audi symphony radio
Audi Symphony Radio is an audio system available in some Audi models. Most versions of the system include an AM/FM tuner with Radio Data System (RDS) that can display station, artist, and track information, as well as a CD player. Some models include the ability to play MP3, AAC, and WMA playback from a CD while others have an SD card slot. Most systems come with either speed-dependent volume control or Graduated Audio Level Adjustment (GALA) to ensure the optimal volume level. A few models also include an aux-in jack and SIRIUS Satellite Radio.
