Translate GPS Position into transformPosition

Hi,

i am trying to rotate the camera into the direction the map is moving.

When i get a new GPS ping, i'm lerping the map towards that point:
OnlineMaps.instance.position = Vector2.Lerp(fromPosition, toPosition, angle);

this works fine.

Now i want to move a GameObject on the corrsponding position in unity worldspace:

       
        this.unityPosition = OnlineMapsControlBase.instance.GetPosition(toPosition);
        target.position = new Vector3(this.unityPosition.x, 0 , this.unityPosition.y);
        gameObject.transform.LookAt(target);

This really doesnt work properly   any clues how i could properly achieve this?

Thanks!
