Destination Waypoint Missing in Zumo XT
-
@Con-Hennekens when I recreated the route from scratch. I started with my home address being the start and my next-door neighbor being the finish. It recalculated in the XT correctly. I then modified the MRA route to make my home address both the start and the finish. Again, it recalculated in the XT correctly.
My habit in round trip routes is to use my home address for both the start and the finish. I've never previously had a problem in MRA. I've also never had a problem in Basecamp or inRoute. Maybe there is a better best practice for this, but again, I've never had a previous issue with this practice in any environment.
I'm attributing this to a one-off, since I couldn't recreate it. If it happens again, I'd appreciate you looking at the GPX file for diagnosis. Thanks.
@John-S-Parry, I agree, if it is not reproducable, it is hard to discover any problem.
I am just an enthusiastic MRA user, and hope you will be one too!

@Con-Hennekens that could very well be the case. I don't know enough about the internals of a GPX file to say one way or another.
What makes me suspicious is the following:
-
Before I made a lot of last-minute changes to the MRA route, as far as I remember, it looked fine on the XT side.
-
After the series of MRA changes, I transferred to the XT for my ride, and I got lazy and didn't do my normal detailed XT route verification. I didn't know anything was wrong until I got towards the end of the ride.
-
After returning home and investigating, no matter what changes I made to the route on MRA, a correct transfer to the XT didn't work. The XT always created the end point wherever the last shaping point was located.
-
I Finally deciding to start from a clean slate and recreate the route from scratch. Everything then worked correctly. The MRA route recalculated in the XT as created.
This all tells me that the MRA created GPX file is the culprit. The XT only works with what it's given. Garbage in, garbage out. Again, I'm not trying to find fault here -- just a logical answer. In Google Maps, I'll sometimes create a route and then proceed to make a bunch of stopping point changes. At some point, the calculated route is all messed up and the resulting map is a mess. At that point, there is no other choice but to start over. I believe a similar thing happened here.
My lesson is to assume nothing and always check the re-calculated route on the XT. A lesson that's easy to forget when things generally go well. I've had rare, strange results when creating routes in Garmin Basecamp and transferring to the XT. None of this is usual, but the minute you let your guard down, surprises can happen.
@John-S-Parry Unfortunately with an XT "garbage in, garbage out" is not the appropriate phrase. The XT can screw up a perfectly good route / gpx.
I would pretty much bet on the issue being with the XT, there are multiple known issues with the XT.
When navigating with the XT do you have route recalculate enabled?
If recalculate is on & there has been a slight deviation during the trip, it is possible the XT may have entered into the RUT / CEP loop where the XT shows a blue spinning circle in the route info panel.
With this issue the XT gets confused & half (nav instructions) is working on the correct data & current position, the other half (route info) is out of sync & working on data at least one waypoint behind.
It would not surprise me if due to the out of sync calculations occuring the XT suddenly decided it had reached the end of the route.BlackView BV7100, Android 12, Offline mode with Offline Maps

Again, I'm just suspicious given the total circumstances. Clearly, when I recreated the route from scratch this morning, it wasn't "identical" in every sense to the original. It covers the exact same path (roads and turns), but the location of specific shaping points were obviously a little off from the original. These are manual placements and impossible to recreate exactly to the same GPS coordinates. But otherwise, no differences that would materially change the route.
With the XT, re-calculation is automatic when the route is initially imported into the XT Trip Planner. And the route recalculates automatically right before the route is executed. This is controlled by the XT and can't be changed. To my knowledge, the only route recalculation you can manipulate in Settings is Off-Route. You have the option of Automatic, Off or Prompted. I never went off-route during this trip. I have the setting at Prompted, and never issued a recalculate during this trip.
Again, I couldn't recreate the scenario when I recreated the trip from scratch. Maybe if I did a large number of modifications, I could trigger some strange behavior. But I can't spend any more time on it unless it happens again. Hopefully, it won't.

One more thing....
I went back to look at the version of the route that prematurely finished as previously described. I see a red dot (circled in blue):
I don't remember seeing this earlier, but maybe I didn't have the right zoom level. I did a search on this but came up empty -- that's why I'm asking here.
BTW, this shaping point (#13) location was a mistake in the route that I didn't catch. I meant it to be on the highway directly above. Here is the route with public viewing:

@John-S-Parry your 100% correct with your descriptions of when an XT calculates importing & starting a route
Where things can & seem to have gone awry is exactly at point 13 where you have deviated from the planned route.
The XT would have been expecting to come off route 118 & up the small road to point 13.
I am assuming you carried straight on along route 118 which will have made the XT perform a recalculation to either return to point 13 or possibly skip it.
Either way this deviation could very easily have got the XT into one of its confused loops which happen frequently wen recalculation is set to automatic or promptedBlackView BV7100, Android 12, Offline mode with Offline Maps

At the time while riding, I was surprised by the XT deviating me off the 118. I know that area/side road well and knew it would only be a very small deviation to follow and keep the route intact. Out of curiosity, I proceeded to the side road, and when I reached the end point you see on the map, the route completed in the XT. So, there was no deviation or recalculation.
As I mentioned, that point #13 was a mistake. I didn't have my glasses on and thought I was placing a shaping point on the 118.
I'm guessing what happened is that I actually placed an off-road point somewhere between the 118 and that side road, and MRA decided to place the point on the road itself. Maybe it would have run properly on the phone app, but there was something in the GPX that tripped the XT up.I wanted to play with it, so I copied the route to a new name and corrected it, deleting #13 and adding a new #13 on the 118. No matter what I did, the XT would always stop at the last shaping point before real end point. This is all conjecture, but I think the original #13 somehow corrupted things when saving the GPX.
I've since recreated the route from scratch, and all waypoints transfer correctly to the XT. Maybe my hypothesis is way off base, but I can't figure out another explanation.
