MAP DVD-ROM
ROUTE CALCULATION AND VISUAL GUIDANCE
The location of vehicle icon is mis-
aligned from the actual position.When using tire chains or replacing the tires, speed
calculations based on the speed sensor may be
incorrect.Drive the vehicle for a while [at approxi-
mately 30km/h (19 MPH) for about 30
minutes] to automatically correct the vehi-
cle icon position.
If this does not correct the vehicle icon
position, contact an INFINITI dealer.
The map data has mistake or is incomplete (the
vehicle icon position is always misaligned in the
same area).Updated road information will be included
in the next version of the map DVD-ROM. Symptom Possible cause Possible solution
Symptom Possible cause Possible solution
The message “Error” appears. Map DVD-ROM is dirty or partially damaged.Check the DVD-ROM and wipe it clean
with a soft cloth.
If there is any damage, replace the DVD-
ROM.
Symptom Possible cause Possible solution
In the auto reroute calculation,
waypoints are not included.Waypoints already passed are not included in the
auto reroute calculation.In case of going to that waypoints again,
edit the route.
Route information is not displayed.Route calculation has not yet been performed.Set the destination and perform route cal-
culation.
The vehicle is not driven on the suggested route. Drive on the suggested route.
Route guidance is set to off. Turn on route guidance.
Route information is not provided for narrow streets
(roads displayed in gray).This is not a malfunction.
The auto reroute calculation (or
detour calculation) suggests the
same route as the one previously
suggested. Route calculation took priority conditions into con-
sideration, but the same route was calculated. This is not a malfunction.
A waypoint cannot be added.Five waypoints are already set on the route, includ-
ing ones that already passed.A maximum of 5 waypoints can be set on
the route. In case of going to 6 or more
waypoints, perform route calculations mul-
tiple times as necessary.
The suggested route is not dis-
played.Roads near the destination cannot be calculated.Reset the destination to a main or ordinary
road, and recalculate the route.
The starting point and destination are too close. Set a more distant destination.
The starting point and destination are too far away.Divide the way by selecting one or two
intermediate destinations, and perform
route calculations multiple times.
There are time restricted roads (by day of week, by
time) near the current vehicle location or destina-
tion.Set “Use Time Restricted Roads” to off.
A part of the route is not displayed.The suggested route includes narrow streets (roads
displayed in gray).This is not a malfunction.
The part of the route already
passed is deleted.A route is managed by sections between way-
points. If you passed the first waypoint, the section
between the starting point and the waypoint is
deleted. (It may not be deleted depending on the
area.)This is not a malfunction.

EXAMPLES OF VEHICLE MARK DISPLACEMENT
Vehicle's travel amount is calculated by reading its travel distance and turning angle. Therefore, if the vehicle
is driven in the following manner, an error will occur in the vehicle's current location display. If correct location
has not been restored after driving the vehicle for a while, perform location correction.

Cause (condition) Driving condition Remarks (correction, etc.)
Road
patternY–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
location correction, and if nec-
essary, 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
correct 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.

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 traveling about 10 km (6
miles) the correct location has
not been restored, perform
location correction and, if nec-
essary, 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
returned to after rotating the vehicle on a
turntable 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
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.
VehicleUse 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,
adjust it by using the distance
adjustment function. (If the tire
chain is removed, recover the
original value.) Cause (condition) Driving condition Remarks (correction, etc.)

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 exam-
ple when traveling by ferry or when being towed, the location before travel is displayed. If the precise loca-
tion 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 mea-
surements, the vehicle 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 started If 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 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
detection, and may cause the vehicle mark
to deviate from the correct road.If after traveling about 10 km (6
miles) the correct location has
not been restored, perform
location correction and, if nec-
essary, 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 (0.04 in).
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) Driving condition Remarks (correction, etc.)

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
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 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 vehicle 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.
