Claude,

There is really only one way to find out. Order it and try it out. You got 27 days to return it if you don't like it. Use it for GPS navigation under the conditions you are concerned about and see if it's visibility is sufficient to your needs. I don't want to talk you out of buying a very good ppc. Try everything before the 27 day period and who knows you might just find it suitable to your needs.
