wp_nav_menu Home Link

I’m trying to remove the link to the home page in my wp_nav_menu but it’s not working. The him page is a static page I set in the preferences. I found this but it doesn’t seem to work so I’m obviously doing something wrong. Is there a better way to do this?

This is my functions.php:

register_nav_menus(array('primary' => 'Primary Navigation'));

	/* Remove Home Page Link */

	function mytheme_nav_menu_args( $args ) {
	    $args['show_home'] = false;
	    return $args;
	}
	add_filter( 'wp_nav_menu_args', 'mytheme_nav_menu_args' );

This is in my header:

<?php wp_nav_menu( array( 'echo' => true , 'theme_location' => 'Primary Menu' , 'depth' => '1' ) ); ?>
