Hithere If I got it right you can use resolution in style-file and this is directly used as a garmin-map-level. OR I can use level in style-file and this is transferred via --levels="..." to agarmin-map-level. Is there a reason for having two ways of telling mkgmap on which garmin-map-level a object should be displayed? Maybe in help-file it should be written a little bit clearer that --levels="..." is only needed if level is used in style-file. Like: --levels=levels code Change the way that the levels on the map correspond to the zoom levels in the device. See customisation help. The default is: "0=24, 1=22, 2=20, 3=18, 4=16, 5=15", although each style can have its own default. Only needed if level is used in style instead of resolution. Henning
