Looking for a on-screen compass in Unity 4

I am trying to create a on-screen compass that will point the direct the player is moving. I am using a 3rd person controller with a camera attached and following. I found a couple that is from a 1st person perspective but not from a 3rd person.

 

could you not make the rotation of the compass needle the same as rotation of the player in the world coordinates..for instance transform.rotation.y

 

There's an excellent (and cheap, $25) map system on the asset store - providing the "compas" out of the box, be sure to check it out: KGFMapSystem.
