Version mkgmap-r3649 was committed by gerd on Tue, 27 Oct 2015 sharp-angles-v4.patch with small modifications - remove the code for --adjust-turn-headings which no longer worked - add code to fix sharp angles (enabled by default) Enlarge sharp angles at road junctions so that the time penalty is smaller. In OSM, junctions are often drawn without reflecting the exact angles of the roads, they are more symbolic. We assume that in most cases an angle below 45° doesn't really exist as such and therefor the heading values of the arcs are modified so that the Garmin routing algorithm "sees" a less sharp angle. If needed, the option --ignore-sharp-angles can be used to disable this.
