I ran into the same problem. I fixed it by editing the application.skin file. Find the textline with laneHighColor in it. By default it uses the value "_c.sygicGreen" which is defined in the top part of this skin file. I tried updating the value of the sygicGreen declaration, but this had no impact at all (I do not know why though). So I simply changed the value of laneHighColors to "_c.bgrMainCapion" which is kind of light blue. This seems to work for me. You could choose to change the value to "_c.sygicRed" to show red arrows. Hope this helps. Bas
