Specifically, as shown in the flowchart of FIG. 14, the control unit 100 first determines whether or not it is in the two-screen display mode state (step S17).
If it is determined in step S17 that the state is the two-screen display mode state (step S17: YES), the control unit 100 next displays the TV display surface 14T and the map display surface 14M displayed on the touch panel 32. It is determined whether the boundary portion 14B or the display panel center portion 14C has been pressed for a long time (step S18).

When it is determined in step S18 that the boundary portion 14B or the display panel center portion 14C of the two display areas has been pressed for a long time (step S18: YES), the control unit 100 displays the TV and map display positions and heights. Display parameters such as width and width are acquired (step S19). Based on these parameters, the display parameter value for TV display is set as the display parameter for map display (step S20), and the display parameter value for map display is set to TV. The display parameters are processed in the order of setting (step S21).
And the control part 100 reversely displays the TV display surface 14T and the map display surface 14M.
When it is determined in step S17 that the screen is not in the two-screen display mode, that is, the screen is in the single-screen display mode (step S17: NO), the control unit 100 ends the process.

If it is determined in step S18 that the boundary portion 14B or the display panel center portion 14C of the two display areas has not been pressed for a long time (step S18: NO), the processing of the control unit 100 is performed before step S17. Return to the state.
When the control unit 100 performs the processing of steps S17 to S21, the user can invert the arrangement of the TV display surface 14T and the map display surface 14M according to preference by an easy operation.
