Getting MP3s Into The Cockpit

I have been looking for easy ways to get the music from my MP3 player into the cockpit of my 21ft boat that I use to travel the Amsterdam canals. Here’s a good, and weather-resistant, solution called Tivoli PAL or iPAL.
“The tiny PAL has an amazing rich and deep sound. You plug an iPod in, turn up the volume, and it uses its internal rechargeable battery to play your musical playlists longer than your iPod battery will last (I can get 8 hours on the PAL in one charge). Clear, marvelous sound from a small, rugged box that has survived rain and being dropped into a pool. That doesn’t usually happen because it is carefully designed with handy finger grips and a grippy covering. It comes with an adapter for running on AC.”
