ok, solved.
just copy the nav
<nav id="access">
<a class="nav-show" href="#access">Show Navigation</a>
<a class="nav-hide" href="#nogo">Hide Navigation</a>
<?php wp_nav_menu( array( 'theme_location' => 'primary_nav' ) ); ?>
<div class="clear"></div>
</nav><!-- #access --><code>in page.php right before</code><?php get_footer(); ?>
