Hi Charlie,

could you elaborate on that? What tests did you do and with what kind of GPS/software? My experience with the Garmin stuff is that this needn't be the same over the whole model range...

Anyway, I've attached a patch with your range. This one should actually do what it is supposed to do.

What I found out while looking at the source is, that while country and region strings are only saved once and then shared between all entries, the POI entries itself are not shared, even if they are identical. From looking at the file format it should be possible to share the entries. This should save a lot of space if you have a default name for a lot of your POIs that don't have/display address info.
