Google map coordinates info window on click

Question

Does anyone know how make the default Google map interface display long and lat coordinates in an info window when the user clicks on the map?

Header code:

<script src="http://maps.google.com/maps?file=api&amp;v=2&amp;sensor=true&amp;key=..." type="text/javascript"></script>
<script type="text/javascript">
function initialize() {
  if (GBrowserIsCompatible()) {
    var map = new GMap2(document.getElementById("map"));
    map.setCenter(new GLatLng(13.175771, -59.556885), 10);
    map.setUIToDefault();
  }
}
</script>

Body code:

<div id="map" style="width: 640px; height: 300px"></div>

 google.maps.event.addListener(map, 'click', function(event) {
    new google.maps.InfoWindow({
      position: event.latLng,
      content: event.latLng.toString() 
    }).open(map);
 });
