You can control the iPod with your JVC head unit* - to allow you to listen to digital audio via your in-car audio system.
The KS-PD100 interface adapter for iPod features an information display with the same categories and layers as an iPod. Where conventional headunits may not list all the options available on your digital player, the JVC iPod Adapter will list all the options as featured on your iPod display.
The JVC head unit will also navigate through your songlist in a similar style to the iPod clickwheel. Where "up" on the head unit acts like the "menu" button on the iPod, and "down" acts like the "play/pause" button. The Adapter will also recharge the battery of the iPod whilst connected and, when fitted, the unit hides away to save space and obscure from view.
