Hi, this list is said to be suitable for *any* questions about mkgmap. I'm trying to create my own img files for a garmin eTrex (instead of downloading from the tile server). For some reason it does not work the way I expect, and even by reading all web pages I could find about usage of mkgmap, I did not find the problem: wget -O muenchen.osm "http://api.openstreetmap.org/api/0.6/map?bbox=11.54,48.14,11.543,48.145" java -jar mkgmap-r2232/mkgmap.jar muenchen.osm produces an img-file of just 9216 bytes, there must be something wrong. And java -jar mkgmap-r2232/mkgmap.jar --index --gmapsupp muenchen.osm even aborts: SEVERE (LocationHook): muenchen.osm: Disable LocationHook because boundary directory does not exist. Dir: bounds Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: -1 at java.util.ArrayList.elementData(ArrayList.java:338) at java.util.ArrayList.get(ArrayList.java:351) ... Is there anywhere a step-by-step-introduction? I did not find any hint about what I am doing wrong and what options are really required to generate img files. regards Hadmut
