Hi Marko,
I can confirm this. If I type "VANTAA", the list will suddenly pop up. For anything up to "VANTA", I see nothing.
Yes, weird isn't it?
As reported by a tester, if you select a city, it doesn't limit the roads in the list to only the roads in that city, you still get presented with a list of all the roads in the known universe.
That's true for the list of street names. However, if you select a city, it will limit the matches on the main "find a street" screen. I tested by searching for "Ratatie" before and after selecting "Ahjo, FIN" (a suburb of the town Kerava).
Err, I don't understand you there. What's the "find a street" screen? Perhaps, the etrex doesn't have that?
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.
I was having a stupid moment, I know what you mean now.
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.
The association of roads with "cities" is being done by Bernhard's code. Perhaps an option that allowed you to specify the minimum size of "city" to use for road addresses could be added? I think it would have to take distance into account because if you just suppressed using a village name without considering distance, you would end up with the silly result of a road 1KM from a village being associated with a town, say, 20KM away. Cheers, Mark
