Engadget has the story of the Logitec LAT-CARMP3 in-car MP3 player.
At roughly 65 Euros, this looks like an interesting device. It’s basically an FM transmitter that allows you to feed it with a USB pen drive. I often listen to stuff from IT Conversations by burning it to a CD and putting it into my car MP3 CD player, so this would be a good alternative.
I wonder how far its USB support goes. It might be the perfect companion to all those USB drive MP3 players. Maybe it can even play stuff of the USB drive in a Nokia N-Gage??
