I dont know if I understood you right but here goes nothing...
Best solution in my opinion is to separate the navigation from the pages.
Make a file named navbar.php (or .htm if its only html). Put the links and stuff in it. Then in every page you need the navigation bar, include it to the page.
<html>
<body>
<?php include('navbar.php'); ?>
...
...
And when you change the navigation and upload it to the server, the changes can be seen in every page with only one modification to navbar.php.
