 The user may press the LEFT key to switch the inputs of

interface.

 The RIGHT arrow key can be used to pop up the

multimedia control icons, the user pressed the down

arrow key to execute the icon.

 The user may also use extra keypad to switch the inputs,

in this case, the white wire of the 6P wire between CAN

box and interface should be cut off.[suggested.]
