When I mountain bike, I always carry a map, but I put it in my pocket or camelbak. I pull off the trail, pull out the map and try to figure where I am. I'm not that good at navigation. (The map never has one of those "you are here" arrows like the maps in the mall!! ).

When road riding (like on centuries), I have NEVER looked at the map. I just follow the crowd and the arrows on the road.

That's just me. I don't need a bag with a map window. But I have seen others using them. It seems to work for them.
