A basic question from a newbie when using Mapsource. I'm attempting to plan a route from Mexico to Panama that uses dirt roads a majority of the way. Problem is I can't zoom out more than 3KM before losing my dirt tracks that are displayed on the map. Is there a way to maintain the dirt road visisbility on the map whilst viewing from a farther out ie. 10-20KM at least? If not in Mapsource will Basecamp allow these modifications? The map I've working with is: http://www.cenrut.org/adw/over.htm If there's a better map by all means let me know. Thank you.
