Since a full MP3 CD could hypothet-
ically include thousands of MP3 files,
a 999 music pieces limit is imposed by
the system. If the user inserts a MP3
CD which has more than 999 tracks
(files) in it, then only the first 999 files
will be considered and a 7-second
warning will be displayed fig. 27
"Warning: the system will manage on-
ly the first 999 tracks on the MP3
CD". This warning will be closed after
set time or upon pressing "ENTER"
15-fig. 1 or "ESCAPE" 13-fig. 1.
Only one Playlist for each MP3 CD
can be managed. Trying to create a
second playlist on the same CD you
will overwrite the existent one.

CONNECT Nav+ allows storing a
max. number of 10 playlists; when
reaching the last one admitted (when
trying to insert the 11th MP3 CD) the
oldest playlist will be overwritten; the
display will show the following mes-
sage: "10 Playlists have already been
stored. Do you want to overwrite the
oldest?".
When a MP3 CD is inserted, CON-
NECT Nav+ system checks the pres-
ence of a stored playlist coupled with
the CD.
If one of the 10 "known" CDs is de-
tected, playing starts automatically ac-
cording to the preset sequence. If no
playlist coupled to the inserted MP3
CD is found, then playing starts from
the first file on the CD.
If recorded MP3 CD was not sam-
pled at right frequency, playback is im-
mediately stopped and the display
F0C4036g
shows the following message: "The
current track was sampled with a for-
mat which is not compatible with the
reader. It cannot be read by the sys-
tem" fig. 28.
