An in-vehicle display apparatus includes (i) an operation device having an operation knob, and (ii) a display control device having a display section. The operation device has a drive section which gives force to the operation knob. When the display section displays a display window to enable a scroll display in which several selection buttons are circulated, the display control device acquires a reactive force map. The map specifies that a vibration is applied to the operation knob when the cursor is located on the selection button at the tail end of the series of the selection buttons in the display window. The display control device then instructs the drive section to apply the vibration to the operation knob based on the acquired reactive force map.
