Unit is a 650. Loaded with City NV, US Topo 24 and Canada Topo 24 (which is nicely routable)

1 - The Garmin tech told me that once a route is made in BC it will NOT reroute/recalculate when uploaded to the unit. Unless you breach the parameters of the unit - ie. number of viapoints or have a different map. It will not assume the settings on your unit. These settings are "set" in BC and attached to the route and will not change when adding the route to the unit. Or when navigating. The only changes occur if the unit recalculates during a trip and you can set it to not do that. This seems born out by my experience but the rep could have got me wrong...?

2 - Can you clarify as I forget now if this works - but - When following a route and needing to get off the route for gas etc. I have stopped navigating and dropped a waypoint at the turn off. Then I route to gas and if needed navigate back to that waypoint, (or follow my auto track) and then start routing again (on my original BC route) and the unit will pick up the route where I left off. This seems pretty simple and easier than stopping and editing a route.

3 - I created a 182km route using BS 4.1.1 using the route tool and then shaping it to my needs. The track conversion info gave me over 1800 points - and the unit handled that route fine. But I might be confusing the issue.
I'm hoping someone with more experience will answer, but glad you found this useful so far.

1. About whether the Montana will recalculate, I've heard mixed information and since you've tried it I believe you. Frankly after all this routing knowledge I've learned (without living with the Montana on the bike much)... I'm going to stick to Tracks when off road so I don't care that much

2. Yes that does sound simpler, I was trying to come up with a solution specific to the person's question but your way sounds simpler. It changes the running stats for the miles you have already traveled though, so technically it is different. YMMV.

3. IF I understand you here, you are using BC to autoroute then having BC "Create a Track" from the Route. Then transfer the Track to the Montana (which can handle 10,000 points in a Track). This is exactly what I plan on using quite a bit, especially for Offroad trips using the Topo 24k maps that can autoroute (in BC) but in the end I will then create a track and use it. ... BTW it's being discussed now in the main Montana thread.
