Horizontal scrolling style compass

I've seen a few requests for this and the other day came across a code snippet that gave me an idea on how to add this to my game. The result is below. There's probably a more efficient way to get some of that out of OnGUI(), if I find it or see suggestions for improvement I'll update this:

 /// <summary>
 /// Simple horizontal style compass for 3D world
 /// Attach this to your Player. 0 degrees is North. 
 /// Adjust if your orientation is different by changing the letters.
 /// Use/modify anyway you like.
 /// </summary>
 
 using UnityEngine;
 using System.Collections;
 
 public class QM_Compass : MonoBehaviour {
     
     // Feel free to set these all to private once you are done tweaking:
     private Transform myTransform;
     public int facingDir;
     public int degreeOffset;
 
     void Start () {
         myTransform = transform;
     }
     
     // Minor adjustments from 0,90,180,270 due to Font width
     // Adjust letter offset to match your Font size/width
     
     void OnGUI() {
         
         if(degreeOffset > -85 && degreeOffset < 90) {
             GUI.Label( new Rect((Screen.width/2)-degreeOffset*2,
             (Screen.height)-50,
             180,
             25),
             "N");
         }
         
         if(degreeOffset > 5 && degreeOffset < 180) {
             GUI.Label( new Rect((Screen.width/2)-degreeOffset*2+180,
             (Screen.height)-50,
             180,
             25),
             "E");
         }    
         
         if((facingDir > 95 && degreeOffset> 95) || (facingDir < 276 && degreeOffset < -90)) {
             GUI.Label( new Rect((Screen.width/2)-facingDir*2+360,
             (Screen.height)-50,
             180,
             25),

         }
         
         if((facingDir > 186 && degreeOffset < -5)) {
             GUI.Label( new Rect((Screen.width/2)-facingDir*2+540,
             (Screen.height)-50,
             180,
             25),
             "W");
         }
         
         GUI.Box( new Rect((Screen.width/2)-180,
             (Screen.height)-65,

         facingDir = (int)Mathf.Abs(myTransform.eulerAngles.y);
         if (facingDir > 360) facingDir = facingDir % 360;
                 
         degreeOffset = facingDir;
         
         if(degreeOffset > 180) degreeOffset = degreeOffset - 360;
