@proofresistant - I was just wondering whether there was a TM created trip file present in .System/Trips.
I don't quite understand what you find surprising and what exactly you are referring to.
However, in cases where I specifically observe synchronization problems, I use a fresh system without existing GPX or trip files also.
If that is the case, then it answers the question. Thank you. I'll answer the other part of this in the development pages if you wish. I don't want to get to technical on these pages.

Gpx files on the Sd card are treated differently from gpx files in internal storage. They are not altered in any way, but they still suffer the same route point modifications when the Tread app is involved and/or when synch with the tread database is involved.
When I import directly to the device, I always do so from the SD card.
But the Tread app synchronization doesn't handle/modify GPX files, or have I overlooked something?
Mainly the shaping points of the routes (trips) that are then in the device and the Tread app are manipulated.
Sending to the SD card is the safest method. Data (route point names and locations - particularly shaping points, but sometimes via points) are relocated and renamed:
1) By the Tread App itself on ipad and android phone when creating a route.
2) At some point in the transfer from the remote device (iphone, ipad, android phone) to the Tread database, to the Zumo. I did find out at what point it happened in a few tests. I'd need to look back through notes to be certain.
3) When importing data from a gpx file into the XT2

(
Gpx files in internal storage files have track data and waypoint data removed from the file)
What do you mean by that?
As far as I know, the GPX files themselves are not changed.
All relevant track and waypoint information is still stored in the .System\trip files and device Explore DB (yes, Waypoint data is also stored in the device's Explore DB).
I don't know what data the Tread app or the Explore page still has and how it is stored. In any case, at least the shaping points with their coordinates are there, even if their positions/coordinates have been changed for some reason.
If you put a gpx file into internal storage then when the Zumo is booted up after transfer, it seeks out new gpx files and processes them.
- The Waypoints (Those defined as waypoints at the head of the gpx file before the start of the route definition), are read and imported into the Waypoints section of Explore at start-up.
- Tracks are Read and copied into the Tracks section of Explore, but only after selecting a track to import. Any track. It will then import all of them. The hundreds of lines that make up a track between the <trk> and </trk> tags in the gpx file are then deleted from the gpx file. This means that they cannot be imported again if they are deleted using the XT2 menus in the Explore section.
- Waypoints can be selected to import a second time, but a duplicate waypoint is not created in the XT2. The definition remains in the gpx file.
- See app.php/XT2-P338b - and the following page.

Being able to drop a file into .System/Trips by BT would be brilliant. You could do it with the gpx files into the gpx folder on the XT1 with the Drive app, but not with the XT2 / Tread unless synchronisation is enabled.
Hope dies last.
I don't understand Garmin. The XT2 and the Tread app have been around for years now, and it's still not possible to transfer data “without problems.”
Personal opinion only. I don't think that they care a great deal. They seem to be addressing the problems of the majority. And it seems that the majority cannot plot a point on a map, or prefer to use programs from other sources which have different maps. With the technically brilliant Zumo 590 this caused problems - people were complaining because it forever taking them to route points that they had not visited because they were plotted incorrectly.
So instead of producing a manual to help customers do it properly, they cater for the largest area of the customer population normal curve, somewhere to the left of the mean - and make the routing ‘idiot proof’. It gets you to your destination but it doesn’t necessarily follow the roads that you want to ride.
So you plot a point. By default, the XT2 assumes that every point is only approximate- eg that it has been placed by using a different map without zooming in. It seems to use those coordinates and finds a known point close by in a database. And just in case there are a couple of possible roads to choose from it assumes that you want to be on the faster road. So the point changes and the name changes to what was obtained from database.
So I think a lot of effort has gone into this approach because it sells more units. And they don't get many complaints because the majority of people on well known forums seem to advise using tracks to fix the problems. Tracks don’t change. So they then get the Zumo to convert the track to a trip, and they have no problems.
Except: Track-Trips are the reason that we have problems with RUT behaviour. So they turn off automatic recalculation, and that solves that problem. And the majority seem to be happy with that solution and that is perfectly fine.
They seem oblivious to the fact that they have paid £550 for something that is not that far removed from a £2 map book and a highlighter pen.
Which for say a tour operator wanting to share routes with customers, this would be ideal.
Years back, my first look at TomTom led me to believe that they used tracks rather than point to point navigation. Whether or not that impression was accurate, I preferred the point to point method that I saw on Garmin. Take a deviation from the plotted route, the Garmin would find a new way to get you to the next point. That was what I wanted. Garmin seem to have moved from that and for me, it is not for the better. The 590 remains the most reliable navigation device that they have produced, in my opinion. Pity about the screen and battery though.
