Abstract: An electronic device that can reduce a noise caused by a signal or data being always output. A vehicle-mounted device includes: a player that reads out and outputs data recorded in a CD or a DVD (i.e., a TBCK signal, a TSD0 signal, and a TWS signal); a controller that receives the data (i.e., the TBCK signal, the TSD0 signal, and the TWS signal) output from the player, and executes various controls based on the received data; and an interrupt unit that interrupts transmission of the data recorded in the CD or the DVD to the controller until the CD or the DVD is inserted into the player.
