I went from a rider2 to a rider 450. The old system gave a perfect image of the curving of the road. It was like radar. When riding in the woods with no clear view around the corner you knew exactly what to expect (the cornering of the road of coarse) . With the 450 a straight line may even have some nasty curves in the road. Is was perfect on the old system. Why did they change it and can i go back to the old graphics?
