Excelvan FM Transmitter + Car Charger + Remote Control Compatible with iPhone 4S/4/3GS/3G iPOD
Transmitter does not work at all.  Tried every frequency on both radio and transmitter.  Nothing.<br />If it worked badly, I could understand as the price was cheap.  Not working at all is terrible.  Costs more to return it, so I just have to eat this one.  Avoid!
