I enabled the three API's at Google:
Google Maps JavaScript API
Google Maps Geocoding API
Google Static Maps API
I get a static map OK. All I get with the dynamic map is a "Loading Map...".
My code:
{% for entry in craft.entries.section('groups').limit(5).find() %}
<li><a href="{{ entry.url }}">{{ entry.title }} , {{ entry.address }}, {{ craft.smartMap.map(entry.address) }}</a></li>
{% endfor %}
