This DF adapter lets you connect your portable music player directly to your compatible Honda/Acura factory radio. Just plug the adapter cable into your radio's CD changer input, mount the interface box, and you're ready to listen to your tunes.And the news gets better — if you also have another sound source you want to hook up to your Honda's sound system, the DF-xxx adapter provides a second set of connections for an iPod, satellite radio tuner, or DVD player. You can switch between sources with your factory radio controls.
