PROBLEM TO BE SOLVED: To provide an FM multiplex broadcast receiver which can receive FM multiplex data included in broadcast waves of different receiving frequencies while switching. SOLUTION: In order to obtain VICS information or DGPS information by receiving an FM multiplex broadcast of desired receiving frequency, an FM multiplex broadcast receiver 1 comprises a front end 12, an intermediate amplifying/FM detecting circuit 14, a filter circuit 16, an LMSK demodulation circuit 18, an error detecting/correcting circuit 22, a CPU 24, and a selection circuit 30. When a DGPS information receiving command is delivered at a specified timing from a navigation unit 2 through an I/O interface section 28, the CPU 24 makes a switching from VICS receiving frequency to DGPS receiving frequency by delivering a command to the selection circuit 30. |
