Radio Data System for station information and data services
The Radio Data System (RDS) lets you tune into radio stations without having to remember the frequencies. In standard mode. RDS displays the station name instead of the transmission frequency, facilitating quick and easy tuning. RDS also allows stations to send text messages such as news and station information directly to the radio display. Commonly used in Europe, RDS text is sent out on the same frequency the radio station broadcasts on. You can choose either the basic RDS display (station name) or subscribe to additional text-based services.
