There is the additional 3.5mm AUX jack for the alternative audio sources such as MP3 player, DVD,
GPS, XM and etc. You can use it by simply plugging in one of those devices. We recommend that you
unplug the iPod/iPhone from the dock connector if you are using the AUX input on GROM-iPD2 adapter.
If you don't unplug the iPod/iPhone and connect the 3.5mm audio source at the same time some sound
interference may occur.
