The last selected compartment is marked with a red character.

Function sequence for loading data storage device
Pressing the load button on the audio equipment causes the Audio/COMAND display (A40/8) to show "Cartridge menu" and the last selected slot in the changer.
Using the Audio/COMAND control panel the required slot can be selected by turning or pressing to the left or right, and confirmed by vertically pressing the Audio/COMAND control panel.
The telephone keypad (1 to 6) on the audio equipment can also be used to directly select the desired slot.
Do not insert a data storage device until prompted on the Audio/ COMAND display by a message, e.g. "Please insert disk 2". Once the data storage device is inserted, a message is shown in the Audio/COMAND display, e.g. "Disk 2 being loaded...".
The loading process can vary depending on the type of data storage device involved.
Once the data storage device is loaded, the display changes back to the "Cartridge menu". If a data storage device is not inserted, the display also changes after t = 20 s back to "Cartridge menu". A loaded data storage device is shown in the "Cartridge menu".
The "Fill up empty spaces" menu enables several data storage devices to be loaded one after the other. Do not insert a data storage device until prompted on the Audio/COMAND display by a message, e.g. "Please insert disk 3". The "audio equipment" then starts to load the empty DVD slots.
The data exchange between the "audio equipment" and the Audio/ COMAND display and the Audio/COMAND control panel takes place through the telematics CAN (CAN A). Video signals are sent over a low voltage differential signaling (LVDS) line to the Audio/ COMAND display.

Function sequence for ejecting data storage device
Pressing the load button on the audio equipment causes the Audio/COMAND display to show "Cartridge menu" and the last selected DVD slot in the changer.
Using the Audio/COMAND control panel the required slot can be selected by turning or pressing to the left or right, and confirmed by vertically pressing the Audio/COMAND control panel.
The telephone keypad (1 to 6) on the audio equipment can also be used to directly select the desired slot.
While the data storage device is ejected, a message appears in the Audio/COMAND display, e.g. "Disk 2 being ejected...". As soon as the data storage device appears in the drive slot, a message is shown, e.g. "Please remove disk 2".
Once the data storage device has been removed, the display changes back to the "Cartridge menu". If the data storage device is not removed, it is drawn in again and loaded.
The "Eject all" menu enables all the data storage devices to be removed one after the other.
As soon as the data storage device appears in the drive slot, a message appears, e.g. "Please remove Disk 3". Once the data storage device is removed from the drive slot, the next one is removed until the cartridge is empty.
An ejected data storage device is shown on the "Cartridge menu" as an empty slot.
The ejection procedure can be stopped at any time by pressing the load button on the "audio equipment" or the "Back" button (A40/9s2) of the Audio/COMAND control panel.
