You need to go back to routes in Basecamp and choose the "Activity" appropriate to the route. If you want to route on road choose that kind of activity. If you think you might want to edit the route in the Montana, choose "Direct" otherwise you can't edit (insert via points, etc) the route at all in the gps. All the other activity types result in routes which can't be altered in the gps. And you should give up on using Mapsource. It does look easier, but it has none of the advanced capabilities needed if you want to get the best out of the unit. Especially when it comes to map loading to the Montana (or 62/78/Oregon/Dakota), Mapsource is antiquated and better used on 60/76 and older gps. Use MapInstall.
