[AUDIO WITHOUT NAVIGATION]

AUDIO SYSTEM SYMPTOMS

• When customers contact concerning Bluetooth

™

compatible cell phone malfunction for the first time, always

suggest customers to update cellular phone software if possible.

• Check that customer cellular phone is compatible on the published list. The dealer should contact its RBU/

NSC for the list.

• Take note of any exceptions that the list may detail, i.e. no ringing tone or no phonebook transfer etc. If the

customer phone is not listed then its full function cannot be guaranteed. NISSAN should not replace the
audio unit if the cell phone does not appear on the list or the cell phone is operating as described on the list
e.g. no ringing tone, no phonebook transfer etc.

• Take note of any exceptions to other phones made by the same manufacturer as the customers. Any excep-

tions on one model by a specific manufacturer may be common to all models made by that manufacturer.

Simple Check for Bluetooth

™

Communication

If cellular phone and audio unit cannot be connected with Bluetooth

™

communication, following procedure

allows the technician to judge which device has malfunction.

Turn on a cellular phone, not connecting Bluetooth

™

communication.

Start CONSULT-III, then start Windows

Set CONSULT-III near a cellular phone.

When operated Bluetooth

™

registration by cellular phone, check

if CONSULT-III

would be displayed on the device name.

(If other Bluetooth

™

device is located near cellular phone, a

name of the device would be displayed also.)
NOTE:
*:Displayed device name is “NISSAN-

”.

• If no device name is displayed, cellular phone is malfunction.

Repair the cellular phone first, then perform diagnosis.

• If CONSULT-III is displayed on device name, cellular phone is nor-

mal

. Perform diagnosis as per the following table.

: There is no 100% guarantee that cellular phone operates all

functions on audio unit. Different phone manufacturers implement Bluetooth

™

in different ways. Phones on

Supported Phone List are tested and any minor exceptions are listed.

NORMAL OPERATING CONDITION

NORMAL OPERATING CONDITION

Description

INFOID:0000000006414394

RELATED TO AUDIO

• 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 malfunctioning.

Check that noise is caused and/or changed by engine speed, ignition switch turned to each position, and
operation of each piece of electrical equipment. Then determine the cause.

NOTE:
• CD-R is not guaranteed to play because they can contain compressed audio (MP3, WMA) or could be incor-

rectly mastered by the customer on a computer.

• Check that the CDs carry the Compact Disc Logo. If not, the disc is not mastered to the red book Compact

Disc Standard and may not play.

Noise resulting from variations in field strength, such as fading noise and multi-path noise, or external noise from trains and other
sources, is not a malfunction.

NOTE:

• Fading noise: This noise occurs because of variations in the field strength in a narrow range due to mountains 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.

RELATED TO TELEPHONE

Symptoms

Cause and counter measure

Cannot play

Check that the CD was inserted correctly.

Check that the CD is scratched or dirty.

Check that there is condensation inside the player, and if there is, wait until the condensation is
gone (about 1 hour) before using the player.

The player will play correctly after it returns to the normal temperature if there is a temperature
increase error.

Only the music CD files (CD-DA data) will be played if there is a mixture of music CD files (CD-
DA data) and MP3/WMA files on a CD.

Files with extensions other than “.MP3”, “.WMA”, “.mp3”, or “.wma” cannot be played.

Check that the finalization process, such as session close and disc close, is done for the disc.

Check that the CD is protected by copyright.

Poor sound quality

Check that the CD is scratched or dirty.

It takes a relatively long time before
the music starts playing.

If there are many folder or file levels on the MP3/WMA CD, or if it is a multisession disc, some
time may be required before the music starts playing.

The songs do not play back in the
desired order.

The playback order is the order in which the files were written by the software, so the files might
not play in the desired order.

Symptoms

Cause and counter measure

Intermittent voice turbulence occurs be-
tween buildings.

Surrounded by buildings, cell phones may have a poor reception due to radio waves
irregular reflection or interception.

Noise interference occurs under the rail-
road overpass or near high-tension wires,
traffic lights, or neon signs.

Noise waves from these may be mixed into radio waves.

Booming noises are mixed into audio.

Radio waves from the cell phone may be mixed into audio.

No sound can be heard:
• Voice from the party on the other end of

the line cannot be heard.

• No ring tone.

• Check that the key switch is not set to ON or ACC.
• Check that sound volume (VOL) is not set to minimum.

• Check that the connection of Bluetooth

™

is normal.

• Adjust cell phone ring tone and volume. Volume levels of ring tone and voice on the

phone depend on the volume setting of the cell phone, according to the model.

NORMAL OPERATING CONDITION

AV-37

< SYMPTOM DIAGNOSIS >

[AUDIO WITHOUT NAVIGATION]

Voice cannot be transmitted to the party on
the other end of the line.

Check that the connection of Bluetooth

™

is normal.

Telephone call does not get through.

• Check that the cell phone is not locked.

• Check that the connection of Bluetooth

™

is normal.

• Check that the telephone call is made in the area within the telecommunications car-

rier service area.

• Check that the area is not a blind area.

The party on the other end of the line hears
noises while talking on a hand-held cell
phone.

The party on the other end of the line may hear noises depending on where the cell
phone is placed.

Bluetooth

™

has a slow connection after ig-

nition switch ON.

Some models take time for standby.

Sound level of voice is different from that of
ringing sounds or ring tone.

This model allows separate settings for sound levels of ringing sounds, ring tone, and
voice.

The number of electric field reception bars
of the audio unit is different from that of the
cell phone. Or telephone call does not get
through even when transmitting with the re-
ception bar displayed.

Specifications regarding the number of electric field reception bars differ from cell
phone to cell phone. (Reception bar of the audio unit is the guideline.)

The party on the other end of the line hears
muffled sounds while talking on the phone.

Ambient sounds through the microphone make muffled sounds after conversion pe-
culiar to digital devices.
