Hi, I have found a situation where --adjust-turn-headings creates a non useful turn hint. Compile the file: http://files.mkgmap.org.uk/detail/207 with parameters --route and --adjust-turn-headings (maybe also --x-no-mergeroads for easier debugging). Try a route from Frankfurter Straße to Eilper Straße. Mapsource and the GPS give a hint that you have to turn right on the junction of Frankfurter Straße and Eilper Straße although the street is straight. Logging of the RouteNode class gives the hint: Adjusting turn heading from -52.342655 to -99.54512 at junction of (http://www.openstreetmap.org/browse/way/31171248) and (http://www.openstreetmap.org/browse/way/144387754) at http://www.openstreetmap.org/?mlat=51.349647&mlon=7.484266&zoom=17 For me the initial heading -52.34... looks weird. Gerd, do you have any ideas? WanMil
