AUDIO SYSTEM

The majority of the audio troubles are the result of outside causes (bad CD, electromagnetic interference,
etc.).

Noise

The following noise results 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 the waves sent directly from the broadcast station arriving at the

antenna at a different time from the waves which reflect off mountains or buildings.

The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning.
Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and opera-
tion of each piece of electrical equipment, and determine the cause.
NOTE:
The source of the noise can be found easily by listening to the noise while removing the fuses of electrical
components, one by one.

Type of Noise and Possible Cause

NAVIGATION SYSTEM

Basic Operation

Vehicle Mark

Occurrence condition

Possible cause

Occurs only when engine is ON.

A continuous growling noise occurs. The speed of
the noise varies with changes in the engine speed.

• Ignition components

The occurrence of the noise is linked with the operation of the fuel pump.

• Fuel pump condenser

Noise only occurs when various
electrical components are oper-
ating.

A cracking or snapping sound occurs with the op-
eration of various switches.

• Relay malfunction, audio unit malfunction

The noise occurs when various motors are operat-
ing.

• Motor case ground
• Motor

The noise occurs constantly, not just under certain conditions.

• Rear defogger coil malfunction
• Open circuit in printed heater
• Poor ground of antenna feeder line

A cracking or snapping sound occurs while the vehicle is being driven, especially when
it is vibrating excessively.

• Ground wire of body parts
• Ground due to improper part installation
• Wiring connections or a short circuit

Name of the place vary with the
screen.

Some thinning of the character data is done to pre-
vent the display becoming to complex. In some
cases and in some locations, the display contents
may differ.
The same place name, street name, etc. may not
be displayed every time on account of the data
processing.

System is not malfunctioning.

Vehicle mark is not positioned cor-
rectly.

Vehicle is transferred by ferry or by towing after its
ignition switch is turned to OFF.

Drive the vehicle for a while in the GPS sat-
ellite signal receiving condition.

Screen will not switch to nighttime
mode after the lighting switch is
turned ON.

The daytime screen is selected by the “SWITCH
SCREENS” when the last time the screen dim-
ming setting is done.
Switching between daytime/nighttime screen may
be inhibited by the automatic illumination adjust-
ment function.

Perform screen dimming and select the
nighttime screen by “SWITCH SCREENS”.

Map screen will not scroll in accor-
dance with the vehicle travel.

Current location is not displayed.

Press “MAP” button to display the current lo-
cation.

Vehicle mark will not be shown.

Current location is not displayed.

Press “MAP” button to display the current lo-
cation.

Accuracy indicator (GPS satellite
mark) on the map screen stays
gray.

GPS satellite signal is intercepted because the ve-
hicle is in or behind a building.

Move the vehicle out to an open space.

GPS satellite signal cannot be received because
an obstacle is placed on top of the instrument pan-
el.

Do not place anything on top of the meter dis-
play (instrument panel).

GPS satellites are not visible from current location.

Wait until GPS satellites are visible by mov-
ing the vehicle.

Vehicle location accuracy is low.

Accuracy indicator (GPS satellite mark) on the
map screen stays gray.

Current location is not determined.

Vehicle speed setting by the vehicle speed pulse
has been deviated (advanced or retarded) from
the actual vehicle speed because tire chain is fit-
ted or the system has been used on another vehi-
cle.

Drive the vehicle for a while [for approx. 30
minutes at approx. 30 km/h (19 MPH)] and
the deviation will be automatically adjusted. If
advancement or retard still occur, perform
the distance adjustment by CONFIRMA-
TION/ADJUSTMENT mode of diagnosis
function.

Map data has error or omission. (Vehicle mark is
always deviated to the same position.)

As a rule, an updated map DVD–ROM will be
released once a year.

Symptom

Cause

Remedy

No route is shown.

No road to be searched is found around the des-
tination.

Find wider road (orange road or wider) near-
by and reset the destination and passing
points onto it. Take care of the traveling direc-
tion when there are separate up and down
roads.

Starting point and the destination are too close.

Set the destination at more distant point.

Conditional traffic regulation (day of the week/
time of the day) is set at the area around the cur-

Turn the time-regulating search conditions
OFF. Turn “Avoid regulation time” in the
search conditions OFF.
