Show all nodes in the Getlocations map with diffrent marker colors per Content Type?
There is a bug in getlocations.views.inc line 96 &amp; 97:

if (isset($options['node_marker__' . $location['type'] . '__' . $location['field_name']])) {
              $marker = $options['node_marker__' . $location['type'] . '__' . $location['field_name']];


You need to strtolower $location['type'], then it works:

if (isset($options['node_marker__' . strtolower($location['type']) . '__' . $location['field_name']])) {
              $marker = $options['node_marker__' . strtolower($location['type']) . '__' . $location['field_name']];
