Thanks, just did a hack to the plug in... wish it was an option to add a link or not but this will work for what I need to do.
Added to core.php:
$placemarks[] = array(
'title' => $pp->post_title,
'latitude' => get_post_meta( $pp->ID, self::PREFIX . 'latitude', true ),
'longitude' => get_post_meta( $pp->ID, self::PREFIX . 'longitude', true ),
'details' => nl2br( $pp->post_content ),
'permalink' => get_permalink( $pp->ID ),
'icon' => is_array($icon) ? $icon[0] : plugins_url( 'images/default-marker.png', __FILE__ ),
'zIndex' => get_post_meta( $pp->ID, self::PREFIX . 'zIndex', true ),
);
Then you can pull it back out in the functions.js with:
line 116:
createMarker : function( map, title, permalink, latitude, longitude, details, icon, zIndex )
line 101:
bgmp.createMarker( map, bgmpData.markers[m]['title'], bgmpData.markers[m]['permalink'], parseFloat( bgmpData.markers[m]['latitude'] ), parseFloat( bgmpData.markers[m]['longitude'] ), bgmpData.markers[m]['details'], bgmpData.markers[m]['icon'], parseInt( bgmpData.markers[m]['zIndex'] ) );
I'm using it on a rel then with jQuery so I have in line 147:
infowindowcontent = '<div class="bgmp_placemark" rel="'+ permalink +'"> <h1>'+ title +'</h1> <div>'+ details +'</div> </div>';
