 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 traveling about 10 km (6
MPH) the correct location has not
been restored, perform location
correction and, if necessary, direc-
tion correction.
Position cor-
rection
methodPosition correction accuracy
If accuracy of location settings is
poor, accuracy may be reduced
when correct road cannot be found,
particularly in places where there
are many roads.From the roads displayed on the
screen, input a position within an
accuracy of 1mm (0.04 in).
CAUTION:
When correcting, use the most
detailed map possible.
Direction when location is corrected
If accuracy of location settings dur-
ing correction is poor, accuracy may
be reduced afterwards.Perform direction correction. Cause (condition) Driving condition Remarks (correction, etc.)

TROUBLE DIAGNOSIS
–Because calculation of the current location cannot be done when traveling with the ignition OFF, for exam-
ple when traveling by ferry or when being towed, the location before travel is displayed. If the precise loca-
tioncanbedetectedwithGPS,thelocationwillbecorrected.
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.
lWhen map matching has been done
–If 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 incorrect road or to a
location which is not on a road.
lWhen GPS location correction has been done
–If current location and the current location mark are different when location is corrected using GPS mea-
surements, 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.
THE CURRENT LOCATION MARK IS IN A RIVER OR THE 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.
CURRENT LOCATION MARK ROTATES WITHOUT OPERATION
If the ignition switch is turned ON with the turntable rotating, the rotating condition is recorded as the stop con-
dition. Therefore, the current location mark might rotate when actually stopping.
WHEN DRIVING ON THE SAME ROAD, SOMETIMES THE CURRENT LOCATION MARK IS IN
THE CORRECT PLACE AND SOMETIMES IT IS IN THE INCORRECT PLACE.
The conditions of the GPS antenna (GPS data) and gyroscope (angular speed sensor) change gradually.
Depending on the road traveled and operation of the steering wheel, the location detection results will be dif-
ferent. Therefore, even on a road on which the location has never been incorrect, conditions may cause the
vehicle mark to deviate.
LOCATION CORRECTION BY MAP MATCHING IS SLOW.
lThe 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.
lBecause of the way map matching operates, when there are many roads running in similar directions in
the surrounding area a matching determination may be impossible. The location will remain uncorrected
until some special feature is found.
ALTHOUGH THE GPS RECEIVING DISPLAY IS GREEN, THE VEHICLE MARK DOES NOT
RETURN TO THE CORRECT LOCATION.
lGPS accuracy has a malfunction range of about 10 m. In some cases the current location mark may not
be on the correct street, even when GPS location correction is done.
lThe navigation system compares the results of GPS location detection with the results from map-match-
ing location detection. The one that is determined to have higher accuracy is used.
lPosition correction by GPS is not available while the vehicle is stopped.
THE NAME OF THE CURRENT PLACE IS NOT DISPLAYED.
The current place name might not be displayed when there is no name of place information in the map screen.
THE DISPLAY IS DIFFERENT BETWEEN BIRDVIEW®AND (FLAT) MAP DISPLAY.
The following is different at birdview®.
lThe current place name displays names that are primarily in the direction of vehicle travel.
lThe amount of time before the vehicle travel or turn angle is updated on the screen is longer than for the
(flat) map display.
lThe conditions for display of place names, roads, and other data are different for nearby areas and for
more distant areas.
lSome trimming of the character data is done to prevent the display from becoming too complex. In some
cases and in some locations, the display contents may differ.
lThe same place name, street name, etc. may be displayed multiple times.
