Here's a thread I posted with pictures earlier. Input jacks and wired headphone jacks on both sides, wireless headphones included, modulator built in to both so either or both will play through the car stereo, disc is loaded into the top of each. As I said in the other thread, each one can play its own disc, the others disc, or both can play the same disc loaded into either unit. Also plays music and MP3 CDs. See pictures here:
