same here!CD player is ok here too, though I don't really use it.
I listen music from my phone that is connected to a bluetooth-module and that is connected to AUX input.
I just purchased this and it is working just like I want to and there is no need to change batteries ever + there is a remote controller with a speaker in it:same here!
USB is good but not same as selection you can get online with phone.
I have to recommend something like this to go into 3.5mm aux. Solid
