PROBLEM TO BE SOLVED: To validate a NAVI(navigation) operation by using a remote controller only in a NAVI mode and to validate only remote controller operations except NAVI in the other modes. SOLUTION: When a NAVI unit 15 is selected as an operating unit, a remote controller signal is transmitted to a remote controller signal line RCL as it is by a microcomputer 22 (1). In addition, when a source unit (TV tuner 16) except the NAVI unit is selected, the remote controller signal is discriminated whether it is for the NAVI unit or for the TV tuner, transmission of the remote controller signal for the NAVI unit is prohibited and only the remote controller signal for the TV tuner is transmitted to the remote controller signal line RCL (2). |
