Hi Gerd, could it be, that labels contain all characters including "ß" while index contain only upper-case and expanded versions? This would make searching easier, GPS would have to convert input name using SRT when searching but can display proper name in results. Interesting is, that SRT subfile can be added to a tile and to index. I don't like idea of 2 different sorts for lower- and upper-case. There are 2 different cp1252 in Garmin maps, but as far as i know the second version (not compatible with some old devices) expands "ae" and some underscores/dashes. If you'd like to look at some Garmin maps, there are demo version still available for download: http://static.garmin.com/shared/de/custom/topod2012/testversion/TopoD2012pro... http://static.garmin.com/shared/de/custom/topod2012/testversion/GarminTransA... http://www.garmin-download.de/web/tuerkei/gmapsupp.img -- Best regards, Andrzej
