Ah - now there is a question.overlookh wrote: Thu Jun 12, 2025 9:22 am I wanted to ask you if by chance using preconfigured waypoints instead "via points/shaping points" the route could be more deterministic?
Bye.
Are you sitting comfortably.....Then I'll begin
First of all - The XT2 has started calling these pre-saved points "Waypoints" rather than the rather vague 'Saved' or 'Favourites'. 'Waypoints' is the correct name.
They are stand alone locations which you can display on the map.
From the Zumo 590 onwards, a waypoint could be used as part of a route and it could be set as either a Via Point or a Shaping Point.
In fact the waypoint was not part of the route. There were two entries in the GPX file. The Waypoint which was set at aparticualr location and the shaping or via point that was part of the route. This was set at exactly the same location. So it gave the impression that the Waypoint was actually part of the route.
There was some linkage between them, because as well as adopting the same coordinates as the Waypoint, the route point (via or shaping) would also pinch the Waypoint's name. Which was really very handy - because the XT1 would never move or change the name of a route point that had been used in a route.
That changes with the XT2. The waypoint at first seems to be set as part of the route. But the routing software doesn't treat them as being joined together at the hip. If you use a Waypoint as part of a route - then it creates your via or shaping in exactly the same location. But then the XT2 or the synchronisation process is in the habit of shifting the points slightly. And they leave the waypoint alone. So now, the Via Point (lets assume that the waypoint was set as a Via when the route was created) is in a different location from the original Waypoint.
And that means that the route no longer passes through the Waypoint !!! You can see the waypoint symbol on the map and if you zoom in, the Vai point flag is not in exaclty the same place.
This may not make much difference to the route - they may be close enough - but I use Waypoints to place a location that I know is not going to be altered - at the place where I want to park the bike - not on the main road. The XT2 will probably not get me to that location, although I will be able to see it on the map.
I'd love to get my hands on whatever it is that the development team drink. I'd have not a care in the world.
But I believe that a route made entirely of Via Points will behave in a much more satisfactory way than a route that contains shaping points. I think that is the way that @Oop North John uses his XT2. For me and my pillion, that method - although pretty reliable - doesn't work. We like the trip planner to show the distance and time to the next stop / via. Other considerations come into play when you start getting older - and we started that journey a while ago now !!
