Often you need a plethora of devices to hook up the car MP3 situation. The Yifang EM192F packs a car charger, FM modulator, and USB MP3/WMA reader via USB into one device. Just jam it in the cigarette lighter, stick in a USB memory stick and wammo, you should be portin’ tunes to your in dash FM stereo. Course I could be totally misinterpreting the poorly detailed product page. Don’t know how much or if it will ever be available here in the US.
