I agree, it also helps when you are like me and run a car gps, it keeps it rather dry with no protection when a pop up shower hits. I put a ziploc over it when I have to have it in the rain.I think the big advantages of a dash mount is that it increases the distance between me and the GPS making it quicker for my ageing eyes to focus on it, the other thing is it places it closer to the line of sight during riding so it makes it less distracting when checking the map.
