Yesterday I created a route from York to Cockayne in the North York Moors and transferred this to my Garmin Explore. I noticed that the Cycle Travel route doesn't 100% overlay the Garmin map - which is not something I have seen before. By this I mean that it looked as if there were two roads running in parallel with each other for large parts of the journey.
I have created lots of routes previously with Cycle Travel and have never seen this problem before.
Mostly the lack of overlay didn't matter too much but it can be confusuing when you had several roads near to each other, particularly if you are trying to navigate through a town.
I created the route on my laptop with Cycle Travel running in a browser.

I would be interested in hearing about this!
Do you know what map data your Garmin is using? (This is often shown in an on-screen credit.)
cycle.travel uses OpenStreetMap data so if the Garmin is using (say) TomTom or Here data, it’s possible the roads might have been plotted differently and they won’t line up.
(Looking at OSM data vs Ordnance Survey for this route, there is indeed an offset - I wonder if the OSM data was traced from old historic maps in the early days of the project before we had access to good satellite images!)
