Hi, just in case someone is still stuck.
I didn’t want to edit the plugin files so I found the following solution:
<script>
$(window).load(function (){
var mapStyles = [{ "stylers": [{ "hue": '#ff0000'}, { "lightness": -1} ]}];
loaded_map = window.cslmap.gmap;
loaded_map.setOptions({ styles:mapStyles});
});
</script>
You can also set the opacity of the map container to 0 and fadeTo 1 after the styles are applied.
