Hi there everyone. I just bought a 2002 S60 yesterday and I have an aftermarket stereo I want to put in. I don't want to tear up any of the interior so I figured I would ask and see if anyone knows how to take out the old stereo and if I need anything other than the wiring harness to get it working. I have don't some installs on newer cars that require a little computer wired in to the stereo that connects with the rest of the cars computers to function correctly. Any help would be much appreciated. Thanks in advance.

 

Here you can see where the screws are located, Dont forget to disconnect your battery before you remove the stereo.
As far as i know Volvo sells adapters for aftermarket stereos but i have never installed one so i will let someone else explain
how to do that.
