how to remove factory deck in an 01 ?

just need to know whether theres screws or does the trim just pop off to get to the deck its my friends car i dont wanna break anything in it...since he had to buy that crazy expensive wiring kit and he got the car yesterday...thanks

the outer panel around the keyhole/radio just pops off with a panel tool or a striaghtslot screwdriver. three bolts hold in the radio.
If the theft/security feature is enabled(meaning the little red light flashes) I would disable it or the radio will be junk.

Just as a heads up man, watch out for the little piece in front of the keyring area. If you just pop out the trim it will bust the clips holding this in. You need to turn this piece to allow it to pop out!!
