I'm using google maps under my google account to load a kmz file which is good and working, but I want to load a new pin marker by manipulating the header url. So far I've tried q=lat,long which loads the marker, but it doesn't maintain the kmz polygons and info. It simply loads a green arrow (my coordinates) but does so on the plain grey google map.
Does anyone have any idea how to load the marker but still keep the kmz data on the page?
