Hi,
If you want to find any automatic map (and not manually-created maps) there is an internal function for that:
get_post_meta_map ($postid)
You can find it in file ‘mappress_map.php’.
The only difference between regular maps and automatic is that automatic maps have property ‘metakey’ set to true, so that function reads any maps attached to a post and looks one with ‘metakey’ set.
I hope that helps.
