For those of you that have an iPod, I purchased a Belkin Auto adapter to charge my iPod while playing and it works great:

Belkin : Auto Kit for iPod w/ Dock Connector

I purchased an additional stereo cable that plug into the charger section and into the iPod and GREAT SOUND!

I also velcro'd the iPod in a case next to the shifter so it's handy.
