I am a newbie who just got my 30 gig Rio. I currently have an Eclipse 55430 head unit in my car, which I want to run the Rio into. There is no aux inputs on the headunit, but it does have cd changer controls. Has anyone ever tapped into these controls to hook up the unit? Any info would be great. BTW, if you were wondering why I don't use the rio as my main headunit, it is because the eclipse has 3 sets of 5V preouts which I use for my speakers and subs. Thanks.
