Did you add the following code to one of your template files?

<?php

    pronamic_google_maps(array(
        'width' => 290 ,
        'height' => 200
    ));

    ?>

You should add the code above to one of the following files within the loop.

* single.php
If you want to show the map on a single post page.
* page.php
If you want to show the map on a page.
* loop.php
If you want to show the map on the posts overview page.

The good place to add the code is right after the <?php the_content(); ?> code.
