.Some characters used in other lan-
guages (Chinese, Japanese, etc.) are
not displayed properly on the vehicle
center screen. Using English language
characters with a USB device is recom-
mended.
. Do not connect a USB device if a
connector or cable is wet. Allow the
cable and/or connectors to dry com-
pletely before connecting the USB
device. If the connector is exposed to
fluids other than water, evaporative
residue may cause a short between
the connector pins.
. Large video podcast files cause slow
responses in an iPod
®. The vehicle
center display may momentarily black
out, but it will soon recover.
. If an iPod
®automatically selects large
video podcast files while in the shuffle
mode, the vehicle center display may
momentarily black out, but it will soon
recover.
. Audiobooks may not play in the same
order as they appear on an iPod
®.
. An iPod nano®(1st Generation) may
remain in fast forward or rewind mode
if it is connected during a seek opera-
tion. In this case, please manually reset the iPod
®.
. An iPod nano®(2nd Generation) will
continue to fast forward or rewind if it
is disconnected during a seek opera-
tion.
. An incorrect song title may appear when
the Play Mode is changed while using
the iPod nano

Compressed Audio Files (MP3/
WMA/AAC)
GUID-47EB1CBC-EA75-4271-9A35-A2D303CDA119
Explanation of terms:GUID-D73A39BF-43C8-459F-9C24-47B7F579C407. MP3 —MP3 is short for Moving Pictures
Experts Group Audio Layer 3. MP3 is
the most well known compressed
digital audio file format. This format
allows for near “CD quality”sound, but
at a fraction of the size of normal audio
files. MP3 conversion of an audio track
can reduce the file size by approxi-
mately a 10:1 ratio (Sampling: 44.1
kHz, Bit rate: 128 kbps) with virtually
no perceptible loss in quality. The
compression reduces certain parts of
sound that seem inaudible to most
people. .
WMA —Windows Media Audio (WMA) is
a compressed audio format created by
Microsoft as an alternative to MP3. The
WMA codec offers greater file compres-
sion than the MP3 codec, enabling
storage of more digital audio tracks in
the same amount of space when
compared to MP3s at the same level
of quality.
. AAC/M4A —Advanced Audio Coding
(AAC) is a lossy audio compression
format. Audio files that have been
encoded with AAC are generally smaller
in size and deliver a higher quality of
sound than MP3.
. Bit rate —Bit rate denotes the number
of bits per second used by a digital
music file. The size and quality of a
compressed digital audio file is deter-
mined by the bit rate used when
encoding the file.
. Sampling frequency —Sampling fre-
quency is the rate at which the samples
of a signal are converted from analog to
digital (A/D conversion) per second.
. Multisession —Multisession is one of
the methods for writing data to media.
Writing data once to the media is called
a single session, and writing more than

Explanation of terms:GUID-D73A39BF-43C8-459F-9C24-47B7F579C407.DivX®- DivX®refers to the DivX®codec
owned by DivX, Inc. used for a lossy
compression of video based on MPEG-
4.
. AVI - AVI stands for Audio Video
Interleave. It is a standard file format
originated by Microsoft Corporation. A
“.divx” encoded file can be saved into
the “.avi” file format for playback on
this system if it meets the requirements
stated in the table in this section.
However, not all the “.avi”files are
playable on this system since different
encodings can be used than the DivX
®
codec.
. ASF - ASF stands for Advanced Systems
Format. It is a file format owned by
Microsoft Corporation. Note: Only “.
asf” files that meet the requirements
stated in the table in this section can
be played.
. Bit rate —Bit rate denotes the number
of bits per second used by a digital
video file. The size and quality of a
compressed digital audio file is deter- mined by the bit rate used when
encoding the file.

(models with navigation system)
GUID-384085FE-4107-49E0-ABDF-8432D24FAAB8Your INFINITI is equipped with Bluetooth®
Streaming Audio. If you have a compatible
Bluetooth®device with streaming audio
(A2DP profile), you can set up the wireless
connection between your Bluetooth
®de-
vice and the in-vehicle audio system. This
connection allows you to listen to the
audio from the Bluetooth
®device using
your vehicle speakers. It also may allow
basic control of the device for playing and
skipping audio files using the AVRCP
Bluetooth
®profile. All Bluetooth®Devices
do not have the same level of controls for
AVRCP. Please consult the manual for your
Bluetooth
®Device for more details.
Once your Bluetooth®device is connected
to the in-vehicle audio system, it will
automatically reconnect whenever the de-
vice is present in the vehicle and you select
Bluetooth
®Audio from your audio system.
You do not need to manually reconnect for
each usage.
Wireless LAN (Wi-Fi) and the Bluetooth
®
functions share the same frequency band
(2.4 GHz). Using the Bluetooth®and the
wireless LAN functions at the same time
may slow down or disconnect the commu- nication and cause undesired noise. It is
recommended that you turn off the wire-
less LAN (Wi-Fi) when using the Bluetooth
®
functions.
