Each menu has at least one menu item. Upon selection and activation of the menu item, a next level of a submenu is displayed on the display. Users may operate an operating element to select and activate the menu or menu item. The vehicle multimedia system includes a memory that stores information identifying the menu or menu items. Upon activation of the menu item, the identification information may be stored in the memory. The stored information may be retrieved upon activation of the operating element such as a key, a switch, etc. Upon no selection and/or activation of the menu item for a certain time period, the main menu may be automatically displayed. Upon activation of the operating element, the vehicle multimedia system may reach a specific menu such as a last accessed menu or menu item, a menu or menu item saved by users, etc.
