First of all, this topic won't contain a download but instructions how to update the SD card to with the latest maps.
Step 1: Get a SD card (16GB), format it to FAT32 with 64kb cluster size.
Step 2: Get the base contents for the maps. I haven't narrowed down which files you need exactly, but with these files it works.
