Ditto, don't bother w/ an OEM deck or security. I ripped out the stock radio (left the tape player in so there wouldn't be a big hole) and replaced it w/ aftermarket. Much better and have a CD player. Also, I have the aftermarket security. That way, I don't even need the OEM deck in the back of the new radio to make it work. In case you didn't know, you have to have the OEM deck behind an aftermarket if you wanna keep the stock keyless.
