 From the question below, apparently the D72 (and the D710 according to 
another post) display a G-overlayed diamond symbol regardless of the 
overlay specified by the station, but at least (apparently) the actual 
overlay is displayed to left of the G-diamond.

Is it possible that Kenwood didn't implement the actual specified 
Numbered Diamond graphic, but included the G overlay on their base 
alternate table symbol because it looked good with the old I before it 
(I G, get it?)?  Any way to get this fixed in some future firmware 
upgrade so as not to confuse potential non-IGate use of overlayed 
diamonds?  At least the G would show to the left of the (hopefully 
plain) diamond indicating an old-style Gate?

PS.   Asking the question based on the following post (secondarily 
confirmed) from the APRSISCE Yahoo group.
