My wife has a 2000 XC70 SE. It has a single-disk CD player in dash.

I'd like to connect an external GPS/MP3 player. I just need shielded L/R audio in to an aux channel.

I'm wondering if there is anywhere I can buy a module that will interface with the audio bus to connect an external aux audio device. I don't need one that speaks 'iPod' to get all the other features. Just left/right analog in would be fine.

Anyone know how hard if anything like that is available? How hard it would be to hook up?

(I did this with my 2005 Ford 500 by buying an interface module and then just plugging it into the audio out of my GPS/MP3 player. It was pretty easy.)
