In my truck I listen to my ipod via an FM transmitter I plug it into the cigarette lighter (run off the car battery). This works fine unless I have my ipod charger plugged into the cigarette lighter and my ipod. Then the FM signal gets terrible. If I just have the charger plugged into the cigarette lighter and not in the ipod it works fine, only when it is plugged into the ipod does it give me problems. Any ideas on how to fix this? My guess is it is having a problem with a common ground, but I don't really know.
Thanks
