NAVIGATION SYSTEM
Revision: November 20092006 QX56

Position detection is not possible when the vehicle is in an area where radio waves from the GPS satellite
do not reach, such as in a tunnel, parking lot in a building, and under an elevated highway. Radio waves
from the GPS satellites may not be received when some object is located over the GPS antenna.

Position correction by GPS is not available while the vehicle is stopped.
COMPONENT DESCRIPTION
NAVI Control Unit

The gyro (angular speed sensor) and the DVD-ROM drive are
built-in units that control the navigation functions.

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 DVD-ROM map.
Location information is shown on liquid crystal display (display
unit).

Maps, traffic control regulations, and other pertinent information
can be easily read from the DVD-ROM disc.

The oscillator gyro sensor is used to detect changes in vehicle
steering angle.
Map DVD-ROM

The map DVD-ROM has maps, traffic control regulations, and other pertinent information.

To improve DVD-ROM map matching and route determination functions, the DVD-ROM uses an exclusive
Nissan format. Therefore, the use of a DVD-ROM provided by other manufacturers cannot be used.
Display Control Unit
The display control unit coordinates audio and video signals between the NAVI control unit and the display
unit.
Display Unit
Displays NAVI system information.
AV Switch
AV switch allows user to input NAVI display settings. Self diagnostics are initiated using AV switch.
GPS Antenna
GPS antenna sends signals to NAVI control unit.
CAN Communication System DescriptionEKS00BJE
Refer to LAN-26, "CAN COMMUNICATION" .
