Change icon on google maps

[airhaul]

I made some route maps for different airlines with google maps...

That wasnt too bad

But stuck trying to change google icons to textual icons like with airport codes i.e KATL

Tried installing mapiconmaker but cant get it to work

Its using Gmap instead of google maps in javascript code. Think I have V3 api installed but everytime try to load even 1 icon simple example just get a grayed out map..

Or if you know a simplier way to add text to google icons would apprecitate.

Dont want to make custom icons but have code enter the airport codes when going through the schedules

Thanks for any help in the right direction

<script type="text/javascript" src="[url=".../mapiconmaker.js"[/url]"></script>
<script type="text/javascript">

var map = new GMap2(document.getElementById("map"));
map.setCenter(new GLatLng(37.441944, -122.141944), 13);
var newIcon = MapIconMaker.createFlatIcon({width: 64, height: 64, primaryColor: "#00ff00"});
var marker = new GMarker(map.getCenter(), {icon: newIcon});
map.addOverlay(marker);
</script>
<div id="map" style="width: 500px; height: 300px"></div>

There is the simple example trying to get to load but keep getting gray map
