But the metabox is the same configuration:

       // GOOGLE MAPS 
    $meta_boxes[] = array (
        'id' => 'location',
        'title' => 'Mapa',
        'post_types' => 'local', //array( 'local' , 'negocio' ), //$post_types,
        'context' => 'after_title',
        'style'   => 'seamless',
        'priority' => 'high',
        // 'geo' => true,
        // Return only cities and business results
        'geo' => array(
                'types' => array( 'establishment' )
        ),
                'storage_type' => 'custom_table',    // Important
                'table'        => 'locales', // Your custom table name
        'fields' => array(
            // Address field.
...
...
            array(
                'id'            => 'mb_mapa_map',
                'name'          => 'Mapa',
                'type'          => 'map',
                //'language'      => 'es',
                // Default location: 'latitude,longitude[,zoom]' (zoom is optional)
                // 'std'           => '-6.233406,-35.049906,15',
                // Address field ID
                'address_field' => 'address_location',
                //'geo' => true,
                'api_key'       => 'AIzaSyCjqt3G7n6brVxxxxxxxxx',
            ),
