Oh, that would seem to be applicable for a scenario where you have a grid of highway=residential, and among them a main road (say, highway=tertiary) that is going like zig-zag within the grid. Could it be that Garmin is not issuing a turn instruction in this case, when the main road consists of a single object (with a sharp turn in it)? AFAIR, there was another option for implementing support for through_route relations, in a case where a main road goes zig-zag through a village. Is it still present in the code base? Maybe it makes this case of --adjust-turn-headings redundant? Marko
