Define formatter in node.tpl.php

Hi everybody,

I've been trying to display the location field with an embedded map (provided by GMap ) in my custom node-xxx.tpl.php.

To do this, I've been looking for the formatter associated to this and tried the following :

$content['field_geolocalisation']['#formatter']="location_all";
print render($content['field_geolocalisation']);

However, there do not seem to be any difference with the default formatter, so am I missing something?

Thank you very much !
