I have a MP3 player that I use in my 1998 LS400. It is the Creative Zen Extra. It holds about 10,000 songs (40 gig) and cost about $279. I use it mostly when I travel. I use the Belkin Comcast II (modulator) $39-$49 to interface with my radio. It sends a wireless signal to your FM radio. The key is to get a modulator that allows you to change to different radio stations. They broadcast to a vacant station without causing any interference. But as you travel you may need to find a different station that is vacant. I put it in the center console of my LS, and no wires are visible, so you can't even tell it is there. I have 3,400 plus songs on mine and without having to touch it while travelling never hear the same song twice . I was skeptical about MP3 players, but my brother talked me into getting one, and it is one of the best entertainment investments I have made. I not only use it in the car, but connect it to my home stereo, earphones, a speaker case, and a small stereo my wife has on the counter, all with excellent results. Hope this helps you decide, but I say go for it, you will love the versatility and sound.
