First timer.
I have some friends that know how to install an aux input for an ipod through a head unit if it supports it. They use a method involving opening up the dash to connect a two-way cable with jacks into the head unit. I was wondering if the rockford fosgate head unit has that capability, how it will affect my warranty, and if there are alternative options for digital input (not radio transmitter). This car is leased, so also is there a way to keep it hidden or reverse the process?
