Software updating system, electronic devices, and software updating method

A software updating system having a first electronic device and a second electronic device connected via a communication interface, wherein

• the communication interface connects the first electronic device and the second electronic device as well as the second electronic device and a displaying device,
• the first electronic device includes an update data acquiring portion that acquires update data for updating software of the second electronic device and an update data transmitting portion that transmits the acquired update data through an audio transmission line of the communication interface to the second electronic device,
• the second electronic device includes a software updating portion that updates the software of the second electronic device with the update data transmitted from the first electronic device,
• the first electronic device includes an identification information storage portion that stores identification information and software version information of the second electronic device, and if the update data includes identification information and software version information of the second electronic device and the software version information is newer than version information stored in the identification information storage portion, the first electronic device transmits a selection screen signal for allowing a user to select whether the software of the second electronic device is updated through a video transmission line of the communication interface to the displaying device, and if the user selects and instructs update of the software on a selection screen displayed on the displaying device, the update data transmitting portion transmits the update data through the audio transmission line to the second electronic device.
