Ok, here are my observations with the index and address search Mapssource with opemmtbmap Germany 28.10.2009: If i give the City in City field and then choose a street out of the "Choose street" window i got always " no element found. But If i give instead the City in German federal Land/Province field and then choose a street out of the "Chosse street" window i got the searched street. Entering the city in both fields breaks the search again. Ok, searching by simply using only the streetfield works. GPS 60csx with opemmtbmap Germany 28.10.2009: if i try to enter a city in the city tab of the address search, i got a "no found"(immediately if i enter the first character.) I have to enter the full city name like Clinton mentioned. But if i have entered city name, streetname, housenumber no address is found.Only then deleting the city helps. The only way to search is to enter a housenumber and a street, then i get a list of similar named streets in different citys(as far if there are), but also the attempt to reduce the search result by entering the city fails as i describe above. Only if i directly choose one out of the search result it will be found. If i transfer the osm map together with an other map which contains also an index, address search dont'work. Together with a Metroguide only the metroguide index works. Together with an other mkgmap map address search don't work for any of the maps.(e.g openmtbmap De + own mkgmap created trailmap) Address search works with multiple tiles out of a mapset (tested with 4 tiles) cheers Gert
