Infotainment System
When play enters a new folder,
the display does not automatically
show the new folder name unless
the folder mode has been chosen
as the default display. The new
track name displays.
File System and Naming
The song name that displays is the
song name contained in the ID3 tag.
If the song name is not present in
the ID3 tag, then the radio displays
the file name without the extension
(such as .mp3) as the track name.
Track names longer than
32 characters or four pages are
shortened. Parts of words on the
last page of text and the extension
of the filename do not display.
