pg. 176 RDS, Automatic tuning

Radio Data System - RDS also referred to as RDS)
The SC-900 radio is equipped with an advanced system allowing information from broadcasters to be transmitted inaudibly together with the audio signal. This information is then decoded by the SC-900 and made available for several new and unique features. The RDS and Radio Data System operates in the FM band only, and the information transmitted is supplied by participating broadcasters. Volvo has no control over the accuracy of the data or information. Please refer to pages 176-181 regarding specific descriptions and operation of these functions. Volvo was among the first to pioneer this technology throughout Europe and it is slowly making its way to North America. Coverage by local broadcasters may be limited at this time, but as the technology and benefits grow, you will find the SC-900 radio ready to advantage of this system.
