Abstract
According to a user's recording instruction, a navigation apparatus acquires reception data (music information and identification information) from a satellite digital radio apparatus on a tune basis and records the data on a hard disk. After the recording is complete, the navigation apparatus uses a size of the reception data recorded on the hard disk to determine whether or not the recording is interrupted in the middle of a tune. When the recording is interrupted, the navigation apparatus registers the tune's identification information to an interrupted recording list. The navigation apparatus then acquires identification information about a tune being received from the satellite digital radio apparatus. When the interrupted recording list registers the identification information, that is, the recording-interrupted music is rebroadcast, the navigation apparatus acquires reception data from the satellite digital radio apparatus and re-records it on the hard disk.
