Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Dab Tuner: Notes
DAB tuners provide two frequency ranges for data transfer. The L band (1452 MHz to 1492 MHz) and band III (174 MHz to 240 MHz). The data is transmitted digitally to the vehicle in specific channels within the L band and band III. Each channel contains only one ensemble, which in turn contains the radio stations and additional information regarding the radio stations.
Broadcasting station structure for DAB tuners:
- Ensemble 1
- Service 1
- Service 2
- Subservice 1
- Subservice 2
- Subservice 3
- Service 3
- Service 4
- Service 5
The DAB tuner can cover 12 ensembles. One ensemble comprises up to 15 services. The service is comparable with an AM/FM station. A service can contain audio data or information. The subservices offered for the selected service are displayed. In the subservices, for example, the artist, album name and song title are transferred. Alternatively, more audio data can be transferred via the subservices.
