A wireless adapter for decoding information from a broadcast signal to which a radio is tuned. The radio emits a local signal that serves to identify the broadcast signal, and a coupling part in the vicinity of the radio responds to the local signal. The coupling part produces a tuning signal in response to the local signal, and the tuning signal is applied to an adapter receiver circuit so that the receiver circuit acquires the broadcast signal to which the radio is tuned. A decoder circuit then decodes information contained in the acquired broadcast signal. In one embodiment, the adapter can be mounted in a vehicle near the vehicle radio. When the radio is tuned to a station that encodes, e.g., RBDS radio text on a sub-carrier of its broadcast signal, the adapter will acquire the station's sub- carrier, and will display the text conveniently and safely.
