When I stream audio (via Pandora, MLB At Bat, Public Radio Live Stream, IHeartRadio, etc) and listen through my car stereo via the aux-in port, the audio sounds great. However, if I also have the phone plugged in to the cigarette lighter charger at the same time, the sound has significantly more static. When I unplug the charger, the static immediately goes away and the sound returns to high-quality. I've tried several different cables (both aux and charger) thinking that there was a shielding problem. Has anyone else experienced this, and does anyone have a solution or a combination of cables that provides the same good sound when the phone is charging as when it is not?
