[mkgmap-dev] Error in index

Hi Thorsten,

yes, I remember those problems, but I think I've never seen them on my Oregon 600. Maybe I'll experiment with the number of tiles to find out if there is a threshold value for
a single POI type. My style is close to Minkos "Openfietsmap lite" and uses 0x2a00 for all kinds of restaurants, ignoring cuisine. Maybe that is not a good idea.

Yes, very old problem, and I think already discussed on this list
without resolution.

Depending on the count of POIs, sometimes parts of them are not
findable in the Index, while they are visible on the map.
The number of the POI doesn't matter, it looks more like the number
of POI.

That POI searches take very long is a change in the Garmin firmware.
With my map on a GPSmap 60CSx, searching for POI is really quick and
only the one from the Index are found.
With the same map on my GPSmap 62, the index is ignored and the POIs
are extracted from the map. This takes a long time.
