Google Map API V3 - How to create a custom dynamic layer and overlay it

Using Google Map API V2 and ArcGIS API for JavaScript, I create a custom dynamic layer and add it to google map as follow:
      var dynamicMap = new esri.arcgis.gmaps.DynamicMapServiceLayer("", null, 0.75, dynmapcallback);

    function dynmapcallback(groundov) {
      //Add groundoverlay to map using gmap.addOverlay()
      dynMapOv = groundov;

I'm migrating the code to use Google Map API V3, but I missing the part to overlay the dynamic services.

Any advise? Is there a way to achieve this?
