i have seen already more then ones that direction arrows in the gps are pointing the wrong direction and that is sometimes very confusing, seen this on different places on the map. A second thing that i have found is the fact that in the tunnels (in my case in Brussels) are very "jittery".Did not found (for the moment) other "errors"
Thx for the map and the hard work that goes in it!.

Have you got screenshots of those arrows pointing in the wrong direction on the GPS?
