I got the Belkin adaptor so I can hook my iPhone into the AUX port of my head unit in my 2001 VW Jetta, but i can here very audible interference noises coming through my stereo when i do this. Anyone else experiencing this? The speakers are stock (Monsoon?), the head unit isn't (installed by Circuit City). Hmm, maybe i'll try turning off WiFi and seeing if that helps. But i noticed GSM phones do this with any kind of speakers -- making the interference noise. My girlfriend's phone set down next to my computer speakers would always do it (my old phone was Verizon, so this never happend.) Any tips?
