After switching the destination specification, it is determined whether or not the current mode is the tuner mode in FIG. 12 (step S801). If the mode is not the tuner mode, the title of the disc is called (step S80).
2). If it is in the tuner mode, the storage format of the RAM 8 in which the same frequency data as the frequency data of the currently receiving broadcasting station is registered is searched, and the title registered in the searched storage format is called (step S803). . Next, it is determined whether or not the title exists (step S804). If the title exists, it is determined whether or not the destination specification data of the storage format in which the title is registered matches the current destination specification data (step S805). If the destination specification data matches, the title is displayed on the display unit 6 (step S806).

If there is no title in step S804, a non-title display notifying that there is no title is displayed on the display unit 6 (step S807). If the destination specification data does not match in step S805, the process proceeds to step S807.

According to the audio apparatus of the above embodiment, even if a broadcast station having the same frequency data as the frequency data registered in the storage format of the RAM 8 is received, the broadcast station is determined based on the destination specification data of each frequency data. Since it is determined whether the registered frequency data is the same as the frequency data currently being received, it is possible to reliably prevent a title from being erroneously displayed when the same frequency data is received by a broadcasting station.
