 var latitude = position.coords.latitude;                    //users current
 var longitude = position.coords.longitude;                 //location
 var coords = new google.maps.LatLng(latitude, longitude); //Creates variable for map coordinates
 var directionsService = new google.maps.DirectionsService();
 var directionsDisplay = new google.maps.DirectionsRenderer();
 var mapOptions = //Sets map options
 {
   zoom: 15,  //Sets zoom level (0-21)
   center: coords, //zoom in on users location
   mapTypeControl: true, //allows you to select map type eg. map or satellite
   navigationControlOptions:
   {
     style: google.maps.NavigationControlStyle.SMALL //sets map controls size eg. zoom
   },
   mapTypeId: google.maps.MapTypeId.ROADMAP //sets type of map Options:ROADMAP, SATELLITE, HYBRID, TERRIAN
 };
 map = new google.maps.Map( /*creates Map variable*/ document.getElementById("map"),    mapOptions /*Creates a new map using the passed optional parameters in the mapOptions parameter.*/);
 directionsDisplay.setMap(map);
 directionsDisplay.setPanel(document.getElementById('panel'));
 var request = {
   origin: coords,
   destination: 'BT42 1FL',
   travelMode: google.maps.DirectionsTravelMode.DRIVING
 };

 directionsService.route(request, function (response, status) {
   if (status == google.maps.DirectionsStatus.OK) {
     directionsDisplay.setDirections(response);
   }
 });
 });
