Removing all controls from a google map

Have you tried this:

http://code.google.com/apis/maps/documentation/javascript/controls.html#DisablingDefaults

function initialize() {
  var myOptions = {
    zoom: 4,
    center: new google.maps.LatLng(-33, 151),
    disableDefaultUI: true,
    mapTypeId: google.maps.MapTypeId.ROADMAP  
  }
  var map = new google.maps.Map(document.getElementById("map_canvas"),
       myOptions);
}

You may see this: google map api by w3schools

As you see in the link, this disables all controls:

var mapOptions = {disableDefaultUI: true}

and the bellow is the options to make them enabled or disabled.

var mapOptions = {
  panControl: true,
  zoomControl: true,
  mapTypeControl: true,
  scaleControl: true,
  streetViewControl: true,
  overviewMapControl: true,
  rotateControl: true
}
