1. You have a typo in «Input.location».
2. You do not check the status.

3. The best way to do this:

this my code

OnlineMapsMarker3DInstance playerMarkerInstance;
void Update(){
playerMarkerInstance.marker.position = new Vector2(Input.loaction.lastData.longitude ,Input.loaction.latitude);
}

As I work well under the updated version it does not work.
