Simply by DIN to RCA to iPod. Important: It is best NOT the iPod via mini-jack / headphone out, but via a dock cable to RCA to the adapter!
The quality of the adapter is not high-end but serviceable.
For high-end pleasure with IPOD there with a corresponding system at home (high-quality digital-to-analog converter, for example, in the AV amplifier) a recommendation Wadja I transport!
Enjoy Yourself!
