The fix for RUT occurs in the .trip file which is the route file once imported into the XT and XT2. In simple terms, the RUT fix simple changes a single bit in the .trip file, and that bit is the difference between the satnav recognizing the route as a "Saved" route or an "Imported" route. "Imported" routes are subject to the RUT phenomenon, "Saved" routes are not. @JFHeath and @FrankB would be the ones to explain this in greater detail.

Edit: TripManager fixes RUT as the routes are transferred to the device.

@giuseppe66 Look at the list of trips in the upper left of the Trip Manager Window.
If the box at left is checked, RUT is fixed.
If the box is not checked, you can check it right there, which will fix RUT. If you use Trip Manger's "Send to" button to send your gpx files to the zumo, as .trip files, RUT will be fixed automatically and the checkbox will be checked.

I can correct the RUT with your program (thanks a lot) by selecting the .trip file, but I have many GPX files that I download via Myroute in 1.2 format (but I can use 1.1 format if you recommend that). I have the files on my computer and wanted to correct the RUT directly on the GPX files before inserting them into the XT2. Is this possible? Thanks for your reply, and sorry if this is a question others have already asked.

Yes. It does not correct an existing .trip file, unless it was created by TripManager. You should delete the route from your XT2 screen - otherwise you may end up with two routes with the same name. Trip manager creates a new trip file on the XT2 which you do not have to import. That trip file will have a recognisable name, the shaping points and via points will keep the name that you gave them and they will be plotted in exactly the same position.

Trip Managager does not calculate the route. The XT2 has to do that using the points that you have plotted - the via points and the shaping points.
The single value that indicates to the Zumo whether a) the route has been imported from a gpx file or b) has been created and saved using the XT2 is also set.

So yes, you can use Trip Manager to create .trip files from routes in your existing GPX files on your computer.

If you have routes already in the XT2, you can prevent them from displaying RUT behaviour:

Apps Icon (4 square blocks) -> Routes -> Spanner -> ‘Copy’

Give the route a new name. I use an @ symbol to distinguish it - eg @OldRouteName.

That makes the XT2 believe that the route is one that is saved by the XT2 rather than an imported one, and will never display RUT behaviour.


MRA Routes

GPX v1.1 includes the via points and the shaping points, but it does not include the hundreds of ghost points that tells the zumo which roads MRA used to plot the route. The Zumo has to work out its own roads between your shaping and via points. It may use different roads to travel from one route point to the next.

GPX v1.2 includes the via points AND it includes the hundreds of ghots points so that when the XT2 receives it, it plots exaclty the same route. As long as the XT2 does not recaclualte the route. That is where the problem lies with v1.2 - If the XT2 recalculates it, then it will produce a very different route becasue gpxv1.2 contains no shaping points. It only contains the Via Points. And it is quite likely that the XT2 will recalculate your route. Map differences, route preferences different, skipping, going off route, temporary loss of satellite signal, road closures coming from your phone Tread app.

With the XT2 it is safer ro have the vai points and the shaping points. If you want to know where the original route went, then plot the track. That can be displayed as well as the route (it will be underneath it). If the route changes, you will see the track going in a different direction - but the track will not change, even if the route does. Follow the track, the XT2 will calculate a new route (eventually). MRA includes the track of your route automatically.

RUT Behaviour

One of the sysmptoms of RUT behaviour us repeated U turns. The XT2 will turn you round half a mile ahead, and it alerts you to the fact that it is expecting you to go a different way. Turning U turns off does not prevent RUT behaviour. It just hides the fact that it is happening. Like taping up your nose when you have a cold.

If you turn it off - you get no such alerts. One example I have seen when testing RUT behaviour: I was expecting it to turn me back, but forgot that I had turned off U turns. I was on a quiet country road with no other roads nearby. My satnav showed a turn 7 miles ahead. Ok. I'll play this game, lets go and see what happens. WHen I reached the turning, it was a housing estate. Around the houses and back onto the road that I had been on, facing the other direction. Then the same 7 miles in the other direction. On tour when you don't know the area you would follow these instructions, not realising what was happening.

Repeated U turn requests can happen in other situations - quite correctly.
eg1 : if it is quicker to get to the next route point by turning back. That is correct behaviour
eg2 : The Zumo does not recognise that youhhave passed throught he start point when you set off. That is operator error !

Many thanks for the perfect tutorial on how to use both the TripManager program and the MRA and ZUMO settings. It's thanks to people with your expertise and patience that this Zumo user community is able to solve many problems that should be solved by Garmin!! Thanks again. Just so you know, even though I have a Gold subscription for MRA, I use OpenStreetMap maps because they are less error-prone than HERE maps. Have a good evening!

Thanks for the kind comment.

I have another question.
1) I generate the GPX file with My Route with export in 1.1.
2) I see it in the right window of TRIPMANAGER (for example, file name GIOVANNI.GPX).
3) I send it to the Zumo and it appears on the left in the GPX section, but I still don't see it in the TRIPS section.
4) I restart the Zumo and after importing the GIOVANNI.GPX file, I have to import it and then I see it in the TRIPS section.
5) The GIOVANNI.TRIP file is not checked.
Question: Is the RUT function active even if the GIOVANNI.TRIP file is not checked, or do I have to manually check the file?

@giuseppe66

I think you have to click on 'Send To' and in the dialog that opens select the option 'Trips'.
In the PDF it is 'method 5'.

@giuseppe66 If you use the arrow button in Trip Manager that simply copies the gpx file to the zumo, just like if you transferred the file using Windows explorer or an sd card. It is purely a file copy.
In that case, once copied to the zumo, you have to import the route. A .trip file is created by the zumo during import and the route is marked as imported in that .trip file. The check box can be used to change the flag in the .trip file from imported to saved, which fixes RUT.

The easier way is to use Trip Manager's "Sent to" button, select the "Sent to Device" tab and then check the box to create "Trips (.trip)" In that case, Trip Manager will create a .trip file and send it to the connected zumo. No further import is needed. The trip is automatically set to saved, which fixes RUT.

.trip files need to go into "zūmo XT2\Internal Storage\.System\Trips". Trip Manager should be configured that way by default.

... and, by the way, Frank deserves all the credit for creating, maintaining, and continuously improving Trip Manger.
I just help explain how it works. Hopefully I get it right most of the time!
