I build all maps of my web site [1] using the same parameters for mkgmap (apart from name, FID, etc.). Most of them work fine, but those of full USA or single USA states have no POI's when installed on device, with no difference if I use mkgmap generated gmapsupp or MapSource generated. On MapSource/BaseCamp POI search works as expected. I use the following general mkgmap call: java -Xmx2800m -ea -Dlog.config=logging.properties -jar mkgmap.jar --output-dir=./tmp --bounds=bounds.zip --precomp-sea=sea.zip --max-jobs --route --latin1 --code-page=1252 \ --country-name=$PAIS --country-abbr=$ABR --area-name=$MAPA --family-name="OpenStreetMap $MAPA" --family-id=1$FID --product-id=1 --series-name="OSM-$MAPA" \ --overview-mapname=$ABR-1$FID --overview-mapnumber=551${FID}000 --name-tag-list=$NAMETAG --index $RNP --process-destination --process-exits --housenumbers \ --remove-short-arcs=0 --reduce-point-density=4 --reduce-point-density-polygon=8 --polygon-size-limits="24:12, 18:10, 16:0" --add-pois-to-areas --adjust-turn-headings --report-similar-arcs --report-dead-ends=2 --link-pois-to-ways \ --location-autofill=is_in,nearest --drive-on-$DRIVEON --check-roundabouts --check-roundabout-flares --license-file=license_ODbL.txt \ --copyright-message="OpenStreetMap contributors, ODbL. See: http://www.openstreetmap.org/copyright" --style=mio --check-styles -c $pais.args Which becomes as follows for USA with the variables assigned: java -Xmx2800m -ea -Dlog.config=logging.properties -jar mkgmap.jar --output-dir=./tmp --bounds=bounds.zip --precomp-sea=sea.zip --max-jobs --route --latin1 --code-page=1252 --country-name=USA --country-abbr=USA --area-name=USA --family-name="OpenStreetMap USA" --family-id=148 --product-id=1 --series-name="OSM-USA" --overview-mapname=USA-148 --overview-mapnumber=55148000 --name-tag-list=name --index --process-destination --process-exits --housenumbers --remove-short-arcs=0 --reduce-point-density=4 --reduce-point-density-polygon=8 --polygon-size-limits="24:12, 18:10, 16:0" --add-pois-to-areas --adjust-turn-headings --report-similar-arcs --report-dead-ends=2 --link-pois-to-ways --location-autofill=is_in,nearest --drive-on-right --check-roundabouts --check-roundabout-flares --license-file=license_ODbL.txt --copyright-message="OpenStreetMap contributors, ODbL. See: http://www.openstreetmap.org/copyright" --style=mio --check-styles -c usa.args Any idea what can make the difference with USA maps? [1] http://mapas.alternativaslibres.es/download.php
