CONNECT NAV+
Since a full MP3 CD could hypothet-
ically include many 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. 25“Warning: the
system will manage only the first 999
tracks on the MP3 CD”; This warn-
ing will be closed after set time or up-
on pressing the knob 15-fig. 1or
“ESC” 14-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 (whentrying 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
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. 26.IMPORTANTTechnical data and
