I have downloaded audio books on my iPad (original), instead of using ear plugs to listen to my books. Can I use this device and listen to my books

Through the car stero system? I'm looking at the Belkin 3.5mm dolled stero cables to buy will this device work so I can listen to my audiobooks through the car stero?
