HD Radio® is a subscription-free service.

HD Radio® technology allows an AM or FM radio station to duplicate their traditional analog channel with a matching digital channel. Some FM radio stations subdivide the digital output signal into multiple channels that are not duplicates of the analog channel. These extra multicast channels vary in availability and are called HD2, HD3 and HD4 channels.

The AM/ FM fender-mounted antenna receives radio waves containing metadata (information such as station call letters, artist, album title, song title, and genre) and digital HD Radio® audio. The radio waves are sent through the AM/ FM antenna coaxial cable to the HD Radio® receiver built into the ACM. The metadata is separated from the audio. The metadata is sent to the APIM to be displayed on the FDIM, and the audio is converted into fluctuating AC voltage and sent as left and right analog audio signals to the audio DSP module. The audio DSP module processes the audio signals and sends them to the speakers as fluctuating AC voltage.
