Monday I went out and bought this Monster FM Transmitter to use on my Creative Zen Touch MP3 Player. I got a cigarette lighter splitter for my car, and plugged everything in and it worked like a charm. It only took about 2 minutes to find the best station to use, and as long as I don't keep the power cable on the transmitter coiled up, the sound is crystal clear with no static. I'm assuming that the power cable doubles as an antenna, so coiling it up actually causes transmission issues. If you don't have an auxiliary port on your car stereo, and want to listen to stuff on your MP3 player, this is a great way to go. They also make one specifically for the iPod that will also power the iPod from the cigarette lighter.
