Mapstraction - Jun 2010 - crosshair with v2

Hi,

I''m moving to V2. I used to create a crosshair at the center of my map 
in v1.
It doesn''t work in v2.

Can somebody point me to the good way to do this.

In v1, I used :

 function addcross() {
 Mapstraction.prototype.removeCrosshairs=function(cross)
 {
  var map=this.maps[this.api];
  var container=map.getContainer();
  container.removeChild(crossh);
 };
 Mapstraction.prototype.addCrosshairs=function(Cross)
 {
  var map=this.maps[this.api];
  var container=map.getContainer();
  var crosshairs=document.createElement("img");
  crosshairs.src=Cross;
  crosshairs.style.border=''0'';
  crosshairs.style.position=''fixed'';
  crosshairs.style.zIndex=''500'';
  container.appendChild(crosshairs);
  this.crosshairs=crosshairs;
  return crosshairs;
 };
 }

The problem is map.getContainer doesn''t exist anymore.
I use googlev3 and openlayers.

What is the best way to have this working in v2 ?
