Hi!

I agree. The areas on the Garmin should be drawn by the drawing priority 
defined in the type file, completely disregarding any layer tags. With 
proper multipolygons, everything should look good. But if you start 
changing around drawing priorities to get lakes on top of wood, then 
probably some wooded islands in lakes will disappear where somebody 
thought wood needs to go on top of water.

Adding proper multipolygons to the data instead of relying on any 
drawing order is the only useful solution.
