From the 2011 MEDIA CENTER 430/430N User Manual page 11:
Connect a supported device into the USB Connector (10)
in order to play music and to copy music and picture files
to the internal hard disk drive.
and page 76 :
It is possible to copy audio files or pictures files to the
radio Hard Disk Drive, or play audio files directly from
the USB device just like a music disc. The USB connector
is covered by a small cover, which protects the connector
from dust or damage.
NOTE: USB devices (e.g., camera memory USB adaptors,
etc.) must comply with the MSD (Mass Storage
Device) standard. This USB terminal can provide power
to the inserted device. The current draw from these
devices must be limited to 500mA or less.
The transfer speed for this USB connector is approximately
two megabytes per second.
MP3 player devices cannot be controlled through the
USB connector. Some player devices save music files in
other formats, which cannot be played in this radio. Some
copy-protected music (e.g., downloads from the internet)
cannot be played on this radio.
Please see your authorized dealer or visit http://
for supported devices.
NOTE: Some MP3 Players do not allow songs to be
copied into other devices.
