1. A vehicle-mounted equipment comprising:
- command generating means for generating commands corresponding to an input signal;
receiving means for receiving commands transmitted from an information unit;
data generating means for generating display data by interpreting a command when the command is output from said command generating means or when the command is received by said receiving means;
display means for, when the command is output from said command generating means, displaying a screen, based on the display data generated by said data generating means, wherein said data generating means generates display data including layout information of the screen; and
transmitting means for, when the command is received by said receiving means, transmitting the display data generated by said data generating means to the information unit, wherein the layout information produces a layout of the display data, including the layout of at least a map and a command interface, on a display means of the information unit that is substantially identical to a layout of the display data on said display means of said vehicle-mounted equipment.
