8th item in navigation settings is "Routing points on not closed roads (Snap routing points only on roads that are not closed)" with a checkbox on the right.
Tuky, which language is set? if you don't see any text there, re-install newest version - maybe that will help.
If the text is there and voice only complains about a not found string, ignore it.
my version it's 21.3.8 and I use in Italian Language.
In setting\navigation\ I have 10 voices:
1) Modalità routing
2) Tipo veicolo
3) Mostra pannello
4) Autozoom
5) Vista 3D
6) Navigazione dettagliata
7) Snap GPS ON
8) String not found
9) Mostra i cartelli
10) Consenti inversione ad U al punto di passaggio.
The 8 th voice it's in English.
The problem it's that the voice 8 th it's not translate in Italian; but it's only without translation o without function? I have used the software in English language and I don't understend the difference if this option is on or off: can You help me?
it's not "voices" - it's texts. "menu items" or "text items" or "options" would be better.
If the option is activated (hook in the checkbox) a routing point will be moved to the next usable road - if it is set on a bicycle lane or a blocked road, for example.
You will not set a routing point on a bicycle lane - this function is important, when you import a route from a gpx file.
But this function only works with roads that are marked as "blocked" for motor vehicles in the map data - just tested in Frankfurt am Main, lots of pedestrian ways are not marked as blocked, and i can put routing points there. So you better ignore this function.
The "string not found" error comes from a missing string in the italian language file or a field name error in the database. I could reproduce it.
