NORMAL OPERATING CONDITION

Related to Item Choice

The system should respond correctly to all voice commands without difficulty. If problems are encountered, fol-
low the solutions given in this guide for the appropriate error.
Where the solutions are listed by number, try each solution in turn, starting with number one, until the problem
is resolved.

Related to Telephone

The system should respond correctly to all voice commands without difficulty. If problems are encountered, try
the following solutions.
Where the solutions are listed by number, try each solution in turn, starting with number 1, until the problem is
resolved.

RELATED TO AUDIO

• The majority of the audio malfunctions are the result of outside causes (bad CD/cassette, electromagnetic

interference, 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) 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.

Symptom/ error message

Solution

Displays “COMMAND NOT REC-
OGNIZED” or the system fails to in-
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.

1. Ensure that the command is valid. 

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”.

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.

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 

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 files on a CD, only the 
music CD files (CD-DA data) will be played. 

Files with extensions other than “.MP3”, “.WMA”, “.AAC” “.mp3”, “.wma”, or “.aac” 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 writing applications or other text editing applications.

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 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 file has been given an extension of “.MP3”, “.WMA”, “”.AAC“.mp3”, 
“.wma”, or “.aac” 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.

Poor reception only from a certain 
radio broadcast station.

Check incoming radio wave signal strength of applicable broadcast station.

Buzz/rattle sound from speaker

The majority of rattle sounds are not indicative of an issue with the speaker, usually something 
nearby the speaker is causing the rattle.

Symptom

Possible cause

Possible solution

Not working as operated

Some operations may be rejected or may not function 
as intended because of the manufacturer's intent, de-
pending on DVD. 

This is not a malfunction.

Operation not accepted

If a requested operation is prohibited, then a message 
is displayed on the screen. (Message display depends 
on DVD.)

This is not a malfunction.

Symptom

Possible cause

Possible solution

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.

The vehicle icon is not displayed in 
the correct position.

The vehicle was transported after the ignition 
switch was pressed off, for example, by a ferry 
or car transporter.

Drive the vehicle for a while on a road where 
GPS signals can be received.

The position and direction of the vehicle icon 
may be incorrect depending on the driving en-
vironments and the levels of positioning accu-
racy of the navigation system.

This is not a malfunction. Drive the vehicle for 
a while to automatically correct the position 
and direction of the vehicle icon.

When the vehicle is traveling on a 
new road, the vehicle icon is located 
on another road nearby.

Because the new road is not stored in the map 
data, the system automatically places the vehi-
cle icon on the nearest road available.

Updated road information will be included in 
the next version of the map data.

The screen does not switch to the 
night screen even after turning on 
the headlights.

The daytime screen was set the last time the 
headlights were turned on.

Set the screen to the night screen mode using 
<Day/Night> when you turn on the headlights.
