@skids,
do you know, how big a topomap created map can be for for using with Locus.
I created a map of whole France with 1:25.000. But this is to big for Fat32 because it has 7,8GB. So I splitted it to 3.8GB maps, but they don´t work, I only get some light brown raster.
Small(er) maps (200MB) work fine, I will try up to 2GB.
