I have an older Eclipse CD5441, with a set of aux inputs in the back of the deck. I bought the cable that goes from my Zune to the RCA hookups, and it will play through the deck, but I have no control of volume or bass and treble or anything of the sort. Is this normal or do I need something else?
I would like to upgrade to a new deck, and I have searched the forums, and everything I am seeing is requiring me to go through aux inputs for my Zune. Is there a deck out there(Alpine, Clarion,Eclipse) that has a 3.5mm jack or aux rca's that will let me plug my Zune in and let me still have control over the audio?

Thanks!
