In-vehicle device to connect to information terminal and in-vehicle system

An in-vehicle system comprising:

• an information terminal;
• and
• an in-vehicle device, wherein
• the in-vehicle device includes:
• a communication interface connectable to the information terminal;
• a display that, when the information terminal connects to the communication interface, displays an image based on an image signal received by the communication interface from the information terminal;
• and
• an operation interface that accepts an operation on the image displayed by the display,
• the communication interface transmits an operation signal responsive to the operation accepted by the operation interface to the information terminal, and then receives an image signal as a result of processing by the information terminal in accordance with the operation signal from the information terminal, and
• when the communication interface and the information terminal are connected, at least one of the display and the information terminal displays a connection notification.

An in-vehicle system comprising:

• an information terminal capable of executing a first application and a second application that are different from each other;
• and
• an in-vehicle device, wherein
• the in-vehicle device includes:
• a communication interface connectable to the information terminal;
• a display that, when the information terminal connects to the communication interface, displays an image based on an image signal received by the communication interface from the information terminal and resulting from processing of the first application by the information terminal;
• and
• an operation interface that accepts an operation on the image displayed by the display,
• the communication interface transmits an operation signal responsive to the operation accepted by the operation interface to the information terminal, and then receives an image signal resulting from processing of the first application by the information terminal in accordance with the operation signal from the information terminal, and
• the display does not display an image based on an image signal resulting from processing of the second application by the information terminal.
