Warning!
Due to the different volumes of the external
audio sources, system messages of the
vehicle may be much louder. You may need to
disable these system messages or adjust the
volume of these messages manually.
i The volume of external audio sources is
extremely variable. It is possible that a
device connected as an external audio
source will sound quieter or louder in the
vehicle or that the usual maximum volume
cannot be achieved. On certain devices the
volume can be set separately. In this case,
start at a moderate volume and increase it
slowly. In this way, you can determine
whether the system is capable of playback
without distortion, even at high volume. Switching to media interface
operation
i Starting individual function may take
several minutes, depending on the external
device and the content of the medium, for
example video podcasts.
Do not use software other than the genuine
software for uploading your iPod ®
