Paul, I would bring them. If I had the extra $, I would get one as a backup. I love riding with my ipod. On an IS, double male connector (extension available at almost all Walmarts - I picked my present one up at the base of Cheaha when the cord would only play out one side) and plug into connector behind right side cover and TUNES BABY!
That is my iPod hanging off my right hand handlebar. Cheap black case (that is about to wear out after 3 years or so) hangs it from the throttle lock.

Also picked up a car charger for the iPod at Walmart a few years ago when on the road - don't remember where - maybe Texas. Charge as I ride in case the power goes out before I can charge it up in a hotel room at night.
That is the charger wrapped around my handlebar. Anyway, I LOVE MINE!!!!!! Makes the perfect riding tunes machine.
