RBDS (Radio Data Broadcast System) enables certain functionality1, such as:
- Searches for program types or new broadcasts
- Text information about currently broadcast programs
For example, if news is broadcast, the currently playing sound source will be interrupted so that the news can be heard. The infotainment system will return to the previous sound source when the news broadcast has been completed.
To cancel the announcement, press the 
button on the right-side steering wheel keypad or tap Cancel on the center display. This function can be activated/deactivated in the center display's Settings menu.
