Seeing as the developer hasn't been online since 2008, I'll post how I do Google maps...

AdminCP > Custom BB Codes > Add New BB Code

Title: Google Maps
BB Code Tag Name: map
Replacement:

<div align="center" style="margin: 5px 5px 5px 5px;">
<table class="tborder" cellpadding="6" cellspacing="1" border="0" width="100%">
<tr>
<td class="thead" style="text-align:center"><iframe width="100%" height="600" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="http://maps.google.com/maps?q={param}&ie=UTF8&hq={param}&t=h&output=embed"></iframe></td>
</tr>
</table>
</div>

Use {option}: No
Remove Tag If Empty: Yes
Disable BB Code Within This BB Code: Yes
Disable Smilies Within This BB Code : Yes
Disable Word Wrapping Within This BB Code: Yes
Disable Automatic Link Parsing Within This BB Code: Yes

Use would be:
[map]Sacramento, CA[/map]
[map]Sacramento, CA to San Diego, CA[/map]
[map]pig trail harley davidson[/map]

It works great for us. I also did a [chatmap] version that limits the size to 200px for use in the chatbox.

You can add "&iwloc=near" to the end of the src= code to disable the name bubble in the map. This is very helpful in my [chatmap] version due to its smaller iframe size.
