Hi When using this command line: java -Xmx512M -ea -jar mkgmap.jar --transparent --style-file="c:\dwgs\Programs\GPS All\Garmin Profile" --family-id=42 M000002.TYP 63272002.gz it creates a 63272002.img using my customized styles & when uploaded appears as I would expect. But when I use the same file to be included in the gmapsupp file in this command the 63272002.img displays as if it was created using the built in style of mkgmap: java -Xmx512M -ea -jar mkgmap.jar --remove-short-arcs --gmapsupp "Contours.img" "63272002.img" --generate-sea:polygons --transparent --style-file="c:\dwgs\Programs\GPS All\Garmin Profile" --family-id=42 M000002.TYP MyTown.osm move "C:\dwgs\Programs\GPS All\mkgmap\gmapsupp.img" "L:\Garmin" Any ideas as to why this is? Cheers Dave F.
