ON-VEHICLE SYSTEM AND KEY ASSIGNMENT METHOD

PROBLEM TO BE SOLVED: To provide an on-vehicle system capable of being easily operated by various remote controllers.SOLUTION: A detection processing part 2 is connected to the remote controller 6 that outputs a different voltage for every key pressed by a user and detects the voltage output from the remote controller 6. A display part 51 displays a list of functions assigned to the key on a function display area. An input part 52 specifies the function by the input operation of the user to the function display area. A processing part 3 assigns a function to a voltage that the detection processing part 2 detects by specification through the input part 52.
