hey guys. need some help. I checked all fuses and all are fine.[ but for some reason, now my premier only plays cd's. it'll switch to "tuner" mode for the radio but there's no reception at all. no signal. i dont know why. i have the s2000 antenna but nothing's really changed. i shorted out the headunit but replaced the fuse and it's fine but the radio doesn't work for some reason. any ideaS as to what it could be? thanks.

have you checked the antenna connections in the back of the stereo and on the antenna itself?
