Factory Radio Integration for your iPod HY1

The HY1  ishy571 Auxiliary Interface Adapter lets you add a 3.5 mm AUX input to your Hyundai factory radio, giving you an easy way to connect your smartphone, MP3 player, or portable device directly to your vehicle’s sound system.

It provides crystal-clear, distortion-free sound by sending the audio signal directly through your radio’s data port. Unlike FM transmitters or cassette adapters, the HY1 maintains factory sound quality and integrates seamlessly with your existing controls.

Because it’s an OEM-style interface, installation is quick and does not require cutting or splicing wires. Simply plug it into your radio’s CD-changer port, select AUX mode, and enjoy your music through the factory speakers.

How It Works

The HY1 plugs into the factory radio’s CD-changer or external input port. Once connected, your radio recognizes the interface as an auxiliary source.
To activate it, press the AUX or CD button (depending on your model). Then connect your device to the 3.5 mm input and start playback.
Volume, bass, and tone adjustments work normally through your existing radio and controls.

2. Plug the HY1 connector into the XM port on the back.
