Google Maps API V3 doesn’t support the V2 GOverviewMapControl option, yet. I’ve come across a piece of code at http://dl.google.com/io/2009/pres/Th_1045_Maps_API_Mobile.pdf , silde 19, that gives the code to display the smaller map, but not the draggable, semi-transparent blue box that you generally see here. It’s possible, but unofrtunately the code is ‘ellided’. Anyone have any ideas how to generate this? Thanks

    Within the overlayMap, add a draggable marker to display the frame of the RectangleOverlay, and a non-draggable marker to display the semi-transparent box itself. Then, add bindings to some of the maps’ events to update size and position of the markers, i.e. the maps’ bounds_changed, drag, and/or center_changed events. Finally, update the location of the maps when the frame is dragged by binding a function to its dragend event.
