Location Marker Not showing

I can't figure out why the location marker is not showing up. Any help would be much appreciated. Thanks.

using UnityEngine; using UnitySlippyMap.Map; using UnitySlippyMap.Layers; using UnitySlippyMap.Markers; using System.IO; using System.Collections; using System.Collections.Generic;

public class TileMap : MonoBehaviour {

private MapBehaviour map;
public Texture MarkerTexture;
public Texture LocationTexture;
private List<LayerBehaviour> layers;

// Use this for initialization
void Start () {

    // create the map singleton
    map = MapBehaviour.Instance;
    map.CurrentCamera = Camera.main;
    map.InputDelegate += UnitySlippyMap.Input.MapInput.BasicTouchAndKeyboard;
    map.CurrentZoom = 16.0f;
    //map.UpdatesCenterWithLocation = true;  NOT WORKING

    // Location
    map.CenterWGS84 = new double[2] { 73.080740, 33.597513 };
    map.UsesLocation = true;
    map.InputsEnabled = true;
    layers = new List<LayerBehaviour>();

    // create an OSM tile layer
    OSMTileLayer osmLayer = map.CreateLayer<OSMTileLayer>("OSM");
    osmLayer.BaseURL = "http://a.tile.openstreetmap.org/";

    layers.Add(osmLayer);

    // create some test 2D markers
    GameObject go = TileBehaviour.CreateTileTemplate(TileBehaviour.AnchorPoint.BottomCenter).gameObject;
    go.GetComponent<Renderer>().material.mainTexture = MarkerTexture;
    go.GetComponent<Renderer>().material.renderQueue = 4001;
    go.transform.localScale = new Vector3(0.5f, 0.5f, 0.5f);
    go.transform.localScale /= 7.0f;
    go.AddComponent<CameraFacingBillboard>().Axis = Vector3.up;

    GameObject markerGO;
    markerGO = Instantiate(go) as GameObject;
    map.CreateMarker<MarkerBehaviour>("test marker 1", new double[2] { 73.080740, 33.597513 }, markerGO);

    markerGO = Instantiate(go) as GameObject;
    map.CreateMarker<MarkerBehaviour>("test marker 2", new double[2] { 73.080860, 33.597933 }, markerGO);

    markerGO = Instantiate(go) as GameObject;
    map.CreateMarker<MarkerBehaviour>("test marker 3", new double[2] { 73.080220, 33.597899 }, markerGO);

    DestroyImmediate(go);

    // create the location marker
    go = TileBehaviour.CreateTileTemplate().gameObject;
    go.GetComponent<Renderer>().material.mainTexture = LocationTexture;
    go.GetComponent<Renderer>().material.renderQueue = 4000;
    go.transform.localScale /= 27.0f;

    markerGO = Instantiate(go) as GameObject;
    map.SetLocationMarker<LocationMarkerBehaviour>(markerGO);

    DestroyImmediate(go);
}

void OnApplicationQuit()
{
    map = null;
}

// Update is called once per frame
void Update () {

}

}
