This should get you started:

<script type="text/javascript">

function Reload () {
var f = document.getElementById('nav');
f.src = f.src;
}

</script>

'nav' in this case being the name of the iframe you want to refresh, although I am not certain if this is the exact name of the iframe, you will have to double check.

Then you need to initiate the code, you will have to setup code that will process it once your hack is installed. But this code below will allow you to perform the action via link:

<input type="button" value="Reload" onclick="Reload();">
