I couldn't get any of the various simple suggestions around the web to work for embedding a google map link in an iframe.
I ended up using the google map API script instead of an iframe, generating the initial code by filling in the boxes at:
[View:http://www.map-embed.com/:750:50]
and modifying the resultant code to suit my purposes.
You could use the link above to gen the code for your own map, and then optionally use my code with the longitude and latitude produced by the above web site copied into my code. You can also insert your own html into "content" below, independent of what the above website produces.
<?php
// IE won't work with percentage height and FF won't work with em units.
// Simple code here assumes if browser isn't IE, then is FF;
// And I don't care about other browsers.
//
$height = "$browser" == 'ie' ? '25em' : '99%' ;
$width = "$browser" == 'ie' ? '99%' : '99%' ;
