Installation

Check the wiki for details how to upgrade.
Warning: Since release 1.8.0, some applications has been moved to the SD card as we ran out of flash space.

MicroSD card files

For certain functionality, like external apps, the world map, GPS simulator, and others you need to uncompress (using 7-zip) the files from mayhem_vX.Y.Z_COPY_TO_SDCARD.zip to a FAT32 formatted MicroSD card.
