Hi Minko,
I found out that the routing errors still exist when you have two routable lines on top of each other, one with and one without road speed/class parameters. If the GPS finds an address on such road, routing goes mad. In my style I use type 0x02 for all cycleroutes. I need to use 0x02 because this is one of the few type that are always rendered on top of all other lines.
just to make sure: your style creates two lines for one OSM way, they have different types, but both below 0x3f, and one has road speed/class , the other has not. Which one come first?
If it were possible to skip address search on the last routable line somehow I could make it not routable, but I'm not sure.
For mkgmap, a routable line is one that has a road speed/class and a non-extended type. I am not familiar with the code regarding indexes for address search. I don't know ihow this is related to routing.
Normally multiple routable lines are not often needed, so the removal of those warnings is still ok.
I think when it causes problems, we should try to find a better solution or print a warning. Gerd
