Bluetoothstreaming audio (if so
equipped)
● Some Bluetooth audio devices may not be
recognized by the in-vehicle audio system.
● It is necessary to set up the wireless con-
nection between a compatible Bluetooth
audio device and the in-vehicle Bluetooth
module before using the Bluetooth audio.
● Operating procedure of the Bluetooth au-
dio will vary depending on the devices. Make
sure how to operate your audio device be-
fore using it with this system.
● The Bluetooth audio may be stopped under
the following conditions:
● Receiving a call on the Hands-Free
Phone System.
● Checking the connection to the hands-
free phone.
● Do not place the Bluetooth audio device in
an area surrounded by metal or far away from
the in-vehicle Bluetooth module to prevent
tone quality degradation and wireless con-
nection disruption.
● While an audio device is connected through
the Bluetooth wireless connection, the bat-
tery power of the device may discharge
quicker than usual. ●
This system supports the Bluetooth Audio
Distribution Profile (A2DP, AVRCP) .BLUETOOTH is a

CD or USB with Compressed Audio
Files (models without Navigation
System)
The file types supported by this system are MP3
and WMA.
Explanation of terms:
● 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 from CD-ROM can reduce the
file size by approximately a 10:1 ratio with
virtually no perceptible loss in quality. MP3
compression removes the redundant and
irrelevant parts of a sound signal that the
human ear doesn’t hear. ●
WMA — Windows Media Audio (WMA)* is a
compressed audio format created by Micro-
soft 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.
● 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 determined by the bit rate used
when encoding the file.
● Sampling frequency — Sampling frequency
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 once is called
a multisession.
● ID3/WMA Tag — The ID3/WMA tag is the
part of the encoded MP3 or WMA file that
contains information about the digital music
file such as song title, artist, encoding bit
rate, track time duration, etc. ID3 tag infor-
mation is displayed on the Artist/song title
line on the display.

CD, DVD or USB with Compressed
Audio Files (models with Navigation
System)
The file types supported by this system are MP3,
WMA, AAC/M4A and ATRAC3.
Explanation of terms:● 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 ap-
proximately 10:1 ratio (Sampling: 44.1 kHz,
Bit rate: 128 kbps) with virtually no percep-
tible loss in quality. The compression re-
duces certain parts of sound that seem in-
audible to most people.
● WMA — Windows Media Audio (WMA) is a
compressed audio format created by Micro-
soft 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/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.
● ATRAC3, ATRAC3 Plus — Adaptive Trans-
form Acoustic Coding (ATRAC) is a lossy
audio compression format developed by
Sony.
● 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 determined by the bit rate used
when encoding the file.
● Sampling frequency — Sampling frequency
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

data once to the media is called a single
session, and writing more than once is called
a multisession. ●
ID3/WMA Tag — The ID3/WMA tag is the
part of the encoded MP3 or WMA file that
contains information about the digital music
file such as song title, artist, album title,
encoding bit rate, track time duration, etc.
ID3 tag information is displayed on the
Album/Artist/Track title line on the display.
