If anyone is interested, the latest version of the Baltic map can be found at: http://www.smartavionics.com/OSM/baltic.zip (37M gmapsupp.img) http://www.smartavionics.com/OSM/OSM-Baltic.exe (35M mapsource installer) I think it's looking pretty good now but any suggestions as to how it could be improved are welcome. If Markus and his pals put more marine widgets into the OSM database it could be quite a useful thing. Mark
