When the radio wave from GPS satellites cannot be received,
for example, when the vehicle is in a tunnel, in a parking lot
inside building, under an elevated superhighway or near strong
power lines, the location may not be detected. Turbulent/
electric weather conditions may also affect positioning perfor-
mance. If something is placed on the antenna, the radio wave
from GPS satellites may not be received.

COMPONENT DESCRIPTION
Display & NAVI control unit
I
The gyro (angular speed sensor) and the CD-ROM drive are
built-in units that control the navigation functions.
I
Signals are received from the gyro, the vehicle speed sensor,
and the GPS antenna. Vehicle location is determined by com-
bining this data with the data contained in the CD-ROM map.
Locational information is shown on liquid crystal display panel.
I
Finger-operated touch switches are positioned on the liquid
crystal display panel for easy operation.
I
The touch switches used to control the equipment are beneath
a glass sheet and two resistance membranes at the top of the
liquid crystal display panel. The switches are sensitive to resis-
tance value where touched with your finger to detect operat-
ing status.

CD-ROM driver
Maps, traffic control regulations, and other pertinent information
can be easily red from the CD-ROM disc.
Note:
I
When removing the CD-ROM, allow it to remain open until the
liquid crystal display locks.
I
The liquid crystal display must be closed when the vehicle is
running.
I
Do not place cups, cans or other containers containing liquids
on top of the liquid crystal display.
Map CD-ROM
I
The map CD-ROM has maps, traffic control regulations, and
other pertinent information.
I
To improve CD-ROM map matching and route determination
functions, the CD-ROM uses an exclusive Nissan format.
Therefore, the use of a CD-ROM provided by other manufac-
turers cannot be used.
