I currently have the stock player in my car, but i have seen cars with aftermarket CD players. So putting in an aftermarket one is pretty easy, and usually cheaper than replacing the OEM one (the 6-disk changer costs $800 CDN at a dealership). It should have 2 little holes or "ports" on either side of it covered by little tabs. Those ports allow it to be removed and with the proper tool (its like $20) you can pretty much do it urself as long as the wiring harness matches the new one ur putting in.
