Hi,
I updated the extension to use the Google Maps Api v3.
It's easy, you have to override the file : /templates/content/datatype/view/ezgmaplocation.tpl and change the begining.

Replace :

{run-once}


<script src="http://maps.google.com/maps?file=api&amp;v=2&amp;key={ezini('SiteSettings','GMapsKey')}" type="text/javascript"></script>


<script type="text/javascript">


{literal}


function eZGmapLocation_MapView( attributeId, latitude, longitude )


{


   if (GBrowserIsCompatible()) 

   {


       if( latitude && longitude )


           var startPoint = new GLatLng( latitude, longitude ), zoom = 13;


       else


           var startPoint = new GLatLng( 0, 0 ), zoom = 0;


 

       var map = new GMap2( document.getElementById( 'ezgml-map-' + attributeId ) );


       map.addControl( new GSmallMapControl() );


       map.setCenter( startPoint, zoom );


       map.addOverlay( new GMarker(startPoint) );


   }


}


{/literal}


</script>


{/run-once}

By :

{run-once}


<script type="text/javascript" src="http://maps.google.com/maps/api/j...ensor=false"></script>


<script type="text/javascript">


{literal}


function eZGmapLocation_MapView( attributeId, latitude, longitude )


{


       

       if( latitude && longitude ){


               var latlng = new google.maps.LatLng(latitude,longitude);


                    

                } else {


                        var latlng = new google.maps.LatLng(0,0);


                }


                


                var myOptions = {


                     zoom: 12,


                     center: latlng,


                     mapTypeId: google.maps.MapTypeId.ROADMAP


                   };


                    

           map = new google.maps.Map(document.getElementById( 'ezgml-map-' + attributeId ), myOptions);


                

            var marker = new google.maps.Marker({


                     position: latlng


                 });


                  

                 // To add the marker to the map, call setMap();


                 marker.setMap(map);


    

}


{/literal}


</script>


{/run-once}

You no longer need the API key !
