•
Audiobooks may not play in the same order as
they appear on an iPod.
• Large video files cause slow responses in an
iPod. The vehicle centre display may momen-
tarily black out, but will soon recover.
• If an iPod automatically selects large video files
while in the shuffle mode, the vehicle centre dis-
play may momentarily black out, but will soon
recover.

• Some Bluetooth® audio devices may not be
used with this system. For detailed information
about Bluetooth® audio devices that are avail-
able for use with this system, contact an ap-
proved dealer or qualified workshop.
• Before using
aBluetooth® audio system, the ini-
tial registration process for the audio device is
necessary.
• Operation of the Bluetooth® audio system may
vary depending on the audio device that is con-
nected. Confirm the operation procedure before
use.
• The playback of Bluetooth® audio will be paused
under the following conditions. The playback will
be resumed after the following conditions are
completed.

The in-vehicle antenna for Bluetooth® communi-
cation is built in the system. Do not place the
Bluetooth® audio device in an area surrounded
by metal, far away from the system or in
anarrow
space where the device closely contacts the
body or the seat. Otherwise, sound degradation
or connection interference may occur.
• While
aBluetooth® audio device is connected
through the Bluetooth® wireless connection, the
battery power of the device may discharge
quicker than usual.

Compact Disc (CD)/USB device with
MP3/WMA/AAC (where fitted)
Terms:
• MP3
—MP3 is short for Moving Pictures Ex-
perts 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
af raction of the size of normal audio files. MP3
conversion of an audio track from CD can re-
duce the file size by approximately 10:1 ratio
(Sampling: 44.1 kHz, Bit rate: 128 kbps) with
virtually no perceptible loss in quality. MP3 com- pression removes the redundant and irrelevant
parts of
asound signal that the human ear
doesn’t hear.
• WMA
—Windows Media Audio (WMA) is a
compressed audio format created by Microsoft
as an alternative to MP3. The WMA codec offers
greater file compression 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 (where fitted)
—Advanced Audio Coding
(AAC) is acompressed audio format. AAC of-
fers greater file compression than MP3 and en-
ables music file creation and storage at the same
quality as MP3.
• Bit rate
—Bit rate denotes the number of bits
per second used by adigital music files. The size
and quality of acompressed digital audio file is
determined by the bit rate used when encoding
the file.
• Sampling frequency
—Sampling frequency is
the rate at which the samples of asignal are con-
verted from analog to digital (A/D conversion)
per second.
• Multisession
—Multisession is one of the meth-
ods for writing data to media. Writing data once
to the media is called asingle session, and writ-
ing more than once is called amultisession.
