Terrible radio static am/fm

[Recmar1]

Has anyone come across this problem? The radio has horrible static on both AM and FM. It's so bad across most channels, sometime I actually miss what is being said or played. It seems to at times, increase when I add pressure to the gas pedal! Haven't hooked up my XM yet, so can't speak to that. There seems to be a smaller amount when my Ipod is plugged in. Any help would be appreciated.
