Quote:
if you go into the street and actually select a street, does that function or cause the same issue?
Yes

Suppose to setting CASTELLETTO SOPRA TICINO, VIA VERNOME (using City/Street method)
The streets box show the correct street
But when you click GO, the route is calculated to drive me ad CASTELLETTO (EMILIA ROMAGNA,BOLOGNA).
Now, suppose to setting 28053, VIA VERNOME (using CAP CODE/Street)
The streets box still to show the correct street.
And this way the route drive me to the correct destination.
bye, bye,
