How to use Locationinfo in unity.

I need to know how to use Latitude & Longitude of our device. When i tried to display the geographical location of my device with Locationinfo in unity, it shows nothing. Actually i want to load OSM (Open Street Map) from a url to an Image Plane in unity. So in url i need to pass the location of the device so that in application the map of the current area of that device can be shown.

Any idea how to get the location of a device in unity??
