Weird Stereo Issues

I have a 97 GCL. It has the dealer stereo system in it. Recently it started acting weird. I am only able to get in my 2 local radio stations. I do hear static when trying to tune in other stations. Funny thing is that when I'm not in Indiana I'm able to get all the stations. When I'm in Tennessee I have no problems with it. Has anyone else ever had problems like this? What do you think it could be?

i know this thread is ancient but if anyone else has this problem it is most likely a bad antenna or antenna wire.. check that b4 any drastic decisions..
