Hi All,

I have the "normal" buzzing, garbling background noise when I use the audio input (auxmod) and an ipod docking/charging device. If running on the ipod battery power no issues. I purchased a "power filiter" and installed it on the hot lead to the cigarette lighter, then grounded it to the car by sandwiching the wire between the car tunnel and the shifter metal bracket. This helped a lot with the alternator noise but the garbling/warbling (not sure how else to describe it) noise is still there. I was wondering if putting the ignition lead through the filter as well would help. There is no power on that wire but it might be another conduit for the interference????? Any thoughts on this?

Thanks,

 

You' might be better off putting a ground loop isolator on the line outputs that run from the ipod to the head unit.

Groud loops are mysterious though. Preventing the Ipod from using it's audio outputs as a ground conduit would be the first thing I'd do.

 

I will try that....filter at both ends...power and audio should do the trick.

Thanks,
