Remove Cassette from 99RL w/Navi
 

I have a 99 RL with Navigation. I need to know how to remove the cassette deck (to repair or replace it). It is the original system (built by Alpine I believe). Any ideas? :

why does everyone think Alpine does Acura stuff. Im pretty sure its Bose (JUST LIKE IT SAYS RIGHT ON THE RADIO) IN BIG BOLD LETTERS!!
