HI all.

Having a problem with my iphone when plugged in to charger.
I have it connected through an aux lead to the stereo which works great for the music stored on it and also with the sat nav program and as a hands free kit of sorts, only problem is when I plug it in to the charger via the cigarette lighter I am getting static feedback from the engine which increases with the engine revs.
Can anyone tell me how to rectify this please.

Thanks in advance.
