RF engineer to the rescue! I have the same wine from my sirius sat. reciever, however, I ran my 3.5mm cable out to the cd changer cause I dont have the radio removal tools.. yet.. I will look into this & post up a solution...
1st guess is a ground loop has been created somwhere.. In the RF world, ground loops are super bad because they are in effect really good antennas & introduce all kinds of noise into a circuit...
if you want a quick fix, well a ferite loop filter should do the trick, but for me I have to know exactly what the cause is.. its an engineer/OCD thing..
