Albrecht, You can use the osm generic (default) type file from garmin.openstreetmap.nl: https://github.com/ligfietser/mkgmap-style-sheets/tree/master/typ/osm%20gene... Not sure if the Island polygon (0x53) from this typ file is wrong, too.

AKAIK these problems can only be solved with a typ file that specifies the draw order for the polygon types.
Hmmm, yes, that makes sense. Do you know where I can find a default TYP file (source) which I could modify?
Or maybe using a different type for the island relation would help.
Looking at this list <http://wiki.openstreetmap.org/wiki/GroundTruth_Standard_Garmin_Types#Standard_Garmin_Types>, I wonder if there is something more appropriate.... :-/
Thanks, Albrecht.
