Called GM about the problem of the static in the radio when you have something plugged into the cigarette lighter. This only happens when the car is turned on. I happens when I charge my cell phone. It really is bugging me because I bought my Ipod to play in the car. I am using a Griffin transmitter so I can listen through the radio and not use headphones. The transmitter works in my other cars beautifully. GM said is was just maybe a quirk with that model and had no solution. Does anyone else have one??
