[Google Maps API v3] Toggle and restrict map to custom tiles

[Tom R.]

Hello All-

I found no clear mention of this on the forum so far.  I'm able to
display my custom tiles using the following portions of JS code:

// ...etc
customlayer = map.overlayMapTypes.insertAt(0, new
google.maps.ImageMapType({
      getTileUrl: function(coord,zoom) {
        var baseURL = 'maptiles/';
        baseURL += 'preciprelief/' + zoom + '/' + coord.x + '/' +
(Math.pow(2,zoom)-coord.y-1) + ".png";
        return baseURL;
      },
      tileSize: new google.maps.Size(256, 256),
      isPng: true,
      minZoom: 7,
      maxZoom: 12
      })
    )

//...etc
customlayer.setMap(map);

But how do I toggle between the default Google road map and my
customer tiles so that only mine are visible?  Or, in other words, how
do I turn off the Google tiles, perhaps using a variable linked to a
custom drop-down menu?

Thanks in advance.  I hope this helps someone else in the future.

Cheers
Tom
