Honda Goldwing GPS Imput is an electrical interface between your GPS, cell phone, laser/radar detector, or any other device that produces audio and has a 3.5mm output jack. Plugged into your device, it routes the audio directly into your Goldwing's intercom system, allowing you to hear the device just as if it were a third passenger talking! If you are listening to the radio, the radio will mute automatically when the GPS makes an announcement, just as it would if you or a passenger began talking.
