DETAILED MAP COVERAGE AREAS
(MCA) FOR THE NAVIGATION SYS-
TEM
This system is designed to help you reach your
destination, and it also performs other functions
as outlined in this manual. However, you, the
driver, must use the system safely and properly.
Information concerning road conditions, traffic
signs and the availability of services may not
always be up-to-date. The system is not a
substitute for safe, proper and legal driving.
Map data covers select metropolitan areas in the
United States.
Map data is available on map DVD-ROMs. For
information about map DVD-ROMs, contact a
NISSAN dealer or call the NISSAN NAVIGA-
TION SYSTEM HELPDESK. See the contact
information on the inside front cover of this
manual.
Map data includes two types of areas: “Detailed
coverage areas” providing all detailed road data
and other areas showing “Main roads only”.
NOTE:
Detailed map data is not available in many
areas and is generally limited to select
major metropolitan areas.
For information on which metropolitan areas are
in detailed coverage areas, please refer to the
NISSAN Navigation System Software Booklet
(included) . When you purchase an updated map
DVD-ROM, a new software booklet will be
included.

.The displayed street names may sometimes
differ from the actual names, or “UN-
KNOWN STREET NAME” may be dis-
played.
.Voice guidance is not available when the
[Guidance Voice] indicator is not illuminated.
.Voice guidance will start when the vehicle
enters the suggested route. Refer to the
map for directions to the starting point of the
route.
.When approaching a waypoint, voice gui-
dance will announce, “You have arrived at
waypoint 1 (2, 3, 4,...) .” Voice guidance will
switch to the next section of the route. When
voice guidance is not available, refer to the
map for directions.
.In some cases, voice guidance ends before
arrival at the destination. Refer to the
destination icon on the map to reach the
destination.
.If the system recognizes on which side the
destination (waypoint) is located, voice
guidance will announce “on the right/left”
after announcing the arrival at the destina-
tion.
.Voice guidance may be partially operational
or inoperative due to the angle of roads at an
intersection.HOW TO ORDER MAP DVD-ROM

ZENRIN CO., LTD. has added, processed
and digitized data based on the digital road
map data of Navigation Technologies Cor-
poration. Due to the production timing of the
map data, some new roads may not be
included in this map data or some of the
names or roads may be different from those
at the time you use this map DVD-ROM.
2. Traffic control and regulation data used in
this map DVD-ROM may be different from
those at the time you use this map DVD-
ROM due to the data production timing.
When driving your vehicle, follow the actual
traffic control signs and notices on the
roads.

General system information9-15

Symptom Possible cause Possible solution
Names of roads and locations differ
between Plan view and Birdview
TM.This is because the quantity of the displayed information 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 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 pushed 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 icon 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 vehicle for a while
to automatically correct the position and direction of
the vehicle icon.
“CURRENT VEHICLE LOCATION”
(page 9-3)
When the vehicle is traveling on a 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 icon 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 head-
lights.The daytime screen was set the last time the headlights were turned on. Set the screen to the night screen mode using
<>(Day/Night) when you turn on the head-
lights.
“DISPLAY SETTINGS” (page 8-3)

vehicle is moving.The current location map screen is not displayed. Push
<MAP>.
The vehicle icon is not displayed. The current location map screen is not displayed. Push

The GPS indicator on the screen re-
mains gray.GPS signals cannot be received under certain conditions, such as in a
