Abstract: A signal processing section 11 decodes an in-vehicle device signal S3 supplied to signal input terminals 141 to 14n and generates a decoded signal S2. An output terminal 13 is connected with a terminal device 30 and receives the decoded signal S2 generated by the signal processing section 11.

Abstract: A display output terminal is connected to a genuine vehicle on-board display unit. A first image input terminal is connected to a non-genuine image output equipment. Also, a second image input terminal is connected to a genuine vehicle on-board image output equipment. A circuit portion delivers at lease one of a signal S1 fed to the first image input terminal, and a signal S2 fed to the second image input terminal, from the display output terminal.
