2004 Jetta Radio

first i lost am (yaes am!) reception, now the fm reception seems to be fading: lots of disturbance and static. anyone else experience the same? is there an easy, cost-effective fix? Same problem started last year...now I can't get anything in....I got a sirus radio for XMAS and that was the only fix I could find...but that fades out every now and again too...I will look under the antenna boot later today. Thanks for the advice...also how the heck do you search in tdiclub I became a member but don't see and area to search to forums.
