2001 INFINITI QX4 navigation system

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 DESCRIPTIONNBEL0228S02Display & NAVI Control UnitNBEL0228S0201IThe gyro (angular speed sensor) and the CD-ROM drive are
built-in units that control the navigation functions.
ISignals 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.
IFinger-operated touch switches are positioned on the liquid
crystal display panel for easy operation.
IThe 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.
SEL689V
CD-ROM DriverNBEL0228S0202Maps, traffic control regulations, and other pertinent information
can be easily red from the CD-ROM disc.
NOTE:
IWhen removing the CD-ROM, allow it to remain open until the
liquid crystal display locks.
IThe liquid crystal display must be closed when the vehicle is
running.
IDo not place cups, cans or other containers containing liquids
on top of the liquid crystal display.
Map CD-ROMNBEL0228S0203IThe map CD-ROM has maps, traffic control regulations, and
other pertinent information.
ITo 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.

SEL690V
Gyro (Angular Speed Sensor)NBEL0228S0204IThe oscillator gyro sensor is used to detect changes in vehicle
steering angle.
IThe oscillator gyro periodically senses oscillatory variation at
the oscillation terminals. This variation is caused by changes
in the vehicle angular velocity. Voltage variations are sensed
by ceramic voltage sensors at the left and right sides of the
terminals. Vehicle angular velocity corresponds directly with
these changes in voltage.
IThe gyro is built into the display & navigation (NAVI) control
unit.

DescriptionNBEL0228S0206IDisplay area: Trapezoidal representation showing approximate
distances (Wn, D, and Wd).
ITen horizontal grid lines indicate display width while six verti-
cal grid lines indicate display depth and direction.
IDrawing line area shows open space, depth, and immediate
front area. Each area is to a scale of approximately 5:6:25.
IWhen the ªZMþº button is pushed, the view point height is
increased. Pushing the ªZM+º button decreases the height.
Pushing the ªZMþº button or the ªZM+º button during operation
indicates the scale change and the view point height at the
left-hand side of the screen.

FUNCTION OF TOUCH SWITCH (SUMMARY)=NBEL0228S03Display with Pushed ªMAPº SwitchNBEL0228S0301
SEL580X
The function of each touch switch is as follows:
1) Azimuth indication
2) Position marker
The tip of the arrow shows the current position. The shaft of
the arrow indicates the direction in which the vehicle is travel-
ing.
3) GPS reception signal (indicates current reception conditions)
4) Distance display (shows the distance in a reduced scale)
5) Current location voice information
(this information is available when the route guide is being
activated and the designated route is being traveled.)
6) Switch display from map screen to BIRDVIEW
Tscreen
(change to map screen on display when the BIRDVIEWTis
being used.)
7) The following items can be set.
ISave Current Location
IEdit Address Book
IGuide Volume
ISystem Setting
8) The route guide operation can be canceled.
