• Playback of discs recorded on a personal com-

puter may not be possible, depending on the

application settings and the environment.

Please record with the correct format. (For

details, contact the manufacturer of the appli-

cation.)

• Playback of CD-R/CD-RW discs may become

impossible with direct exposure to sunlight,

high temperatures, or depending on the stor-

age conditions in the vehicle.

• Titles and other text information recorded on a

CD-R/CD-RW disc may not be displayed by this

product (in the case of audio data (CD-DA)).

• If you insert a CD-RW disc into this product,

time to play back will be longer than when you

insert a conventional CD or CD-R disc.

• Read the precautions with CD-R/CD-RW discs

before using them.

MP3 files

• When naming an MP3 file, add the corre-

sponding filename extension (.mp3).

• This navigation system plays back files with the

filename extension (.mp3) as MP3 files. To pre-

vent noise and malfunctions, do not use this

extension for files other than MP3 files.

• MP3 is short for MPEG Audio Layer 3 and

refers to an audio compression technology

standard.

• This product allows playback of MP3 files on

CD-ROM, CD-R and CD-RW discs. Disc record-

ings can be played back if they are compatible

with level 1 and level 2 of ISO9660 and with the

Romeo and Joliet file system.

• It is possible to play back multi-session com-

patible recorded discs.

• MP3 files are not compatible with packet write

data transfer.

• The maximum number of characters are 32

characters including extension (.mp3). But the

navigation system incorporates the propor-

tional font. Therefore, the number of the char-

acters which you can display varies according

to the width of each character.

• When playing discs with MP3 files and audio

data (CD-DA) such as CD-EXTRA and MIXED-

MODE CDs, both types can be played only by

switching mode between MP3 and CD-DA.

• The folder selection sequence for playback and

other operations is the writing sequence used

by the writing software. For this reason, the

expected sequence at the time of playback

may not coincide with the actual playback

sequence. However, there also are some writ-

ing software that permit the setting of the play-

back order.

• Some audio CDs contain tracks that merge

into one another without a pause. When these

discs are converted to MP3 files and burned to

a CD-R/CD-RW/CD-ROM, the files will be

played back on this player with a short pause

between each one, regardless of the length of

the pause between tracks on the original audio

CD.

• Files are compatible with the ID3 Tag Ver. 1.0

and Ver. 1.1 formats for display of album (disc

title), track (track title) and artist (track artist).

• The emphasis function is valid only when MP3

files of 32, 44.1 and 48 kHz frequencies are

played back. (16, 22.05, 24, 32, 44.1, 48 kHz

sampling frequencies can be played back.)

• There is no m3u playlist compatibility.

• There is no compatibility with the MP3i (MP3

interactive) or MP3 PRO formats.

• The sound quality of MP3 files generally

becomes better with an increased bit rate. This

product can play recordings with bit rates from

8 kbps to 320 kbps, but in order to be able to

enjoy sound of a certain quality, we recom-

mend using only discs recorded with a bit rate

of at least 128 kbps.
