i bought a fm transmitter to play the ipod on the 88 E30 car's stock radio (premium), i picked a frequency on the radio and transmitter, although i can hear the music there is this swooshing noise on the background very irritating.
can anyone give input as to why, is my radio obsolete, does my antenna have to be raised as well.
do i have to try certain frequencies.
or last option being to replace the stock unit.
thanks
