About ID3/WMA tags
In MP3/WMA files, you can enter textual attribute information known as
ID3 tags/WMA tags to save information such as track titles and artist
names.
This unit supports ID3v.1.0, 1.1, 2.2, 2.3 and 2.4 tags. This unit supports
the ISO 8859-1, 2, 5 and 7 codes only. Use only the ISO 8859-1, 2, 5 or 7
codes to record tags. If characters not included in ISO 8859-1, 2, 5 or 7
codes are recorded, they may not be readably displayed.
This unit supports the WMA tag ASF revision (v1.20.02). WMA tags using
only Unicode are supported. Always use Unicode characters to enter
the information.
* When Ver. 1.x and Ver. 2.x of the ID3 tags both exist, precedence is given to
Ver. 2.x.

About the supported media types
You can play MP3/WMA files recorded on a CD-ROM, CD-R or CD-RW
disc. Compared to the CD-ROM media commonly used for music discs,
CD-R and CD-RW discs are fragile in high temperature and high
humidity environments. It may not be possible to play some CD-R/
CD-RW discs. Fingerprints or scratches on a disc may prevent playback
or cause skipping during playback.
Some CD-R/CD-RW discs may deteriorate if left inside a vehicle for a
long time.
We recommend that you store UV-sensitive CD-R and CD-RW discs in
shield cases.
