cd deck removal

Hey I just got a new cd deck and was wondering how I get the old aftermarket one off. It is a sony c66o and I believe it needs a key to get out cause it has no screws to take out.

your gonna have to take off ur whole center console (the plastic between the seats) there screws and shit... just look and start unscrewin

there is latch on either side, you have to play with them a little ...... or see if your dealer has a pair of keys you can borrow
