Re: Garmin XT & Tyre
Posted: Tue Mar 29, 2022 11:21 am
I looked at Tyre a long time ago and still have the installation files, so I reloaded it onto my PC - to investigate @woodyflyer's information. I hadn't bothered with that before because I was using the 660 at the time. So his contribution mentioned things that I hadn't investigated.
I'm curious because I now have a lifteime subscription for MyRouteApp which was developed from Tyre. So I wanted to see the progression - see if I have missed something on MRA.
The following information for Tyre may be useful:
Tools -> Preferences - > General Tab (click the image to see the screenshot in better quality)
I'm not sure precisely what each of these do, but these options are what I had set when I checked out the Files Tab.
Note the default setting of Garmin at the bottom.

GPX new Format only - ensures that the GPX file that is created includes both shaping points and Via points - exactly as you have entered them. If Old format is ticked, then you just get route points - no distinction between Vias and Shaping.
Use Garmin waypoints/favourites - these transfers EVERY route point into a favourite / waypoint. Now this has a big advantage in that because every route point is a favourite - whatever you named it as, the XT will not give it a new name. This is extremely useful on the XT if you have to skip a point and it tells you what the name of the next point is, To recognise it, you need it to show your name - not some name that you have never seen before. The downside is that you end up with a load of favourites in your XT, which you don't really need.
Use Route Tracks - This ensures that the GPX file that is created also contains a track that reproduces the blue curvy line on the Tyre map. This is a good idea, since the XT can show the route AND the track at the same time. And while the route may recalculate, the track stays exaclty the same. So if the route changes for whatever reason, you can see from the track where it has changed and decide which one to follow.
Route Recalculation.. The gpx file of the route should - in theory - be identical to the route that is produced in Tyre. Tyre uses all of the right commands to make it stay in place. The XT should not recalculate it. I fth eroute is every recalculated, itthe XT will work out its won route which will probably be different from that proeduced in Tyre.
To export the route simply Save as .... and select the gpx file format.
What Tyre didn't seem to acknowledge (unless it was sorted out in the professional version) is that if the maps are different, as soon as the route is loaded into the XT, it WILL recalculate it. The Tyre server is no longer available, so the maps will be different. Even the MRA app - which uses the HERE maps that Garmin uses - the routes are recalculated on loading. In fact, MRA doesn't bother transmitting the plot of the route in some of its gpx export formats - it just transmits the route points and lets the XT calculate the route between the points from scratch.
There is an option to make any point in your route a Waypoint. You can then export the waypoints separately. I don't know if this adds themt o the route file though, and cannot find out because it needs the professional version of Tyre - not the freebie version that I am using.
Once you have your route and your roue points set up as Vias or Shaping - then you can save it as a gpx file.
Make sure that you drop it into the Zumo XT->Internal Storage/GPX folder.
