Split: "Get Directions" button to Open Google Maps Link

ok i did some testing with the coding and i found the problem

on the basic get location button it seems to only go to the location of the latest added listing

the button from this addon works good if you use the first one with only the coordinates

if you add the name, and the name does not exist in google maps then it wont work
it will not go to the coordinates

only things that google can find will work

like address for example

function geodirectory_detail_page_google_map_link() {
    global $post, $preview;

    if ( !$preview && !empty( $post->post_latitude ) && !empty( $post->post_longitude ) ) {
		
	        if (isset($post->post_address) && $post->post_address) {
                    $sd_address .= $post->post_address;
                }
		
                if (isset($post->post_city) && $post->post_city) {
                    $sd_address .= '+ ' . $post->post_city;
                }
                if (isset($post->post_region) && $post->post_region) {
                    $sd_address .= '+ ' . $post->post_region;
                }
                if (isset($post->post_country) && $post->post_country) {
                    $sd_address .= '+ ' . $post->post_country;
				}					
		
		
        $maps_url = add_query_arg( array(
                        'q' => $sd_address,
                        'sll' => $post->post_latitude . ',' . $post->post_longitude,
                    ), 'http://maps.google.com/' );
					
					

i found out that it only gives wrong direction in the netherlands
my listings in other countries work good

atm im checking if i can find any difrence between the netherland listings and for example spain

i will find it

if it works in spain then it should also work in the netherlands

last week i also had something like this
then it did not show any listings in the map
reason was that one of the listings had 52.783.070 in coordinates in stead of 52.783070
the extra point made it not work for the complete map

im hoping its something like this again
