To interact with the menu we use a customized device (in fact a small computer mouse) that is attached to the steering wheel. It is placed behind the wheel as we want to reduce the haptic distraction as much as we can. The scrolling wheel of the mouse lets the user select items within the menu. By pressing the lower button of the two-button mouse the user can select items (or decent in the menu hierarchy) and by pressing the upper button the user can go up in the menu hierarchy.
