There are many ways to do so. Each of which is progressively more expensive.
All of these plug into the Ip bus plug in the rear of the unit.
Most of these can be found on Ebay or Amazon
1: An IP bus to RCA plug then you need a RCA to 3.5mm plug wire. (note this is a lower quality) $10-$30

2: An ip bus to Ipod connect plug. (Better sound quality, charges Ipod, does not allow Ipod control from the Head unit, only from the Ipod) around $15-$30

3: An ip bus to Ipod Connectivity unit (same quality as #2 but allows for Ipod control from Head unit)
$100+

Most of these can be found on Ebay or Amazon
