UnityでGPS使ってストリートビューを歩きたい

GPSLoader.cs

			yield break;
		}
		Input.location.Start();
		int maxWait =  120;
		while (Input.location.status == LocationServiceStatus.Initializing && maxWait > 0) {
			yield return new WaitForSeconds(1);
			maxWait--;
		}
		if (maxWait < 1) {
			label.text = "Timed out";
			yield break;
		}

			label.text = "Unable to determine device location";
			yield break;
		} else {

			string s = "Location: " +
