The CD-IU230V interface cable lets you connect your iPod to Pioneer's AVIC-F700BT or AVIC-F900BT in-dash navigation receivers, so you can access your iPod with voice commands or with the receiver's touchscreen controls. Pioneer's VoiceBox Conversational Control system lets you ask for playlists, artists, genres, and more, or you can touch the receiver's screen to find the iPod content you're looking for. Just connect the cable to your iPod, plug it into the receiver, and enjoy.
