The screen of the COMAND display (A40/8) can be adapted to the needs of the individual user using the cockpit switch group (S6/2).

Component Identification:

Shortcut buttons
Buttons which permit direct access to the MMI functions are provided on the front central operating unit to allow main functions to be accessed quickly.
The disc/radio quick select button is double assigned. If this button is pressed once, then the disc application (e.g. Audio CD/DVD) which was last active starts. If this button is pressed once more then the radio function is activated.

Each time the button is pressed again it switches between these applications The corresponding applications can also be activated directly there using the telephone/navigation quick select button.

Rotary pushbutton
The rotary pushbutton is used to move the cursor on the screen and to select and activate functions.

Component Identification:

Status line
The contents of the status line cannot be selected or changed. All displays (e.g. mute, provider name or letter symbol for new SMS messages) relate to the current system status.

Main menu row
The main menu line is a menu line in which equipment-specific and vehicle-specific functions can be selected. The main menu line is actuated via the front central operating unit.

The main menu line contains the following 5 application groups:
^ "Navi" Menu item for navigation settings
^ "Audio" Menu item for audio component settings (radio, audio CD/ DVD, MP3)
^ "Tel" Menu item for communication component settings (telephone, SMS, address book)
^ "Video" Menu item for video component settings (TV, video DVD)
^ "Vehicle" Menu item for configuring vehicle components which can be operated via COMAND display

Application groups which are not available to the user are grayed out and cannot be selected.

Main menu selection range
The graphical display in the main menu selection range varies corresponding to the requirements of the selected application. The information contents of the active application are displayed in the main menu selection range. With video applications TV and DVD as well as in the navigation map display the main menu selection range can fill the entire screen in full picture mode.

Submenu line
In the submenu line the options and functions of the active application of the main menu line can be operated and their submenus can be selected.

Air conditioning functions row
The air conditioning functions are shown by symbols. Apart from a few exceptions and independent of the active application, the air conditioning functions are always visible (exception are full picture display of video signals, navigation map displays as well as faded in spellers).

Component Identification:

Cursor
The cursor indicates the function or option which is currently selected. It is highlighted by a light-colored background and moved using the rotary pushbutton of the front central operating unit. Exceptions are sliders which are orange.

Component Identification:

Active area
The active screen area is the area in which the cursor is located. It is the area which can be influenced directly. Options and functions can be only be activated in this area.
The contents of the active area are highlighted in color (lighter). All non-active areas are dimmed. These areas can be activated by means of the front central operating unit.

Graphic feedback and user interface
If a function or option is activated using the front central operating unit, the system always reacts by displaying graphic feedback. The following sections describe the most important graphic elements used for selecting and configuring functions:
^ Menus
^ Spellers
^ Sliders
^ Checkboxes

Menus
The menus are displayed in horizontal and vertical lists. The menu items can be selected by rotating the rotary pushbutton counterclockwise/clockwise or pushing it to the left/right. If a menu item is to be activated (to select an option or a submenu), the rotary pushbutton must be pressed down vertically. Should another screen area be selected, then the turn/push control must be pushed forward or backward.

Menu displays as horizontal list, shown on model 221 up to 31.8.06

Menu displays as vertical list, shown on model 221 up to 31.8.06

The width of the vertical list is determined by its longest item.

Opening and closing submenus
Submenus can be opened in all screen areas (with the exception of the status line). The cursor is moved in the menu by rotating or pushing the rotary pushbutton. Submenus are opened by pressing the rotary pushbutton.

Submenus can be closed in the following ways:
^ by activating an option or function
^ by pushing the rotary pushbutton horizontally
^ by pushing the "back" button on the front central operating unit
- pressing once briefly leads to activation of the preceding menu
- Pressing for a longer period (more than 3 s) leads to the closure of all submenus; the basic screen of the application is displayed

Example: Setting time for displaying submenus, shown on model 221 up to 31.8.06

Displaying submenus
A submenu is opened by activating a list option. In many cases, various steps of submenus are shown next to each other.

Example
The example shows how the time is set. The following menus and options must be activated:
^ "Vehicle"
^ "System settings"
^ "Time"
^ "Clock"

Displaying paths
If a submenu is opened, the previously active area (screen area or menu) remains open. It is, however, dimmed (i.e. inactive). All areas, except for the active area, are dimmed.
The entire path thus remains on screen and can be traced back if necessary.

Spellers
There are 2 spellers, each with a different function:
^ Edit speller
^ Matching speller

Shown on model 221 up to 31.8.06

Edit speller
An edit speller is provided for functions in which texts, numbers and characters have to be entered. The elements are selected one at a time by rotating the rotary pushbutton or pushing it to the left or right. An element is adopted in the text being entered by pressing the rotary pushbutton down vertically.

Shown on model 221 up to 31.8.06

Matching speller
With the matching speller, the entered characters are compared with list entries and the nearest possible entry is displayed. This matching speller also allows the user to search for entries without the precise target or result needing to be known. The elements are selected individually using the turn/push control until the desired list entry appears. The entry can then be activated by pressing the rotary pushbutton down vertically.

Shown on model 221 up to 31.8.06
Slider for adjusting the treble in the "Audio" menu
Sliders are used if the intensity of the setting is depicted graphically.

Example
The example shows a slider for adjusting the sound property "treble". Sliders can be moved by pushing or rotating the rotary pushbutton in the required direction. The rotary pushbutton is locked when the top or bottom of the menu is reached, and cannot b rotated further in this direction. A value is adopted and the slider is closed by pressing the rotary pushbutton down vertically or pushing it to the left or right.
