I am struggling with geo-calibration of orienteering maps to be used in Garmin 66st. The basic maps were made georeferenced. Most often the KMZ-files do not work. What is the best map parameters.

I use OKmap with 3-5 georeference points. The coordinates I find in Google Earth.

EARLIER RECOMMENDATION
I have earlier been recommended
Area ETRS89 / KP89 Zealand / UTM zone N32

GOOGLE EARTH
I aligned a map in Google Earth. Google saved it as
Datum: 6326 - World Geodetic System 1984 ensemble
Prime meridian: 8901 - Greenwich (0°)
Ellipsoid: 7030 - WGS 84
Unit of measure: 9001 - m
Map projection
CRS: 3857 - WGS 84 / Pseudo-Mercator
Map projection: 1024 - Popular Visualisation Pseudo Mercator

I HAVE MADE A WORKABLE FILE IN OKMAP WITH
One pojection which made a workable Gramin KMZ file is
Datum: 6258 - European Terrestrial Reference System 1989 ensemble
Prime meridian: 8901 - Greenwich (0°)
Ellipsoid: 7019 - GRS 1980
Unit of measure: 9001 - m
Map projection
CRS: 2197 - ETRS89 / Kp2000 Zealand
Map projection: 9807 - Transverse Mercator

I am ignorant and do not understand the settings. I just want a setting so I can georeference a map in OKmap.

Hi Ivar,
please send me the entire map at info@okmap.org.
I'll try to do a calibration that works well and generates a good KMZ.
Are you sure that the correct projection is CRS 2197?
