Separate USB connection
In addition to the USB connection on the Media Interface, there is another USB connection in the glove box. This connection can also be used to play audio files.
Electrical consumption at this connection must not exceed a continuous current of 500 mA. If the electrical consumption is higher, use a separate source to provide power for the USB device (e.g. 12 V power supply).
To select music from the USB port as
the audio source: select Audio by sliding
and turning
the COMAND
controller and press 
to confirm.
The audio menu appears.
Select USB and press to
confirm.
