I have the headphone jack aux input cable on my 220 and have it attached to the iPod charger from Monster

This allows me to charge and control my iPod (at least scroll through the songs and stop/play). I set my iPod to shuffle through all my songs and run through them, skipping the ones I don't feel like listening to.
