●MP3 and WMA files
MP3 (MPEG Audio LAYER 3) is a standard audio compression format.
Files can be compressed to approximately 1/10 of their original size using
MP3 compression.
WMA (Windows Media Audio) is a Microsoft audio compression format.
This format compresses audio data to a size smaller than that of the MP3
format.
There is a limit to the MP3 and WMA file standards that can be used and to
the media/formats on which the files are recorded.
●MP3 file compatibility
• Compatible standards
MP3 (MPEG1 AUDIO LAYERII, III, MPEG2 AUDIO LAYERII, III,
MPEG2.5)

MPEG1 AUDIO LAYERII, III: 32, 44.1, 48 (kHz)
MPEG2 AUDIO LAYERII, III: 16, 22.05, 24 (kHz)
MPEG2.5: 8, 11.025, 12 (kHz)
• Compatible bit rates (compatible with VBR)
MPEG1 AUDIO LAYERII, III: 32-320 (kbps)

Interior features
●ID3 and WMA tags
ID3 tags can be added to MP3 files, making it possible to record the track
title, artist name, etc.
The system is compatible with ID3 Ver. 1.0, 1.1, and Ver. 2.2, 2.3, 2.4 ID3
tags. (The number of characters is based on ID3 Ver. 1.0 and 1.1.)
WMA tags can be added to WMA files, making it possible to record the
track title and artist name in the same way as with ID3 tags.
●MP3 and WMA playback
When a device containing MP3 or WMA files is plugged in, all files in the
USB memory device are first checked. Once the file check is finished, the
first MP3 or WMA file is played. To make the file check finish more quickly,
we recommend you do not write in any files other than MP3 or WMA files
or create any unnecessary folders.
●Extensions
If the file extensions .mp3 and .wma are used for files other than MP3 and
WMA files, they will be mistakenly recognized and played as MP3 and
WMA files. This may result in large amounts of interference and damage
to the speakers.
●Playback
• To play MP3 files with steady sound quality, we recommend a fixed bit
rate of at least 128 kbps and a sampling frequency of 44.1 kHz.
• There is a wide variety of freeware and other encoding software for
MP3 and WMA files on the market, and depending on the status of the
encoding and the file format, poor sound quality or noise at the start of
playback may result. In some cases, playback may not be possible at
all.
• Microsoft, Windows, and Windows Media are the registered trade-
marks of Microsoft Corporation in the U.S.A. and other countries.
CAUTION
■Caution while driving
