USB device connection
When connecting a USB device, make
sure that the connector is pushed all the
way into the port.
Do not leave the USB device for long
periods of time in places inside the vehi-
cle where the temperature can rise too
high.
Back up any important data beforehand.
We cannot accept responsibility for any
lost data.
It is recommended not to connect a USB
device that contains data files other than
MP3/WMA/AAC format.
We recommend against use of USB
devices that are non-standard shape
such as key chains, mobile phone
accessories, etc. which may damage or
stress the connection between USB
device and Socket terminal.
Always close the USB socket terminal
when not in use, since entry of foreignmaterial, dust, water, conductive liquids
may damage the audio system or USB
device.
Device such as MP3 player/Mobile
phone/digital camera may not be rec-
ognized by the audio system for playing
music.
Recording MP3/WMA/AAC
files on a USB device
Playback or display may not be possible
depending on the type of USB device in
use or the condition of the recording.
Depending on the connected USB mem-
ory, the files may be played in different
order from the order that the files were
stored.
During initialization, the reading time of
USB device may vary depending upon
factors such as file structure, size and
contents other than music files.
When files recorded contains VBR (vari-
able bit rate), during playback, fast-for-
ward or reverse operation are done.
The sound quality of MP3/WMA/AAC
files generally improves with higher bit
rate in order to achieve good sound qual-
ity recording with CBR 9continuous bit
rate) of at least 128kbps is recom-
mended.
