< SYMPTOM DIAGNOSIS >

[NAVIGATION (SINGLE MONITOR)]

NORMAL OPERATING CONDITION

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, 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.

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.
