I've seen one but cant rember the name ..... it looked like just a plug to your lighter power and it had some amount of memory that you could download songs on to it so what it is a stand alone mp3 player with a fm transmitter look some what like this but was white and had a few buttons
fm transmitters are very poor quality in my experiences with them. Static and low quality. Better to wire it in from the headphone jack to the aux of your deck.
careful guys! this guy is a JERKY seller! I can see it in his sig! Just step away slowly.. no sudden movements! it will all be ok.
FM signals suck...you can hardly even turn the volume up it is so crappy...headphone jack will sound helluva lot better
