Hello, I installed an 4589 map onto my Etrex 20, and all the Waypoints and routes were somehow deleted. The Waypointsxxx.gpx and other gpxfiles were still still present. As I have seen this problem before after updating firmware, I found that I could get the Etrek to re-read the Waypoint (and Route) gpx files by renaming them. There are more details on this blog post: https://hyperentang.wordpress.com/2018/04/16/lost-waypoints-on-garmin-etrek-... Presumably there is something in the img file which is somehow altering the Waypoint status? Here are the commands that I used: java -Xmx10g -jar ../splitter-r597/splitter.jar ../great-britain-latest.osm.pbf Then I compiled the mapnik.txt from version 4589: java -Xmx13g -jar ../mkgmap-r4589/mkgmap.jar ../mkgmap-r4589/examples/typ-files/mapnik.txt Finally I compiled the img file with java -Xmx12g -jar ../mkgmap-r4589/mkgmap.jar --route --add-pois-to-areas --bounds=../bounds --precomp-sea=../sea/ --index --gmapsupp --remove-ovm-work-files mapnik.typ -c template.arg Did I do something wrong, or is this a known problem? ael
