Old Russan saying at school of engineering: Better is the enemy of Good! Do you know if Mapsource will NOT comunicate with any new units to transfer Tracks & Waypoints or .gpx file if that is how it is done? None on these features are of any use to me and I question Data Management but until I actually learn it in Base Camp, I will reserve judgement. I think I need to buy a Montana just to follow the conversation. I neeed some rational for that much money for something I can't see I need.
