04 MUSIC
USB player
Insert the uSB memory stick in the uSB player or connect the uSB
peripheral device to the uSB port using a suitable cable
(not supplied).
the system builds playlists (in temporary memory), an operation
which can take from a few seconds to several minutes at the first
connection.
Reduce the number of non-music files and the number of folders to
reduce the waiting time.
the playlists are updated every time the ignition is switched off or
connection of a uSB memory stick. However, the audio system
memorises these lists and if they are not modified, the loading time
will be shorter.
