Hi Frans,

I had read the thread. Thats why I put the map in a subfolder inside its local folder
$HOME/.local/share/osmscout.fransschreuder/Maps/stuttgart/*.dat
too but that didnt work either.

I had problems to add media files to my Aquaris by adding the to my sd card using MTP so maybe thats
the case here too.

Thanks for your quick response and this great app!

Simeon
