I am thinking of either A) getting an aftermarket double-din headunit, or B) I would REALLY like to get some sort of in dash CD changer. Is there such thing as an aftermarket in dash CD changer? The sales people at two different stores here in CO (Car Toys and SoundTrack) told me there is no such thing anymore.

 

You can buy an OEM in-dash CD changer for Nissan at http://carstereohelp.com/sales.htm

I've never done business with them. I just noticed that they have what you are looking for.

 

Blaupunkt makes one. It's the IDC-A09, a five disc in-dash changer. I've been looking into an in-dash approach also because I don't want two openings. What have people been doing?
Here is the link to the Blaupunkt site with the changer: Blaupunkt Cd Changers
Hope that helps
