You will need an RCA jack; they are very cheap and can be bought almost anywhere. Basically, they are cords that look like headphone cords, with two headphone plugs at the end, instead of just one headphone plug, like on a regular set of headphones. My dad has a 2008 Hyundai Elantra that also has an auxiliary input jack that was preinstalled; I was told that I would need an RCA jack in order to play my Ipod via the auxiliary input jack.
