Another potential cuesheet issue is if your lights are aimed low, you can't see the street sign name if it is up high on a pole. The GPS popup is just so incredible at night. I change the warning from 100m to 150 meters. I also put a field, "Distance to Next" on my standard screen. If I am going along, I can just look down and see how far to the next turn. This does not always work but I would say that one field has saved me more bonus miles than anything. OTOH, GPS can get confused and the cuesheet is my tiebreaker.
