How to rotation a marker Google Maps API?

Question

I'm new using the API Google Maps tool and I'm trying to make an image of car trip around the map, but I can not make that rotation, the parameter rotation only works when I use an own marcagor tool but when put the image in "url: imagen.png" no achievement that this move, then put the different codes that I have tried to use based on what I've found and until now none work I wish I could support please. Thanks and regards.

     1.- 
     var image = {
     url: 'camion.png',
     rotation:22, //Doesn't work
     origin: new google.maps.Point(0, 0),
     anchor: new google.maps.Point(0, 0),
      };

      for (var i = 0; i < camiones.length; i++) {
      var camionT = camiones[i];
      marker = new google.maps.Marker({
      position: {lat: camionT[1], lng: camionT[2]},
      map: map,
      icon: image,
      shape: shape,
      title: camionT[0],
      zIndex: camionT[3],
      rotation:23
  });
