Hi Marko,

The mysteries of the zoom-behaviour of default Garmin objects is a  
scary subject.  :)

The 0x64 series are man made geographical POIs.  I think Garmin  
intends this series to be used for navigational purposes (i.e. there's  
a huge building/dam/oil field over there, I'll use it to triangulate  
my location).  This is probably why they appear even when zoomed out.

I think you're starting to push the limits of what is practical using  
the default Garmin objects (i.e. without the use of a TYP file) and a  
default style that is suitable for all uses (hiking, cycling, driving,  
tourism etc).

Have you tried one of the "out-of-bounds" codes around the 0x2b area?   
Maybe 0x2b06 or 0x2b07 (tent icon) or 0x2b08 to 0x2b1f (green/white  
bed)?
