A very interesting discussion concerning how these work in Basecamp vs how they work with the Garmin Montanan GPSr can be found on the ADV forum, New Garmin Montana thread, starting on or about page 454 (or post #6796), through the current end of the thread.
Seems to be quite a few differing opinions, and many users have conducted their own experiments and shared results, yet a concise and accurate answer seems to evade us.
I am asking the question here, as we are all discussing route behavior after they are transferred to our Montana GPSr from BaseCamp, as they do not appear to follow the same rules as BaseCamp, and many users are very confused as to the correct methods to create Routes in BaseCamp for their Montana GPSr so they will behave the same on both platforms...
Can we get some official word from Garmin regarding this subject matter, please?
