Hello, There is a bug in the way mkgmap uses addr: tags to generate address info for POIs. Specifically, if addr:street is not set, then mkgmap will ignore addr:housename, even if it is set. However, if addr:street is not set but addr:housenumber is set, mkgmap will process addr:housenumber. 1) Example of bug name:Frankie's addr:housename=Cherry Cottage addr:city=London mkgmap processes this to Frankie's London 2) Example where things work as expected name:Frankie's addr:housenumber=Cherry Cottage addr:city=London mkgmap processes this to Frankie's Cherry Cottage London A workaround to this bug is to use the following additional style rule in the points file: addr:housename=* & addr:housenumber!=* & addr:street!=* {set addr:housenumber= '${addr:housename}'} But obviously fixing the bug would be nicer. -- Charlie PS I'm using mkgmap r1907
