Weird navigation MRA to Garmin Zumo XT
-
Hello everybody. I am a gold MRA user and I use MRA to create routes in HERE maps and transfer them to my Garmin Zumo XT (using Garmin Drive and gpx 1.1 R/T/P).
I noticed a weird behavior lately and I cannot understand what is going on. I first tried the Zumo XT forum, but couldn't get any real explanation there...Just to clarify, I have my Zumo XT updated all the time and I created the route in MRA freshly in the morning and drive the route few hours later on the same day.
This is how one part of the map looks on MRA - and this is exacly as I want it:
This is how it looks in Zumo XT maps and the black arrows shows how XT wanted to navigate me through this section:
What is weird though, this is the original map on my Zumo XT of this section, when I don't have navigation active (it has everything connected and it shows that Zumo XT knows which road is the main one):
On the Zumo XT forum some suggested that I placed the shaping point in the wrong lane on the road, but from what I see this road doesn't have multiple lanes (not on MRA and not on Zumo XT)...
I also checked my avoidance settings, but nothing helped there. Also MRA has the "shortest route" and Zumo XT also has "shortest route" selected.
Any ideas on what I am doing wrong?
It is not really a deal breaker, but it is really annoying and I get at least one of these on every trip...I thank you for your replies.

It looks like your Zumo thinks a right turn is not allowed. It could be a map error on the Garmin map.
I am just an enthusiastic MRA user, and hope you will be one too!
Most motorcycle problems are caused by the nut that connects the handlebar to the saddle.

Thanks for your comment, but I got these kind of glitches quite a lot lately... not sure if there are so many map errors all of the sudden.
I also thought that HERE maps in MRA are the same maps as Garmin's Zumo XT maps. Like same-same. So if there would be a map error then I should also see it on HERE maps in MRA, right? -
@Con-Hennekens @Boštjan-Kreutz
Garmin XT (which i also have) uses the NTU maps which is basically the HERE map with a few adjustments done by Garmin that turnes the HERE map into the NTU map.@Boštjan-Kreutz
The suggestion made by that person on the Garmin XT forum makes only sence if the 2 lanes are splitted by a central reservation. If the two lanes simply lie side by side without a separation such as a central reservation than it does make no sense.Also, the route is determined by the way the routingpoints/waypoints/shapingpoints are placed. Routes made in MRA always goed from 1 to 2 to 3 to 4 to ..... (you get the idea).
Just to clarify this:
Have you ever updated your Garmin XT device? Garmin provides updates on a regular base.What your device is showing looks like some glitch to me. Check if you can update your device. In 99,9% of all cases updating the XT solves most problems.
Just 1 hint from me which i always do, i always places routingpoints/waypoints/shapingpoints after roundabouts. Just to be sure that my XT is following the road as planned.

It is recommended for XT users to turn off Automatic recalculation
Most will have this turned on but i have notices (and read on other forums) that turning it off also avoids "crazy stuff". -

the 2 companies update the maps at different intervals,
but I do not think the map is the problem here,First I used a simple route with 2 points either side of the roundabout, just the start green flag & the finish chequered flag, the simple route on my Zumo XT was good & the simulated path taken was correct
I then added a middle point before the roundabout in a similar location as shown in your picture
My XT gave a crazy route similar to yours
For the last test I just moved the middle point to the north side of the road & the route works correctly
For me this is just another crazy case of the Zumo XT doing stupid routing & why people keep repeating that you have to place the points exactly on the road.
This case proves even when the points look correct the XT will still get it wrong, it looks like it is trying to get to the little side road to the south towards the riverMRA navigation is a lot more, a lot lot more tolerant of point placement
Because of crazy stuff like this it is why I gave up on the Zumo & why it now sits in the bottom of a drawer
As I have said many times, IMO the XT is a piece of $&!7(recalculate on/off makes no difference in this case)

Yes of course, but they are not on the same version.

@Boštjan-Kreutz that's one of the reasons, I put the Garmin device in the ash tray. Since I use MRA-Navigation, I'm happy.
o.k. may that's not a solution you did expect - but I'm sorry, I don't have a better one. -
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.
@Brian-McG
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
