magellan gps accessories

Why is my Magellan Roadmate 2000 interfering with my radio when plugged into the cigarette lighter?

I have a Magellan Roadmate 2000 vehicle GPS (got it for Christmas). It is suction cupped onto the windshield, and has a car adaptor for power. When the adaptor is plugged both into the cigarette lighter and the unit, my FM and AM radio stations get much more staticky, with wierd buzzings and such. As soon as I unplug the adaptor from either the unit or the cigarette lighter, it stops. Obviously the power or something is causing the interference, but is this normal? Is something broken or malfunctioning? Magellan customer support is virtually non existant so I''ve gone to the next best thing...the people! Thanks for your help. It may be operating on the same megahertz as the first responder said, but also I'd be curious why I notice it on some other stations too that are in different spots on the dial?

1. hertz is the answer, It is probably operating on the same megahertz as the radio station you are tuned to. Check the ground inside your power outlet, for cigarette ashes possibly making a poor connection also.. Many electrical accessories interfere with factory computers and radios, such as cell phones can cause static in speakers on newer vehicles. Good luck.
2. It shouldnt be doing this. Try a hard reset on the unit and if it continues, I would return it. My discussions regarding Magellan products has been poor thus far. Good luck!
