You will opt for the appearance of the built-in controls if you perform the following step:

  1. Alter the mapOptions object as follows:

    var mapOptions = {
      center: new google.maps.LatLng(43.771094,11.25033),
      zoom: 13,
      mapTypeId: google.maps.MapTypeId.ROADMAP,
      panControl: true,
      scaleControl...
