After having done so much work building routes in Basecamp or Mapsource, why can't those routes be used without recalculation on our gps units?
I'm speaking specifically about the Montana here - many people are waiting for Garmin to fix this automatic "Route Recalculation" issue before giving up their antique X76 units.
Many people simply won't buy a unit which does not take routes as downloaded and just navigate them, assuming of course that the same maps reside and are enabled on the gps.
Actually, this brings up an idea - maybe the route you download from Basecamp could have settings included which 'enable' the required map, assuming it's on the gps.
