iPod optimization
To optimise the connection of your
iPod with the Infotainment system
you should carry out the following
simple operations on your iPod:
● Configure the iPod for use as an external disc. Refer to the iPod
user manual
● If the configuration has been made on an Apple computer,
configure it on a Windows
personal computer
● Save the music tracks as audio files compatible with the
Infotainment system
These operations will not
compromise the sound quality or
usability of the iPod tracks.
Playing saved audio files
The Media player detects when a
USB audio device is connected to the USB port and a library is created and
displayed automatically after the
ignition is switched on.
