Thank you for those observations
@TheoTiger - and welcome to the forum.
My solution is to
* Have Tread on the phone
* Prevent it from synching data with the XT2.
* Use only 'Saved' routes.
What follows is an explanation

My solution is not to install the TREAD app on my phone.
That works, but you may have to perform a system reset on the XT2 to prevent it from trying to synchronise. It will fail of course, but it doesn't know that until it has tried. That
may cause other issues which affect Bluetooth behaviour. I don't know for certain - but I have suspicions that phone call, recording of track logs, music playback may be suffering.
One thing I have found that works is to delete the Tread App. Reset the XT2. Start again. Install Tread but this time reject the option to store data / enable synchronisation. You only get that option once. If you accept it, then it is set up for ever -or at least until you return your XT2 to factory conditions. If you don't accept, you have to dismiss a couple of attempts to get you to set it up.
That set up gives you access to the traffic, weather, roadwork, fuel prices from the Tread App on your phone but the route stays intact. You can turn off Traffic on the screen system options.

You disable recalculation. However, if a road closure or major traffic jam is detected on your route, it will still recalculate a new route. The result is that your planned route gets ruined.
That is correct. If you allow Traffic, the XT2 will plot a new route without giving you the option. If you don't allow Traffic data, then it doesn't. The data is pretty good sometimes, but other times - eg night only closures - can be annoying when you have detoured unnecessarily.
Tracks never get altered ( unless you turn them into a route to navigate). I find that the best combination is to show the track on the map as well as the route. I show the track in black and I have modified my theme file to show it slightly wider than the route - so the route has a black outline to it when it is following my plotted roads, and I can see instantly when it deviates.
When you say that your planned route gets ruined --- Do you mean that it no longer passes through your original route points ? That behaviour is largely eliminated by disabling the synch / storage on the Tread database. However, a separate issue can also cause this:
In some circumstances - if an
imported route - ie one loaded from a gpx file - is recalculated, then it subsequently behaves differently if you deviate from the route. It no longer takes much notice of your route points and instead it tries to get you back to the original magenta line by navigating you to the closest point. Often if you deviate, the closest point is where you left the route. Behind you. Thereafter, the closest point is always behind you. It's a loop that it cannot escape from. It's something that I called RUT behaviour - because it seems to be stuck in a rut. That is what 'appears' to be happening from numerous tests I have carried out.
But it never does this with routes that are not imported. Routes that have been created and saved on the XT2 itself. So there is a cunning fix to this. Make the XT2 think that your gpx route is a saved one.
The XT2 has a 'Copy' facility. Load the route, make a copy of it (spanner menu, top left) and save it with a name to distinguish it from the imported one. I out an @ symbol in front of the original name (I was looking for a (C) copyright symbol, but the XT doesn't have one.)
Load the copy and that will visit your route points in strict order, but it will allow you to forget about shaping points if you rejoin the route after the missed shaping point.
Note that if the XT2 has to recalculate a route, eg if you press 'Skip' then it may well alter the entire route - but it still has to visit all of your shaping points and via points. It is up to you to plot shaping points to keep it in your preferred roads. That doesn't mean plotting many more. It means plotting them more sensibly. With Tread active - Tread will move your shaping points onto its preferred route. With Tread synch disabled, this doesn't happen.
