Swap the SD Card with the one already installed in the MAP-Slot.

Close the display by pressing the OPEN-Button again.

If the car accepts the SD Card it will now be permanently paired to the MMCS and no longer work with any other car or show up on a computer.

If the firmware on the SD Card is newer than the version already installed the Unit will ask you if you want to update. Press the Update-Button on the screen to proceed.

If you were already on the newest firmware version, the car will normally at most run a short update sequence after you restart the car.

Do not turn off the ignition while the update is running!
