I know this question has been asked before but I am going to ask it slightly different way. I want to get the Edge 800 but want to know if it can tell if a road is paved or gravel. I ride a lot of country roads and never know if my route is paved or gravel. Sometimes I will take a turn ride down 2km only to find I have to turn back because its a gravel road. If the Edge 800 could tell me a road is gravel when I am plotting out a route that would be amazing. If cannot I think I will opt for the Edge 500 as the mapping at that point will be useless to me.
