OK, firstly thanks for your advice and also cooneyr for your's as well. Both steered me towards what I think is a solution for loading the DB routes on my Garmin Montana 650T.
One has to start by defining a suitable 'Profile'. I created a new Profile for the DB that is based on the 'Classic' Profile in the device. You could probably use the Classic Profile and set that up, but I elected to make a new Profile specifically for the DB, or any other offroad type trips.
Then, for that particular Profile, you 'Setup' the device for what is called 'offroad' on other Garmins. The Montana achieves this 'offroad' status another way as follows: "Main Menu -> Setup -> Routing" leads you to 3 sub-menu settings: Activity, Lock-on-Road, Route Transitions. Set 1. Activity => '
Direct Routing". Set 2. Lock-on-Road => "
No". Set 3. Route Transitions => '
Auto'.
That solved my previous problem and the Montana now loads an entire route (e.g. Main A). Now comes a new problem: I can load and do 'Where To' on all four of the 250 point routes but the Montana can only open two of the routes: 'Main A' and 'Main B+Clnge'. The other two routes won't open in the Montana for some reason. However, I think I found a way round this. Namely, in BaseCamp I can convert 'Main A+Chlnge' that is in the Garmin, from a Route to a Track. Then when I do 'Where To' and select Tracks, it displays the entire 'MainA+Chlnge' as a Track which I appear to be able to use the same way as if it was a Route. Any foreseeable issues in doing it this way?
I have documented all the Setup settings for my new DB1k 'Profile' referred to above, and will attempt to attach it to this message. It may be useful to anyone else with a Montana 650. Or, if anyone has better suggestions for settings, I'm always looking for ways to improve things. If the attachment fails to work, I am happy to email it to anyone interested.
Again, thanks for the useful pointers. Much appreciated.
