Memory card and Aventura
It is very important for the new Aventura to use a suitable memory card! These should correspond to a special specification otherwise they will not be read by the device! Attached is a photo of a 64Gb SD card from another brand that has been successfully tested.


Some files and folders have been renamed, which even leads to the uselessness of the mosaic map on a compatible SD card, see picture-1 above and how it should look right see picture-2. Furthermore, all maps are stored in a folder Maps, this is not necessary, these can be transferred directly to the SD card.

Picture-1: File structure that does not work Picture-2: Functioning file structure which one should choose

Screen protector
Now there will be also a German manufacturer who will offer a foil for the new Aventura! I have listed two providers here once: from Germany
