I save my routes to the micro SD card I've got in my XT, that way you can do anything you want to the route in the Trip Planner, and know that an un-amended route can still be imported again.
Just an “ off the wall “ notion , I am assuming ( maybe wrongly ) that the GPS satellites are under USA control . The USA are heavily supporting Ukraine at the moment ,, is it possible these signals have been intentionally degraded in certain areas for some military reason ?
Ie to prevent their very accurate use with Dgps for weapons guidance , there have been pics of posh Russian fighters ,- with a cheap garmin stuck on the dash .

That is an interesting hypothesis but one that fails, I’m afraid.
A. My phone, which relies on the same satellites’ GPS signal (augmented by the phone’s ability to triangulate its position from any phone masts it can ‘see’) performed seamlessly, once I had taken it out of the cubbyhole on my 1600 and put it into my tank bag instead.
B. The newspapers and the internet are not full of stories of every Tom, Dick and Harry getting lost on their way to their mum’s, as their GPS devices are on the blink.
I would guess that, if the Americans has de-tuned their GPS satellites, someone by now would have noticed. You might though have accidentally launched a new conspiracy theory, which the Janitor will now pick up on as a part of the Plan. It’ll become the truth by teatime.
Perhaps Richard they noticed you travel extensively throughout Europe and decided you were doing nefarious deeds for Putin.

Now that is more likely. Or maybe it was some ardent Brexiteer, determined that I should be lost forever in the hell hole of the Socialist EU, that tampered with my XT?
You should be able to re-import it from route planner.

Wapping. I'm s bit late to this thread, but I'm wondering if it was the heat that scrambled your xt? 
Er-Mino - you made a comment I'm interested in - "Not if you ask the XT to recalculate it."
How do you do that, I mean stop it recalculating?
That recalculating thing has screwed up many trips (always fixed though!). I've permanently fixed it by inserting limited waypoints.

It was in Luxembourg, in early November, the mercury hovering around 11 degrees.
I past by there around the same time. Had all the heated clothing on. The sun and lovely autumn colours must have conspired to make me think it was still summer
Joking aside. Pleased to sayi haven't had the problem you've described. But I have very definitely had a couple of times when the unit has gone AWOL and clearly something wasn't right. But it always jarred itself back on track...

If it did it once or twice, I’d not have worried. But this was as regular as clockwork.
I have now got my refund from Amazon and have bought a new one.

I have read here and there of people retiring/replacing units because of issues. Maybe you had a duffer

Yep.
Just to explain and, to make clear, this is my assumption on how it all works (a lot of it based on the explanations and links provided by Wapping over here over the years). I might be wrong here and there, please correct me if that is the case:
You load a pre-defined route from BC to the Zumo.
Route is composed by the following points (numbered):
1. Starting waypoint
2 to 20. shaping points: indicating which roads to follow, based on a certain type of calculation, say "shortest distance".
21. Waypoint: mid point of the route, for a stop, added by the user
22 to 30. Again shaping points leading to...
31. Arrival waypoint.
When the route is loaded on the GPS it would keep its original shape, as seen on the computer.
If I ask the Zumo to recalculate it, and the Zumo calculation settings are, say, faster route: Waypoints 1, 21, 31 would be untouched. All the shaping points in the middle will be altered to make you follow the fastest route available.
Note: the same happens if you alter portion of a route using "start from nearest point" or other functions that would force the Zumo to "re-imagine" a portion of the route, etc.
To prevent random recalculations... easiest thing would be to disable auto-recalculation of the route.
Or to design your routes with a lot of waypoint close enough to each other – that is pretty much the way I build my routes on Basecamp, with the only difference that I place a lot of shaping points, not waypoints.
But, the method I found that gives me best results is:
1. Plot my route in Basecamp. Lots of shaping points, a few waypoints, usually for stops or bits where I can interrupt/restart during the day or consider alternate ways.
2. Create a track from the route.
3. Upload both to the device.
This way, you can have the track displayed under the route (if you set the track width to the maximum size and in a contrasting colour, you'll see it as a keyline around the route). If/when the Zumo recalculates a section for any reason (deviation, traffic, etc.) you can, at glance, see how much the newly proposed route will differ from the original and decide what to do.
Only downside: you don't have alerts/spoken navigation with the tracks, but I'm kinda used at following them by glancing down at the Zumo screen when approaching a junction or similar.
Goes without saying, all this with the bi-dimensional map. A la paper map.
Hope I didn't confuse you more.

Of that I am pretty much sure.
Thanks Er-Mino. I'm particularly interested in your idea to also create a track, then upload that also. I'm going to give it a try 
Ref the waypoints. What you describe is much as I am now doing, but I have to confess it comes after lots of cock ups and the BC learning curve. I basically use the waypoints to pin the route to its overall tend of direction and pass through places I need to. But I quite like to leave the bits in between open to recalculation so i am free to make detours or even be diverted by closed roads.
I want completely clear if the shaping points are unaffected by recalculation?

Do it. Lifesaver. Especially on long trips, if things go pear shaped.
My understanding is: they are.
If you don't want to sat nav to change them, convert everything to waypoints.
With the display track on screen, when running the route, isn’t it a problem that tracks used from say yesterday’s routes are also displayed? Making it sometimes difficult to see which track is the correct one? This is what I found, meaning that I had to find yesterday’s track and turn its display off.
