. 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.

. 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

. 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.

STREAMING AUDIO
(models with navigation system) GUID-384085FE-4107-49E0-ABDF-8432D24FAAB8
Your 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.
