However, as the layers are enabled by default, the map looks too
crowded as its zoomed out all the way when first viewed.

Looking at the public Google Maps page, there is a More button that
allows visitors to select these layers which is much more friendly.

To get the layers working, I had to change my map API from v2 to v2.x
but the MORE button doesn't show.

How do we enable this? I have the Map, Satellite and Terrain options
displaying, just need the More button...

Thanks again,

Here's a section of my code so far:

function load() {

        var myPano = new
GStreetviewPanorama(document.getElementById("pano"));
        var map = new GMap2(document.getElementById("map"));
        map.addControl(new GLargeMapControl());
        map.addControl(new GHierarchicalMapTypeControl());
        map.addControl(new GOverviewMapControl());
        map.addControl(new GScaleControl());
                map.enableGoogleBar();
                map.enableScrollWheelZoom();
        map.setCenter(new GLatLng(41.902277,-48.867187), 2,
G_NORMAL_MAP);
                map.addMapType(G_PHYSICAL_MAP);

                // Add Panoramio and Wikipedia options.

                map.addOverlay(new GLayer("com.panoramio.all"));
        map.addOverlay(new GLayer("org.wikipedia.en"));

                // Add streetmap overlay and show the street when available.

                svOverlay = new GStreetviewOverlay();
                map.addOverlay(svOverlay);
                GEvent.addListener(map,"click", function(overlay,latlng) {
                  myPano.setLocationAndPOV(latlng);
                });

                // Show a pop with coordinates when someone clicks on the map.

                GEvent.addListener(map, 'click', function(overlay, point) {
        var latLngStr = "<div><h5>You clicked on the map! <br />Copy/
paste the following numbers into your profile settings <br />to put a
marker at this exact spot!<br /><br />Lat = " + point.y + "<br />Long
= " + point.x + "<br />Only enter the numbers, don't include any
letters!</h5></div>";
                map.openInfoWindow(point, latLngStr);

        });

        // Download the data in data.xml and load it onto the map.

        GDownloadUrl("http://millennium-thisiswhoweare.net/tiwwa/
membermap_xml/data.xml",function(data) {
          var xml = GXml.parse(data);
          var markers = xml.documentElement.getElementsByTagName("marker");
          for (var i = 0; i < markers.length; i++) {
                var point = new GLatLng(parseFloat(markers[i].getAttribute("lat")),
                                                parseFloat(markers[i].getAttribute("lng")));

                var displayname = markers[i].getAttribute("displayname");
        var title = markers[i].getAttribute("title");
        var posts = markers[i].getAttribute("posts");
                var msg = markers[i].getAttribute("msgtotal");
                var views = markers[i].getAttribute("profileviews");
                var topics = markers[i].getAttribute("topics");
                var type = markers[i].getAttribute("type");
                var userid = markers[i].getAttribute("userid");
        var html = "<div><h5>" + displayname + "<br />" + title + "</
h5><div id=\"profile_link\"><a href=\"/tiwwa/index.php?showuser=" +
userid + "\" title=\"View " + displayname + "'s full social profile

                var html= html;

          // create the marker
                var marker = createMarker(point,displayname,type,html);
                map.addOverlay(marker);          }
          // put the assembled sidebar_html contents into the sidebar div
          document.getElementById("sidebar").innerHTML = sidebar_html;
