Your iPod just called shotgun.

The latest car audio technology makes it easy to connect and control your iPod seamlessly.

Easy connection.

Connecting your iPod to your car is just as easy as connecting it to your computer. Over 90 percent of new cars sold in the United States have an option for iPod connectivity. And many iPod-ready audio systems use a 30-pin connector cable similar to the one that connects an iPod to your computer.

Instant recognition.

Once connected, your iPod is quickly recognized by your car audio system and added as an audio source.

Access your music.

Audio systems in many newer vehicles have taken a cue from iPod and make it easy to find the right song or audiobook. Browse through on-screen menus to see playlists, artists, albums, even genres and composers.
