Introduction
“
Media sources
” are audio sources containing audio files on various differ-
ent data media (e.g. CD, memory card, external MP3 player). These audio
files can be played by the radio and navigation system from its correspond-
ing drives or audio input sockets (internal CD player, memory card slot, ME-
DIA-IN interface, AUX-IN, etc.).
The supported file formats listed are collectively referred to below as “audio
files”. A CD containing audio files of these types is referred to as an “audio
data CD”.
