Zoom factor Error: <= 500 tiles

[elorigoni]

I'm trying to export for a gpsmap64s. It allow 500tiles custom map.
when I'm trying to export I get the warning:
"The number of tiles is likely to exceed Garmins limit of 100 tiles! Not all tiles will be displayed on your GPS unit. Consider reducing your map size (extend or zoom-factor)."

if the tiles number for <=100 is 14, I have to chose 10 tiles for have no problem kmz.
