Revision: 2006 December 2006 FX35/FX45
Trouble DiagnosisNKS003LC
The majority of the audio malfunctions are the result of outside causes (bad CD, electromagnetic interfer-
ence, etc.). Check the symptoms below to diagnose the malfunction.
The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunction-
ing. Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and
operation of each piece of electrical equipment, and then determine the cause.
Make sure that other operation except audio system can be performed with A/C and AV switch. If these
operations are inoperative with A/C and AV switch, refer to AV- 8 4 , "
Unable to Operate System with A/C
and AV Switch" (Without navigation system), or AV- 1 3 9 , "Unable to Operate System with A/C and AV
Switch" (With navigation system).
Refer to "SERVICE BULLETIN ITB04-055" for the diagnosis of satellite radio.
NOTE:
Noise resulting from variations in field strength, such as fading noise and multi-path noise, or external noise
from trains and other sources. It is not a malfunction.
Fading noise: This noise occurs because of variations in the field strength in a narrow range due to moun-
tains or buildings blocking the signal.
Multi-path noise: This noise results from a time difference between the broadcast waves directly from the
station arriving at the antenna and the waves reflected by mountains or buildings.

NAVIGATION SYSTEM
Revision: 2006 December 2006 FX35/FX45
GPS (Global Positioning System)
GPS (Global Positioning System) was developed for and is con-
trolled by the US Department of Defense. The system utilizes GPS
satellites (NAVSTAR), sending out radio waves while flying on an
orbit around the earth at an altitude of approximately 21,000 km
(13,100 miles).
The GPS receiver calculates the vehicle's position in three dimen-
sions (latitude/longitude/altitude) according to the time lag of the
radio waves received from four or more GPS satellites (three-dimen-
sional positioning). If radio waves were received only from three
GPS satellites, the GPS receiver calculates the vehicle's position in
two dimensions (latitude/longitude), and utilize the altitude data cal-
culated previously with radio waves from four or more GPS satellites
(two-dimensional positioning).
Position correction by GPS is not available while the vehicle is stopped.
Accuracy of GPS will deteriorate under the following conditions:
In two-dimensional positioning, GPS accuracy will deteriorate when altitude of the vehicle position
changes.
The accuracy can be even lower depending on the arrangement of the GPS satellites utilized for the posi-
tioning.
Position detection is not possible when 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.
NOTE:
Even a high-precision three dimensional positioning, the detection result has an error about 10 m (30ft).
Because the signals of GPS satellite is controlled by the Tracking and Control Center in the United States,
the accuracy may be degraded lower intentionally or the radio waves may stop.

Component DescriptionNKS003K1
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.
Locational information is shown on liquid crystal display panel.
DVD-ROM Drive
Maps, traffic control regulations, and other pertinent information can
be easily read from the DVD-ROM.
DVD-ROM
The 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.
Gyro (Angular Speed Sensor)
The oscillator gyro sensor is used to detect changes in vehicle steering angle.
The gyro is built into the navigation (NAVI) control unit.
GPS ANTENNA
The GPS antenna receives and amplifies the radio waves from the GPS satellites, and then transmits the GPS
signal to NAVI control unit.
DISPLAY CONTROL UNIT
Display control unit draws a status of the audio and air condi-
tioner, a TRIP screen, a FUEL ECONOMY screen, etc., and
transmits the image signals to the display screen.
It receives operation signals of audio and air conditioner from A/
C and AV switch, and transmits the operation signal of audio to
the audio unit via the communication line and transmits the
operation signal of air conditioner to the meter and A/C amp. via
CAN communication.

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.
