I use OSM a lot for planning routes, decide where to pass, and then I set Google Maps and fight with it. But I didn’t find anything satisfying yet for turn by turn. I’m on the the verge of making my itineraries in GPX form.

Googke Maps in my city and region sucks so much for bikes. But I look at its suggestions, ignore them when I know a safer route, and follow them if I didn’t plan a route and need to get from A to B.
