Weird navigation MRA to Garmin Zumo XT
-
Thank you for all your answers and suggestions.
@Nomko-Nomden
Yes, I do update my Garmin XT regulary (the firmware and the maps). Thank you for the suggestion about placing the point after the rounadbout. Some folk on the XT forum also suggested this so there is something true about it. I will do my best to remember this when drawing the next route and see if I will have better luck.
(but also note that on that same trip I had another similar glitch which does not involve a roundabout; I just didn't have time this morning to create a screen shot from the XT)Also I think I have a recalculation turn on, I have to check. I also don't quite understand how does device reacts when I turn this off, I have to read about it some more. Because I do want the XT to reroute me if I do some unplanned turn because of the sightseeing, road block, or whatever reason. That is why I also use shapping points (not only via) to easily skip them during route if need be.

Thanks for taking your time to do this test, I really appreciate it.
It would solve all my problems if I would see this odd behavior when planning on MRA. Then I would play with positioning the points. But in reality, when I am happy with route in MRA, I just send it to XT, and don't look at it anymore (until riding). I just trust the process, that everything should be ok.@Guzzist
I understand and I also find Zumo XT not ideal. Perhaps I will one day change to these new Andorid devices and go with MRA Next navigation, but for now I must live with my XT. In general it works 100%… 50% of the time

I understand your doubt about the recaclulation turning off.
But the main reason to do this which is also suggested on other forums is that, if you have a route and you want to follow that route from A to B as it is ploted and as it is intended, you turn it off to avoid any deviations/reroutes/etc.
I get the point that you want to be able to take an unexpected turn somewhere to the left or to the right. But kep in mind that your device might direct you back to a waypoint that you skipped.

I've tested this route on my XT and it works fine with no glitches.
My calculation mode is faster time.
When you open the route to navigate it looks like this.
If you set nav preferences to Garmin Adventurous Routing you get the little mountain box
When you press this before hitting go you can use the slider to make the route more wiggly.
I don't use it as it can bring you round housing estates and city streets and I prefer to put enough shaping points in to pin the route to the roads I want to be on. Could this have created your issue?
These days I use MRA for navigation and my Garmin for tracks and proximity alerted POI's. But if I do use it for navigation I run a track of the route to see where they diverge. Yellow track in this case beneath the magenta line.

Thank you @Mzokk for taking you time to test. I am wondering if you would put another point in the middle of the route, where the sign 419 is on your image, would you get the same problem as me?
I am aware of the Adventurouse routing option, but I also didn't find the use of it. The idea is great and it is also one of the marketing reasons why I bought the Zumo XT, but in reality - as you said - it rarely discover new twisty roads in my area. In reality it actual drives me through the private/estate roads and city traffic.Anyhow, I dig up some more of the other similar cases I got - all these are just from the last two rides
And non of these has a roundabout or two lanes road.

For some reason, this happened to me too last weekend. I have a xt wirh a route made in myroute app. Exported with gpx 1.1, for a route of 350km. Expanded with 100 points (all soft and checked). When i open the route in rhe xt, it is as planned, but only after a few km's it suddenly changes the complete route to about 550km's. It gives similar behaviour as you describe. Sometimes it even directs me in a linear direction,like i'm a plane. It happened with a round-trip, so from A to A. I had another trip made from A to B the same way, didn't have any problems there. Made with the same settings and same export mode. Ended up following the route as a track, but that is far from ideal, as there is no guidance then in the xt. There must be something happening in the xt, because BEFORE i start to navigate it is all ok. Settings are as MRA suggested (faster time, re-calculate on). Doesn't matter if i change any if those, still keeps happening. Hope someone can help with this....

This happened to me too last weekend. Never had problems untill now.
I made a route with MRA from A to B, exported it with GPX 1.1, calculation "faster time", re-calculation on, no problems.
Made another route the same day from A to A (roundtrip) with the same settings. When i start this route, after a few minutes of driving, it changes the route from 350 km's to about 450 km's.
All points (soft and checked) go crazy (i have 100 points expanded). Doesn't matter what i change in the XT, it still goes crazy.
At every point, it turns around, makes a weird curve, or even goes from point to point in a birds-view (like i am in a plane). Changed the route in MRA, so the start and end are far from eachother, doesn't make a difference.
All i could do, is follow the track, but that is far from ideal, as it doesn't show turn by turn navigation.
This has never happened to me before, so it must be something in the XT i guess.
I have everyting updated.
I made another route for my girlfriend at the same time in another area (she has an XT too) with the same settings and also from A to A (roundtrip) and she didn't have any problems. Wish i could show some screenshots, but sadly not possible as i am home now.
Hope someone can help us with this. -

Hope someone can help us with this.@Fredrossi sounds like either the XT never recognised you passed the start point & was then trying to reroute you back to it or a standard case of the garmin xt getting into a RUT, check the garmin xt forum to find out more about RUT's
if you continue to leave recalculate ON then you will see a lot of this crazy behaviour -
Thanks for the reply and link, but i don't think it's a RUT. The gps is showing the route as planned, but when i pass the first point, it changes the complete route : every point is still there, but it gives some bizar routing at every point, and then goes to the next point, where is does that again. So the route goes from 350 to 450 km's.
It doesn't let me go back to a previous point, like it would for a hard waypoint, it just goes crazy on every point and then goes further on the correct route.
If i stop the route and start again halfway, it does the same thing.
It doesn't send me back to the beginning either.
I have been working with Garmin since the gps 12 and the streetpilot III. This is a first for me to discover such weird things.
Recalculation ON is what MRA suggests, and worked perfect before, so what happened here i don't know, setting it to OFF might work, but that looks like a workaround to me, not a solution.
Even stranger that the XT of my girlfriend didn't have this issue. In about 2 weeks we have a roundtrip, about 170 km's, will see what happens there.
For now, i just don't know how to reproduce or resolve it. -
I am just wondering if this is an update thing, since I didn't notice this kind of behavior last year. All tough I don't have such an extreme problem as @Fredrossi.
@Fredrossi does your girlfriend update hers Zumo regulary or perhaps not?

She does , both are latest. I've been reading this site : link text
Could be something to do with this, but it looks like a difficult workaround too and not permanent.
