the only inputs are the standard aux rca inputs a CeNet input/output which i assume is for a stacker and an optical which is both a input and output
from all the reviews i've seen there is a adapter for an ipod mentioned so i guess there is one! but i actually congratulate clarion for not putting anything on the unit for mp3' as really, it would completly defete's its purpose it was never intended to help kick along the marketing hype behind the whole mp3/ipod craze..... just to be the best cd transport!
mind you i never bought it for a sq deck! i just wanted a decient deck without the all the crap that i never use sounds as good as its going to get and dosent have a flimsy feel to it... simple
its a pity about the remote though

im tempted to ring there head office and demand they me make one that dosent feel like its for a $120 sound4 deck!!! its absolute crap for some reason they must think nobody uses them any more.
oh and it replaces my trusty never failed tough as all crap 8 year old pioneer DEHP736 deck which had the best remote! even if i am on my second one
