Pixel to LatLng Google Maps API v3

Im sure you are like me and not interested in the reason why v3 has made a simple function such as fromContainerPixelToLatLng so complicated, however here is how I got it working.

In my working example I have created a div that hangs over the map div. When a user clicks and Drags the over-layed div the marker moves to the LatLng Coordinates of the map.

var myOptions = {
    zoom: 2,
    center: new google.maps.LatLng(25,25),
    mapTypeId: google.maps.MapTypeId.ROADMAP
var map = new google.maps.Map(

var overlay = new google.maps.OverlayView();
overlay.draw = function() {};

And now the magical function used in our click event for an object that is over-layed on-top of our maps. (Given that we are changing the position of a marker defined as `start_marker)

var coordinates = overlay.getProjection().fromContainerPixelToLatLng(
    new google.maps.Point(92, 61)

console.log(coordinates.lat + ", " + coordinates.lng);

Note the variables 92 and 61 are the left and top values of our map div.

getProjection() only works after overlay.onAdd is invoked.
