I have recently noticed that polygons assigned codes of the type 0x101xx are not displayed on my Garmin 62s.  However, if I open the compiled maps in a package such as GPSMapEdit I can see that the features are indeed compiled correctly in the maps.

I am using version r1973
The polygons are correctly defined in a TYP file
If I redefine the polygons to alternative unused codes of type 0x2x or 0x3x and also change the code in the TYP file then the polygons are displayed correctly.

It does not seem to matter what the Drawing Level is in the TYP file.  Non of the 0x101xx types are ever displayed.

In the case of Polylines, I have used several codes of the types 0x100xx, 0x101xx and 0x105xx and they are displayed correctly.

I am really puzzled by this and would really appreciate any insight into what is happening.

At the lower drawing levels in the TYP file I have the following defined:

Type 0x4b [Background (coverage)], Drawing order: 1

Type 0x32 [Sea], Drawing order: 2 (Placeholder only)

Type 0x27 [?], Drawing order: 3 (Placeholder only)

Then follows Drawing Level 4 with codes 0x02, 0x03 etc.

Any ideas on this please?.
