Interesting
I just tried this again.
I set my home location by doing Change Home Location>GPS (I was AT home as suggested above). Then I went away, tried to navigate to home and got 'no route found' This is what happened before and I did not try again earlier.
However, I tried to route to a POI nearby and it behaved as you suggested. It gave a route that started at the nearest road and lead to the location. Interestingly, this route made me walk *away* from the destination to reach the road end and then back. This latter issue would not be a problem if you were far enough away.
So, I made a POI of my 'home' by selecting the GPS fix and gave it a name. Then I changed my hope location to the POI. It now routes to 'home' the way you described.
I guess that the lesson is not to set home (directly) via a GPS fix but via a POI (or a favourite?) even if the POI is, itself, simply a GPS fix?
Thanks for mentioning this as it really helps. It also underlines the effort of software testing when there are so many ways to do things; some of which work and some not. It is great to have a forum where others can say 'wait a minute, that works for me'
