● Do not place the Bluetoothா 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 Bluetoothா Audio

Distribution Profile (A2DP, AVRCP).

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 Mi-

crosoft 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.
