Here is the deal my Acura Tl-ers...I currently have the Zune with Soundgate HONZN4 set-up which is great on my 06 TL (non-Navi). I have steering will control and maintain XM. The output level is low as compared with the factory radio. I max out at 40 whenever I play my Zune. Does the IPod have a low level out when being played?

I want the best cd quality with excellent output that I can get with the factory radio whether its from a Zune or IPod. Also if I go with Ipod what is the best intregation for non-navi that will allow me to keep all my current controls and not lose XM?
