You can create routes in routeconverter. Than convert this route with RouteImporter. RouteImporter will directly place it in Navigator free as a route making it possible to completely use this as a route.
I have installed RouteImporter and imported some files - problem solved!
Now moved to the testing stage.
One problem with pre-recorded routes is the behaviour when a waypoint is missed, due to a road closure or any other reason, the app insists of re-calculating back to the missing waypoint although the next waypoint has been reached.
The Garmin Zumo 390 has the option to ignore or bypass a waypoint - still annoying as you must stop (being on a motorcycle) and physically key in the instruction to "ignore" the "passed" waypoint.
Ideal solution is to ignore the missed waypoint after say a time limit or distance limit of ignoring the redirection to the "missed waypoint".
Thanks for pointing this out to me - I will add my comments to that discussion.
Any idea how to get a suggestion on to the "change request list" for the developers or project members to evaluate and hopefully deliver the enhancement ( I will add this to the other discussion)
