Its 1-8 if I remember correctly, then it restarts at 1. When you turn on the car and hit cd, it defaults to the aux connection, just press the select up once and youre on the cd changer. Couldnt be any easier to use. Well worth the 40 bucks or so. Dont forget to purchase a 3.5mm cable to go with it. I spent about 10 bucks on a really nice thick shielded cable that was compatable with phone cases. They just taper the sheath to fit down inside the case so you dont have to remove your player or phone from its case. Go with the 5 or 6 foot cable, worked perfectly to run the cable up to the center console.
Is yours a 6 cd changer in the dash or just single?
