The FM receiver chip in mobile devices uses the cord from your headphones or an audio cable as an antenna. If you do not have wired headphones or a cable plugged in, FM stations in your area that do not have an Internet stream available will appear dimmed in the Live Guide and Genre Guide, and there will be a headphones icon on top of the station's logo or album art. This indicates that in order to listen to this station, you need to plug in headphones or an audio cable.
