This code will hide ALL the navigation on your Myspace page.

Paste this code anywhere in your edit profile section:
<style type="text/css">body div table tbody tr td font {visibility:hidden;} body table div table tbody tr td font {visibility:visible;} table td div div font {visibility:hidden;} tr {background:transparent;} body table div font a, body table div div {visibility:hidden;} body table table div font a, body table table div div {visibility:visible;}</style>

Or if you want to also hide the Copyright at the bottom, use this code:
<style type="text/css">body div table tbody tr td font {visibility:hidden;} body table div table tbody tr td font {visibility:visible;} table td div div font {visibility:hidden;} tr {background:transparent;} body table div font a, body table div div {visibility:hidden;} body table table div font a, body table table div div {visibility:visible;} table div font a, table div div {visibility:hidden; display:none;border:0px!important;background-color:transparent;} </style>
