I'm playing my iPod / iPhone through the headphone output and it sounds just fine. But I have a cigarette lighter charger for it, and as soon as I plug it in I hear a high pitched whine. Any way to get rid of it? I tried a few different chargers and they both had same result.
Stereo is a MB Quart with the driver side remote. I have a cable for direct input, but it's a bit clumsy and it doesn't work with the iPhone.
