Note sure if you intentionally marked this as resolved? If you did then please disregard this.

It's hard to understand your problem with knowing the start and end coordinates of the route you are talking about. Knowing that would help.

It might be relevant that this road was incorrectly marked as oneway until as recently as October 2022: https://www.openstreetmap.org/way/6117800/history/19
Therefore, I wonder if your device is using an old (<=2022) copy of OSM data? Accordingly, you might need to update your device to use a more recent copy of OSM data.
