I mentioned I your other thread that you can get a simple Radio Shack cable to plug into those red and white jacks (which are the Aux audio input) or if you have an iPhone, use the special Nissan cable to plug in the iPhone.
Personally, I just bought a used classic iPod and sync all my music to it using a special iTunes setup. If they come out with a >64GB iPod Touch, I'll buy that and have it sync with iCloud when I park on the carport
