Correct me if I'm wrong, but Garmin Basecamp does not do route optimization at all. You can't use it to plan routes for 5 delivery vehicles and throw in some business rules like capacity, orders size, time windows, driver's shifts etc.

-create a bunch of waypoints

-select them, create route from selected waypoints

-then right click your route, Optimize Route

You can optimize based on car or truck presets (yeah you can't truck everywhere), shortest/fastest, and export GPX. MMS it to drivers etc. The rest are some bells and whistles.

Thanks for clarifying - yes this looks like single-vehicle TSP without any business rules/side constraints. Not usable for many vehicles either.

Sure, but r24 ignores road restrictions and outputs spreadsheets (lol) instead of proper GPX.

Both sounds like proper features which are not covered yet, thanks for your input!

I already have support for >1 vehicle profiles that uses more than 1 distance/duration matrix for different vehicle types.

This is a wider subject however, that includes road closures and time-dependent access. Also truck routing attributes have questionable quality in default OSM, therefor we do not specifically advertise truck routing for now.

I'll definitely consider an option to have GPX export when will be implementing dispatching to drivers in the future.

However it is always better to dispatch to your own mobile app and call external navigation for point-to-point route, this is a more standard use case rather than opening a multi-stop route directly in navigation app.
