Building off of Nick's recommendation --
You'll need a cable that, on one end, has two male RCA connections, and on the opposite end, one male stereo 3.5mm connection (if your laptop has an AUX out, this is the best, but it can also be plugged into your laptop's headphones-out port). As he mentioned, it is about $8.
If you have a stock stereo, you will not have AUX inputs, however. You'll need to look at what P.I.E. (Google) offers for your headunit. I purchased one for my 04 6CD changer so that I could run a GPS through the system using the 'SAT' button.
Ask away if you have more questions.
R,
It will be, but will require the coinciding item to have bluetooth, also. I purchased my Dell laptop with BT, but I have not seen it take off like I imagined. I was hoping to have most peripherals bluetooth equipped now - in an effort to lose these damn cords. Hopefully in 08 technology will have caught up with bluetooth.
