Has anyone installed an aftermarket radio yet? You can buy the base radio plate from Nissan parts and Metra has a kit for the base model. I just don't have the funds to spend over a hundred dollars to ty it yet. I'm no so sure it will work with my 6 disk changer, and I would have to cut holes for 2 or 3 of my options that the base does not have. I have only seen custom fiberglass dash jobs that have an aftermarket stereo in them so far online. Anybody?
