HD Radio™ broadcasting is the new, digital standard for AM and FM radio stations. Across the United States, over 1300 AM/FM stations have upgraded to HD Radio technology, with over 600 of the FM stations also offering new, HD Radio-only "multicast" channels, vastly increasing programming choice. HD Radio stations are broadcast in crystal-clear digital sound and offer innovative data services, such as song artist and title scrolling across the screen. HD Radio is totally subscription free from your local AM and FM radio stations, once your car is equipped with an HD Radio receiver.
