I've had Satellite Radio for 2 and a half years now, and finally got sick of the cracking from the Wireless FM modulator. So, I wired it in using this: http://www.cardomain.com/item/AVXFMM100A The power is to the radio fuse, and the ground is to a screw in the door. Not sure if that info matters, but I put it just incase. My question is- When I use it, I hear a buzzing in the background that gets louder when I accelerate. Is there a way to get rid of this?
