Straßenanbindung mit google maps apex

[patruf]

Was muss ich denn in meinem Javascript verändern um ne straßenanbindung zu erstellen?

mein Javascript:

//<![CDATA[

//globals

var bounds = new GLatLngBounds();

function initMap() {

if (GBrowserIsCompatible()) {

var map = new GMap2(document.getElementById(„map“));

var title = „&amp:stuck_out_tongue_winking_eye:2_CUST_STREET_ADDRESS1.“;

map.addControl(new GSmallMapControl());

map.addControl(new GMapTypeControl());

var point = new GLatLng(&amp:stuck_out_tongue_winking_eye:1_LOCATION.);

var point = new GLatLng($v(‚P2_LATITUDE‘),$v(‚P2_LONGTITUDE‘));

bounds.extend(point);

map.setCenter(point);

map.setZoom(map.getBoundsZoomLevel(bounds)-4);

var marker = new GMarker(point);

map.addOverlay(marker);

marker.openInfoWindowHtml(’<div class=„tiny“>’ +
title.replace(/~/g,"<br />") + ‚</div>‘);

}

}

//]]>

var map;
var directionsPanel;
var directions;

function initialize() {
map = new GMap2(document.getElementById(„map_canvas“));
map.setCenter(new GLatLng(42.351505,-71.094455), 15);
directionsPanel = document.getElementById(„route“);
directions = new GDirections(map, directionsPanel);
directions.load(„from: 500 Memorial Drive, Cambridge, MA to: 4 Yawkey Way, Boston, MA 02215 (Fenway Park)“);
}
