    Hello Everybody,

    I'm having a noise problem when the iPod is connected to the Aux input of the car stereo. The noise comes only when connecting a 12Vdc iPod battery charger to the iPod (car cigarette lighter adapter), no matter the car engine is running or not. I've noticed that the hi-freq noise is something generated by the iPod itself, therefore it looks like this noise goes back to the car stereo thorugh the battery charger.
    My question is, could this noise be eliminated by applying a low-pass filter between the iPod battery charger and the car 12V dc source?

    I would greatly appreciate your suggestions and comments:D. Thank you!
