ID3, WMA and AAC 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 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.
AAC tags can be added to AAC files, making it possible to record the track title and
artist name in the same way as with ID3 tags.
MP3, WMA and AAC playback
●
• When a device containing MP3, WMA or AAC files is connected, all files in the
USB memory device are checked. Once the file check is finished, the first MP3,
WMA or AAC file is played. To make the file check finish more quickly, we recom-
mend that you do not include any files other than MP3, WMA or AAC files or cre-
ate any unnecessary folders.
• When a USB memory device is connected and the audio source is changed to USB
memory mode, the USB memory device will start playing the first file in the first
folder. If the same device is removed and reconnected (and the contents have not
been changed), the USB memory device will resume play from the same point in
which it was last used.
Extensions
●
If the file extensions .mp3, .wma and .m4a are used for files other than MP3, WMA
and AAC files, they will be skipped (not played).
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, WMA
and AAC 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 trademarks of
Microsoft Corporation in the U.S.A. and other countries.
NOTICE
To prevent damage to the USB memory device or its terminals
■
Do not leave the USB memory device in the vehicle. The temperature inside the vehi-
●
cle may become high.
Do not push down on or apply unnecessary pressure to the USB memory device
●
while it is connected.
Do not insert foreign objects into the port.
