I can confirm this.  If I type "VANTAA", the list will suddenly pop up.
For anything up to "VANTA", I see nothing.

In the Edge 705, it's the screen Where To?/Find Places/Addresses, the one
that asks "<Enter Number>", "<Enter Street Name>", and "<Enter City>".
If I enter a "city" (not really a city, see above), the list of "Matches"
on the bottom half of the screen will only show streets within that city.

Alas, the "city names" are not really names of cities, but names of places
within cities.  In Finland, street names are unique within a city.  When
cities are merged (to reduce overhead and to gain synergy in arranging
public services), duplicate street names are eliminated by renaming.

If it is not possible to associate a street with multiple "cities"
(say, Kerava and Ahjo (a part of Kerava)), it'd be useful to have the
streets associated with a city rather than a smaller place.  I don't know
the names of all suburbs or villages (even in my home city), but I know
the names of nearby cities.  I can understand it's easier to associate
each street with the nearest village/town/city POI than to look for
surrounding border polygons.
