[mkgmap-dev] POI without name

Hi Thorsten,

do you see that behaviour also with original Garmin maps?
Maybe the device ignores the index if it detects errors in it.

I can only say for the GPSMap 6x series (at least for the three devices
I own):
Old firmwares use the index for POI search. It is quick and you only
see what is in the index.
New firmwares seems to lookup POI directly in the tiles and not use the
Index at all. Even if the device is newer and faster than the old one,
searching POIs with this can take a really long time ...
And in my experiements, all POI will be shown in the index, independent
of the number. At least I haven't found any which is not shown. With
the old firmware, a lot of numbers are not shown in the list.
