I was wondering what is the best option for hardwiring a 20 gig I pod to a aftermarket pioneer headunit

thanks for your help

 

Does your head unit have aux input? Just a basic RCA to microjack adapter would work fine. Or if not, and if your unit has cd changer controls, see if Pioneer makes a changer-to-RCA plug, which you could then use for whatever you want. Other than this, a hardwired fm modulator is the best option.
