Stereo & Electronics - Tuner Going Bad?

I have a 1998 Z28. When i put the radio on the sound gets static. Its not alot but enough to annoy you, but when i put a cd in its perfectly fine. Would This be my tuner going bad? IDK much about this so any help is appreciated. Oh and if it is bad where can i get a OEM one.

Thanks
Chris

It's more likely your antenna is bad (or even unplugged - have you pulled the radio out of the dash recently?)

no im the second owner so maybe the orginal owner did but my dad works for Cadillac and go an antenna off a newer car so i dont think its the antenna.

anyone??
