Symptom/ error message

Solution

terpret the command correctly.

1. Ensure that the command format is valid.

2. Speak clearly without pausing between words and at a level appropriate to the ambient noise
level.

3. Ensure that the ambient noise level is not excessive, for example, windows open or defrost on.
NOTE:
If it is too noisy to use the phone, it is likely that voice commands will not be recognized.

4. If optional words of the command have been omitted, then command should be tried with these
in place.

The system consistently selects
the wrong voicetag

1. Ensure that the voicetag requested matches what was originally stored. This can be confirmed
by giving the “Addressbook” Directory or Phone Directory command.

2. Replace one of the voicetags being confused with a different voicetag.

Symptom

Solution

System fails to interpret the com-
mand correctly.

2. Ensure that the command is spoken after the tone.

3. Speak clearly without pausing between words and at level appropriate to the ambient noise lev-
el in the vehicle.

4. Ensure that the ambient noise level is not excessive (for example, windows open or defroster
on).
NOTE:
If it is too noisy to use the phone, it is likely that the voice commands will not be recognized.

5. If more than one command was said at a time, try saying the commands separately.

6. If the system consistently fails to recognize commands, the voice training procedure should be
carried out to improve the recognition response for the speaker. See “Speaker adaptation (SA)
mode” earlier in this section. Refer to “OWNER’S MANUAL”.

< SYMPTOM DIAGNOSIS >

NORMAL OPERATING CONDITION

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 if noise is caused and/or changed by engine speed, ignition switch turned to each position, and oper-
ation of each piece of electrical equipment, and then determine the cause.

NOTE:
• CD-R is not guaranteed to play because they can contain compressed audio (MP3, WMA, AAC, M4A) or

could be incorrectly mastered by the customer on a computer.

• Check if 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 DVD

The system consistently selects
the wrong voicetag

1. Ensure that the phone book entry name requested matches what was originally stored. This
can be confirmed by using the “List Names” command.

2. Replace one of the names being confused with a new name.

Symptom

Solution

Symptom

Cause and Counter measure

Cannot play

Check if the CD was inserted correctly.

Check if the CD is scratched or dirty.

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

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

If there is a mixture of music CD files (CD-DA data) and MP3/WMA/AAC/M4A files on a CD, only
the music CD files (CD-DA data) will be played.

Files with extensions other than “.MP3”, “.WMA”, “AAC”, “.M4A”, “.mp3”, “.wma”, “.aac” or “.m4a”
cannot be played. In addition, the character codes and number of characters for folder names and
file names should be in compliance with the specifications.

Check if the disc or the file is generated in an irregular format, This may occur depending on the
variation or the setting of MP3/WMA/AAC/M4A writing applications or other text editing applica-
tions.

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

Check if the CD is protected by copyright.

Disks recorded in live file system format are not supported. (For Microsoft Windows Vista, check
the settings.)

Poor sound quality

Check if 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/AAC/M4A CD, or if it is a multisession disc,
some time may be required before the music starts playing.

Music cuts off or skips

The writing software and hardware combination might not match, or the writing speed, writing
depth, writing width might not match the specifications. Try using the slowest writing speed.

Skipping with high bit rate files

Skipping may occur with large quantities if data such as for high bit rate data.

Move immediately to the next song
when playing

When a non-MP3/WMA/AAC/M4A file has been given an extension of “.MP3”, “.WMA”, “AAC”,
“.M4A” “.mp3”, “.wma”, “.aac” or “.m4a”, or when play is prohibited by copyright protection, the
player will skip to the next song.

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.

Symptom

Possible cause

Possible solution

Names of roads differ between Plan

View and Birdview

™

.

This is because the quantity of the displayed in-
formation is reduced so that the screen does
not become too crowded. There is also a
chance that names of the roads may be dis-
played multiple times, and the names appear-
ing on the screen may be different because of
a processing procedure.

This is not a malfunction.
