Hi, Sorry for late answer, but i was not able to login there So To get M working on N900, you have to copy a valid geotiff file to MyDocs/MyMaps directory. Only the tif file. The setup is here http://qlandkarte.org/index.php?opti...d=13&Itemid=14 Once you press the rebuild database button, the maps should appear on the list below, if it is not the case, it mean the tif have wrong format. to make some test you can get here a OSM world map exported to geotiff -> http://linuxbox2.free.fr/Bugtest/basemap_wgs84_x.tif To export correct tiff with GT, please look at the picture here http://linuxbox2.free.fr/Bugtest/qlandkarte.JPG Regards, Fabrice
