This seems simple but I just don't know. Would there be any complications swapping a 2004 Audiophile head unit into my 2003? I want it to get the auxilary input for my Ipod while still staying stock and having the sub and all.
Then whats the AUX button for? Is there a plug for an external CD changer? There's got to be some kind of input! I have a 2003 which does not have it, I have heard the 2004 does have at the very least, a button on the front that says "AUX".
