Tread route mystery

[bombermonk]

I have a Garmin Tread which is not synced to explore.

When I want to ride a route that I made in basecamp it takes a long time to open the route and show it on the map. Once it does show it shows a route that is 35000km long, and a bunch of waypoint flags.
Some other routes just show a ton of the waypoint flags but the route is correct like in basecamp. The amount of waypoints seems to make everything really slow, though.

Anyone know what is going on?

Please share the route. I will look into it

I just tested the route on my old zumo 210, works without any problems.

Route looks normal in Tread for me. In my XT2 it had to be recalculated as it said the mapping was different.

The XT2 route didn't go directly between Cafe Rododendro to Passo di Gavia, but that might be down to different avoidance.

I had a quick look and to me the route looks OK. But I dont have an XT2 or Tread, I'm still on the XT.
This makes me think of reports that routes in the Alps are messed up due to incorrect Traffc info. Those reports were about the XT and not the XT2. But still you could check if it is possible to disable Traffic info on the XT2/Tread.

Just an idea.

Edit:
This is the link to a German site. (Not a problem for you I assume)

Not all the poi's / waypoints are correct placed on the road. Please correct that. Tread can influence a route. In basecamp covert to a track. In tread or on the XT2 convert the track to a route. Recalculate off. Start the route whie on the route and you will be fine . Succes and regards

I tried making a route from the track on the device. It does calculate the route correctly, even though it takes literal ages. Of course then my waypoints are not on the route anymore, which makes the whole thing kinda pointless, I need to be able to see how far and how long it is to the next point.

Amazing how the zumo 210 is faster, transfer route device. Import and ready to go.

I've not yet loaded this into my XT2, but notice that your screen shot doesn't show the position of your bike. There is no start flag - you would be able to tell better by zooming in. I can see the top edge of a finish flag. The rest are only Via points and Shaping points. Impossible to say whether or not these have been created as Waypoints. (For Garmin, Waypoints are saved locations, not points on a route).

This might suggest that it has not yet saved your current location, so it could be assuming that you are at lat 0.000, long 0.000. It may be plotting a straight line route from 0,0 to the start. One line certainly seems to be heading down the 0 deg longitude line approx down that eastern coast of Spain. I can't explain the second line though. And it seems that no route has been calculated - but impossible to tell for certain - are they all straight lines ?

I remember when I got my XT - that until I had ridden a few miles with it, many of its navigation features didn't work. It arrived during covid and we were not allowed to travel, but we could have 30 mins exercise - so I took it walking with us. It had got a good satellite fix, but the routing was was all over the place. Traveling at 3-4 mph didn't count as moving. It didn't start to work properly until it came with us on an essential shopping trip in the car. After that it worked even on walks.

There is a file called position.gpx in the "Internal Folder / GPX". This updated quite frequently as you move along, so that when you turn on the Zumo it does not have to work out where you are each time - which can take a few minutes. Satnavs really need to know approximately where you are and what time it is before it can get an accurate fix on your position. Once it knows has those two pieces of information, it knows which satellites it is getting its data from and where abouts they are in the sky.

Out of curiosity I'll delete my position.gpx and see if the results are the same.

NB I do not know the Tread GPS device, but the above has been true for all my previous Zumos -except one of the XTs introduced a feature which stopped the current location wandering about the screen when you are not actually moving. It seemed to do this by doing what it always does - calculating your position - but not updating itself if you haven't moved very far since the last position fix.
Watch the screen - my 590 shows the bike icon wandering all around my house and garden. My XT2 does that a few times but then it stays completely still - and has no idea which way you are facing.

With the XTs it seems that the very first position fix is only recorded after you have moved from 0,0 at a reasonable speed. Somewhere between 4 and 30 mph.

Back again a good many hours later.

I cannot make my XT forget where it is. I didn't delete Position.gpx - I changed the lat/long to negative - so NewZealnd ish. I thought that if I deleted it, it might have a backup copy somehwere and restore it. It wasn't fooled. It hadn't located my position befor I turned off the GPS - but it still placed my bike at home. So it restored the value from somewhere anyway.

But turn you satnav on and take it for a ride in the car for a few minutes. Try again.

Your route and the current Garmin maps do not match up. The roads are in different places and your points are off.

Here is a suggestion:

Find out what maps your Tread Unit has loaded. Make sure that the relavant Europena one is selected. Any others that you have downloaded that are not from Garmin - untick them.

Load your route into Basecamp. Make sure that the maps are the same as the ones that are on your Tread device.

Click on the route and make a track from it.

Then double click the route name and select recalculate route.

Using the back curly arrow and the fwd curly arrow - you can reverse that recalculation and bring it back again.
My recalculate magenta line follows the garmin map of the roads exactly. Your original rout did not.

BUT - it also altered the route in a couple of places - so the track will tell you where it went.

I alway thing it is rather risky plotting a via point at a cafe or a petrol station. You may not actually pass through that point, and I assume the Tread Unit behaves like every Zumo I have ever owned - it insists that you visit via points. My preference is to have a Via point before or after the turn off - plotted on the main road (I prefer after) . Then use a shaping point to take you to the cafe or fuel stop. That way it doesn't matter if you don't visit the actual point at the cafe or feul stop - once you get back to the main road and past the vai point, it will carry on navigating ahead.

In the trip list, clcik on 'Center Map'. It is spelled incorrectly for us UK pedants, but it still works ! Then clcik each point in trun and see where the points are plotted. Notice also where the route differes from the track (which was created from the original route).

The trick is to modify the route to match your maps.

Then - having ensure your satnav is talkign to you now you have taken it out for a ride in the car
and having got all of your route points and maps talkimg to each other.

Try uploading it again. (Oh give it a different name, cos having two different routes with identical names is bound to confuse you.
Tread will probably add a number 2 to the name of the second one - but the name of your trip is so long, that the SatNav probably won't be able to display it !

Let us know !!
