Hi all, I am looking at the problem described by Enrico: http://gis.19327.n5.nabble.com/Different-rendering-tp5803738.html One of the reasons for the problem is that mkgmap treats "roads" different to other lines. Another problem is that it is not clearly documented how you can change a way to a road. If I got that right, Garmin will not route over lines with non-routable types. A routable type is between 0x01 and 0x13 or one of: 0x1a, 0x1b, 0x16, so all other are non-routable. The problem: We calculate the road network for all ways with a road_class/road_speed atttribute and a type that is not extended ( < 0x10000), no matter if the type is routable. Is this intended? Gerd
