Hmm.. I don't know.. I did not set the overlay position.. I just added it to
my mapView and mine shows up. Try working with your location settings. I am
not sure why the Location is needed tho. I use an ItemizedOverlay for a list
of items I pull down from a server, which works fine. My map then responds
to a click on an item, and puts another overlay above it with text.
