Do not keep a USB flash memory
device in the vehicle. Direct
sunlight and high heat will damage
it.
We recommend backing up your
data before playing a USB flash
memory device.
Some devices cannot be powered
or charged via the USB adapter. If
this is the case, use the accessory
adapter to supply power to your
device.
Depending on the type and
number of files, it may take some
time before they begin to play.
Depending on the software the
files were made with, it may not be
possible to play some files, or
display some text data.
Depending on the type of
encoding and writing software
used, there may be cases where
character information does not
display properly.
