The UIview addon only displays it as a comment field to a standard 
posit.   The signpost symbol is a fixed static image with no overlays in 
the UIview symbol set.  I would guess because the APRS spec doesn't make 
it clear that this is supposed to be a dynamically-alterable symbol.   I 
recall puzzling over this symbol at the time I first started updating 
the symbol set.

Ditto for APRSplus.  

It doesn't show at all in APRSpoint.   (Any posit with this symbol, or 
any other missing from the SEVERELY truncated APRSpoint symbol set,  
shows up as  the generic Microsoft MapPoint pushpin symbol.)
