[attachmentid=5104]Well after a weeks work I think I have the noise trouble WHIPPED. Digging into my electronic junk box I found most of the parts for this noise filter except the filter it self. Its in a small project box so I can move it from car to car. So far I have tried it on 2 Prius , one package 4, and a package 7. In the seven I used a delfi myfy plugged into the aux jack and the 12 volt plug in the dash. Without the filter a buzz on news and talk channels. Music not as bad ???. With the filter no buzz and no loss of highs as with a ground loop device. In my package everything was the same except the xm device was a sky fi II which is mounted in the car. Results were the same with the buzz gone on news and talk and no loss on the music channels. I will keep the filter in the box until I am sure nobody else in the area wants to try it then I will mount it out of sight in my vehicle.
