Hi,Sorry last one was meant to go to you
you should extract the 2020 maps on a 32GB SD card and the content in the root of the SD Card should look like this:
Format the SD card prior copying with FAT32. If you have MMI 3GP, delete folders LIT1/LIT2/LIT3 (they are in the pkgdb folder) prior copying to SD Card, you don´t need them. Otherwise the content won´t fit on the SD Card.
