Thanks quick feedback Dave. I've noticed changing my main route from 2ndary road to HP does not give me the dotted line. It does however changed the road types to others as need be. When I drags the HP (off piste) road type it displays it as a secondary road type not a dotted line.
I'm running i.e. 10 , maybe that will help?
Dreaming of Dakar
Everyone has a max speed, 90% of that max speed is much safer and easier, and if that 90% speed isn't fast enough at Dakar, you enter the snowball. - neduro
