BASIC OPERATIONS
NOTE:
Locations stored in the Address Book and other memory functions may be lost if the vehicle's battery is disconnected or is disc harged. If
this occurs, service the vehicle's battery as necessary and re-enter the information in the Address Book.
VEHICLE MARKS
Symptom Possible cause Possible solution
No image is displayed. The brightness is at the lowest setting. Adjust the brightness of the display.
The display is turned off. Press and hold the button to turn on the
display.
No voice guidance is available.
The volume is too high or too low. The volume is not set correctly, or it is turned
off. Adjust the volume of voice guidance.
No map is displayed on the
screen. The DVD-ROM is not inserted, or it is inserted
upside down. Insert the DVD-ROM correctly.
A screen other than map screen is displayed. Press the “MAP” button.
The pickup lens of the DVD unit is dirty. The pickup lens can become dirty depending
on the usage of the vehicle. Contact a NISSAN
dealer or qualified workshop for pickup lens
cleaning.
The screen is too dim.
The movement is slow. The temperature in the interior of the vehicle is
low. Wait until the interior of the vehicle has
warmed up.
Some pixels in the display are
darker or brighter than others. This condition is an inherent characteristic of
liquid 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, then oper-
ate 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
information is reduced so that the screen does
not become difficult to read. There is also a
chance that names of the roads or locations
may be displayed several times, and the names
appearing on the screen may be different
because of a processing procedure. This is not a malfunction.
The vehicle mark 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 transporter. Drive the vehicle for a while on a road where
GPS signals can be received.
The position and direction of the vehicle mark
may be incorrect depending on the driving envi-
ronments and the levels of positioning accuracy
of the navigation system. This is not a malfunction. Drive the vehicle for
a while to automatically correct the position
and direction of the vehicle mark.
When the vehicle is travelling on a
new road, the vehicle mark is
located on another road nearby. The system automatically places the vehicle
mark on the nearest available road, because
the new road is not stored in the map data. Updated road information will be included in
the next version of the 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
headlights were turned on. Set the screen to the night screen mode using
button when turning on the headlights.
The map does not scroll even
when the vehicle is moving. The current location map screen is not dis-
played. Press the “MAP” button.
The vehicle mark is not displayed. The current location map screen is not dis-
played. Press the “MAP” button.

DVD-ROM
ROUTE CALCULATION AND VISUAL GUIDANCE
The GPS indicator on the screen
remains gray. GPS signals cannot be received depending on
the vehicle location, such as in a parking
garage, on a road that has numerous tall build-
ings, etc. Drive on an open, straight road for a while.
A sufficient amount of GPS satellites is not
available. Please wait for the satellites to move to loca-
tions available for the navigation system.
The location of the vehicle mark is
misaligned from the actual posi-
tion. 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 approximately
30 km/h (19 MPH) for about 30 minutes] to
automatically correct the vehicle's mark posi-
tion. If this does not correct the vehicle mark
position, contact a NISSAN dealer or qualified
workshop.
The map data has a mistake or is incomplete
(the vehicle mark position is always misaligned
in the same area). Updated road information will be included in
the next version of the DVD-ROM.
Symptom Possible cause Possible solution
Symptom Possible cause Possible solution
The message “Error” appears. The DVD-ROM is dirty or partially damaged. Check the DVD-ROM and wipe it clean with a
soft cloth.
If any damage, replace the DVD-ROM.
Symptom Possible cause Possible solution
In the auto re-route calculation,
waypoints are not included. Waypoints that you have already passed are
not included in the auto re-route calculation. To go to that waypoint again, it is necessary to
edit the route.
Route information is not dis-
played. Route calculation has not yet been performed.
Set the destination and perform route calcula-
tion.
Vehicle is not driving on the suggested route. Drive on the suggested route.
Route guidance is set to off. Turn on the route guidance.
The auto re-route calculation (or
detour calculation) suggests the
same route as the one previously
suggested. Route calculations took priority conditions into
consideration, but the same route was calcu-
lated. This is not a malfunction.
A waypoint cannot be added. Five waypoints are already set on the route,
including the ones that you have already
passed. A maximum of 5 waypoints can be set on the
route. If you want to go to 6 or more waypoints,
perform route calculations several times, as
necessary.
The suggested route is not dis-
played. Roads near the destination cannot be calcu-
lated. 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 your trip by selecting one or two inter-
mediate destinations, and perform a global
route calculation based on multiple route cal-
culations.
There are time restricted roads (day of week,
time) near the current vehicle location or desti-
nation. Set [Use Time Restricted Roads] to off.
The part of the route already
passed is deleted. A route is managed by sections between way-
points. If passing 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.

VOICE GUIDANCE
An indirect route is suggested. If there are restrictions (such as one-way
streets) on roads close to the starting point or
destination, the system may suggest an indirect
route. Adjust the location of the starting point or desti-
nation.
The system may suggest an indirect route
because route calculation does not take into
consideration some areas such as narrow
streets (grey roads). Reset the destination to a main or ordinary
road, and recalculate the route.
The landmark information does
not correspond to the actual infor-
mation. This may be caused by insufficient or incorrect
data on the DVD-ROM. Updated information will be included in the
next version of the DVD-ROM.
The suggested route does not
exactly connect with the starting
point, waypoints, or destination. There is no data for route calculation closer to
these locations. Set the starting point, waypoints and destina-
tion on a main road, and perform route calcula-
tion.
Symptom Possible cause Possible solution
Symptom Possible cause Possible solution
Voice guidance is not available. Voice guidance is only available at certain inter-
sections marked with . In some cases, voice
guidance is not available even when the vehicle
should make a turn. This is not malfunction.
The vehicle has deviated from the suggested
route. Go back to the suggested route or request
route calculation again.
Voice guidance is set to off. Turn on the voice guidance.
Route guidance is set to off. Turn on the route guidance.
The guidance content does not
correspond to the actual condition. The content of voice guidance may vary,
depending on the types of intersections where
turns are made. Follow all traffic rules and regulations.
