As has been discussed, if you want to make sure your route will calculate properly create a Route in BaseCamp that follows the path you want and then create a Track of the Route. Just before sending your Routes/Tracks to the Montana, change your Routes to Direct Routes. Once on the Montana make sure your Routing Activity is set to Automotive or Motorcycle Driving. This will cause the Montana to calculate your Route into an along-road route. Now you can compare it to the Track as mentioned and verify that the Montana calculated the route as you intended. The side benefit of this process is that you can now EDIT this route on the Montana - including reversing the Route.
I've never changed anything to direct routes to get the result wanted. If I let the Montana calculate the route it is never the same as if I just transfer it and make it use what I sent.
