Hi Marko, Yes I already do those tweaks in my Openfietsmap. You can test your route when it is rendered sooner or later on Lamertus' server http://garmin.openstreetmap.nl Every way that is part of a relation with route=bicycle gets a higher road class/speed, so when you choose to set the routing to faster route instead of shortest way, it takes a more scenic bike route. If you use "avoid toll roads" the routing is forced to use those route=bicycle relations.
Has anyone experimented with this kind of tweaks to routing? Would this bypass the limitation that the Garmin Edge 705 seems to ignore cycleways for the middle section of a route?
I dont know the Edge 705, what I do know is that the new Edge Touring now doesn't have a car/pedestrians settings anymore (only mtb/touring bicycle and bicycle mode), and also no options to avoid toll roads. So when users want to use my map this really sucks :( BTW The Edge Touring is a very interesting device because it contains an official Garmin EU cycle map based on OSM!
