Related to Telephone
The system should respond correctly to all voice comm ands without difficulty. If problems are encountered, try
the following solutions.
Where the solutions are listed by number, try each soluti on in turn, starting with number 1, until the problem is
resolved.
Symptom Possible cause Possible solution
The system does not
recognize your com-
mand.
or
The system recognizes
your command incor-
rectly The interior of the vehicle is too noisy. Close the windows or have other occupants quiet.
The volume of your voice is too low. Speak louder.
The volume if your voice is too loud. Speak softer.
Your pronunciation is unclear. Speak clearly.
You are speaking before the voice recognition is ready
Press and release “ ” switch on the steering
switch, and speak a command after the tone
sounds.
8 seconds or more have passed after you pressed and
released “ ” switch on the steering switch. Make sure to speak a command within 8 seconds
after you press and release “ ” switch on the
steering switch.
Only a limited range of voice commands is usable for
each screen. Use a correct voice command appropriate for the
current screen.
The fan of the air conditioner is too loud. Lower the fan speed as necessary as voice com-
mand can be recognized more easily.
Symptom/ error message Solution
Displays “CO MMAND NOT REC-
OGNIZED” or the system fails to in-
terpret the comm and 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 li
kely 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”.

AV-208
< 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 c ontain 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 bl ocking
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.

but no sound comes out. Playback of Mix mode Truck 1. (Mix mode: Format in-
cluding Truck 1 with data other than music and Trucks
from Truck 2 with music data.)

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.

NORMAL OPERATING CONDITION
RELATED TO ROUTE CALCULATION AND VISUAL GUIDANCE
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
when you turn on the headlights.
The map does not scroll even when
the vehicle is moving. The current location map screen is not dis-
played.
Press “MAP”.
The vehicle icon is not displayed. The current location map screen is not dis-
played.
Press “MAP”.
The location of the vehicle icon is
misaligned from the actual position. When using tire chains or replacing the tires,
speed calculations based on the speed sensor
may be incorrect. Drive the vehicle for a while [at approximately
30 km/h (19 MPH) for about 30 minutes] to
automatically correct the vehicle icon posi-
tion.
If this does not correct the vehicle icon posi-
tion, contact an INFINITI dealer.
The map data has a mistake or is incomplete
(the vehicle icon position is always misaligned
in the same area). Updated road information will be included in
the next version of the map data.

calculation.
You are not driving on the suggested route. Drive on the suggested route.
Route guidance is set to off. Turn on route guidance.
Route information is not provided for certain types of roads
(roads displayed in gray). This is not a malfunction.
The auto reroute calculation (or
detour calculation) suggests
the same route as the one pre-
viously suggested. Route calculations took priority conditions into consider-
ation, but the same route was calculated.
This is not a malfunction.
A waypoint cannot be added. Five waypoints are already set on the route, including ones
that you have already passed. A maximum of 5 waypoints can be set
on the route. If you want to go to 6 or
more waypoints, perform route calcu-
lations multiple times as necessary.
The suggested route is not dis-
played. Roads near the destination cannot be calculated.
Reset the destination to a main or or-
dinary road, and recalculate the route.
The starting point and destination are too close. Set a more distant destination.
The starting point and destination are too far away. Divide your trip by selecting one or two
intermediate destinations, and per-
form route calculations multiple times.
There are time restricted roads (by the day of the week, by
time) near the current vehicle location or destination. Set [Use Time Restricted Roads] to
off.

passed the first waypoint, the section between the starting
point and the waypoint is deleted. (It may not be deleted de-
pending on the area.)
This is not a malfunction.
An indirect route is suggested. If there are restrictions (such as one-way streets) on roads
close to the starting point or destination, the system may
suggest an indirect route.
Adjust the location of the starting of
the starting point or destination.
The system may suggest an indirect route because route

rote taking into consideration such things as traffic
jams.
The route does not
avoid road section with
traffic information stat-
ing it is closed due to
road construction. The navigation system is designed not to avoid this
event because the actual period of closure may differ
from the declared roadwork period. Observe the actual road condition and follow the
instructions on road for detour when necessary. If
the road closure is for certain, use detour function
and set the detour distance to avoid the closed
road section.
Traffic information dis-
played differs from in-
formation from other
media (e.g. radio). Other media may use different information sources.
Observe the actual road conditions and regula-
