ok so I bought a Belkin Fm Transmitter at the apple store yesterday and when I plugged in into the 12volt everything was fine...until i started driving.  It was all static and no music with the occasional radio station interference.  It was definitely NOT worth the $80 I payed for it  and I'm returning it today.  Any suggestions on what product is best for playing my ipod? 
  
Thanks,
