  10. The SD Card has to be a 16GB SDHC card with at least 15.718.400.000 Bytes and 30.700.000 Logic Sectors.
  11. If the SD Card you have is a bit too small, but you have larger one on hand, you can also just flash to the larger one, format the smaller one to exFAT at 512 Bytes per sector and copy all the files over from the larger one. This might lead to some instability, but still works.
  12. Insert the SD Card into your PC.
    13. Step image
  13. Launch WinHex as Administrator.
  14. Right click on winhex.exe and choose Run as Administrator.
  15. In WinHex, choose File > Restore Image.
  16. Choose the MAP_20##A_##.whx file you downloaded in Step 3.
  17. Choose the Physical Storage Volume (SD Card) you want to flash.
  18. Make sure that you are flashing to the correct Physical Volume! Flashing to your hard drive will break your operating system!
  19. Confirm by pressing OK.
  20. This might take a while depending on the speed of the SD card you selected.
    21. Step image Step image Step image
  21. Repeat the previous step with the SYS_EU_###.whx file for the System area.
  22. Close WinHex.
  23. Safely eject the SD Card.
  24. Reconnect the SD Card to your PC and check the files on it.
  25. If the file names are a garbled mess, as shown in the second image, you need to reformat and reflash the SD Card. Closing WinHex, ejecting and reconnecting the SD Card between steps 5 and 6 might help. In some cases it might also help to format the SD Card to NFTS before flashing.

  31. 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.
  32. 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.
  33. Do not turn off the ignition while the update is running!
