Hi, since the mkgmap website invites to ask any question: I am currently trying to find the reason why my Garmin does not accept maps generated with mkgmap anymore. I am not too familiar and too deep into mkgmap details. I'm using an etrex 30 (and used an older etrex before), and I am using a self written script to generate maps from openstreetmap with the mkgmap tool chain. I used that script for years and plenty of trips, and it always worked, but now the garmin simply does not offer that maps in the map selection menu anymore. What my script does is 1. Get http://download.geofabrik.de/europe/france/reunion-latest.osm.pbf store as Reunion.pbf 2. [ combine several pbf files with osmosis if needed, but not in this case , problem occurs in both cases with and without osmosis] 3. splitter --mapid=63241001 --output-dir=/tmp/d20170604-30580-1rnxv7g --geonames-file=/opt/Geo/data/cities15000.txt --write-kml=/tmp/d20170604-30580-1rnxv7g/splitter.kml Reunion.pbf 4. mkgmap --gmapsupp --index --x-split-name-index --route --precomp-sea=/opt/Geo/data/sea.zip --generate-sea=multipolygon --add-pois-to-areas --add-pois-to-lines --location-autofill=is_in,nearest --housenumbers --output-dir=/tmp/d20170604-30580-1rnxv7g --mapname=Reunion --description=Karte Reunion 04.06.2017 --country-name=Testland --country-abbr=TLD --region-name=Testregion --region-abbr=TRG --area-name=Testarea --series-name=Testseries --drive-on=right --latin1 --read-config=/tmp/d20170604-30580-1rnxv7g/template.args --family-name=HBOX 5. copy the resulting /tmp/d20170604-30580-1rnxv7g/gmapsupp.img as reunion.img in the Garmin folder of the etrex 30 This worked for years, and since I am never issuing the commands manually, but always with my script, I believe that the commands have always been the same. But now, the etrex (same firmware since last trip, where it worked) does not recognize the map at all and does not offer it for selection. Can anyone hint me what I am doing wrong? regards Hadmut
