Hi Mark,

thanks for testing.

Yes I can reproduce your problem with my UK test case. I think I found a 
solution without messing up the results in countries with geodb tagging. 
The reason behind this problem is that I would like to use only real 
city names in poi addresses. I don't want to use suburbs or hamlet names 
for this purpose. In countries with poor is_in tagging this went wrong 
and all places which I don't have any info about where not used for the 
poi addresses. I think now it should work for both cases ...

I think we should really discuss how OSM tagging could be improved to 
make generation of reliable address information easier. The current 
is_in tag is really hard to handle and. I have detected so many 
variations. I would prefer the separated tags version like 
is_in:country, is_in:region, is_in:city.

Anyway the incremental patch for the poi branch is attached and also 
adds US support to the LocatorConfig.xml file. Any contributions to the 
LocatorConfig.xml file are welcome. To do so you have look at some of 
your is_in tags. A simple "grep is_in my.osm | sort -u" should do it to 
get a quick overview.

<country name="Deutschland" abr="DEU" geodb="1" regionOffset="3" 
poiDispFlag="0xc">
        <variant>Bundesrepublik Deutschland</variant>
        <variant>Germany</variant>
        <variant>DE</variant>       
</country>

name -> specifies the country name you want to see on the garmin.
abr -> the abbreviation  for this country used on the garmin
geodb -> 1 for Germany, Austria, Swizterland that has imported data from 
geodb. Default is 0
regionOffset -> Which administrative level down from the country name 
should be used as region info. Default is 1.
poiDispFlag -> Address display format: Default is 0 / 0xc show street 
before street number / show zip before city
variant -> This are the different spellings of this country in the is_in 
tags you would expect

Thanks
Berni.
