Radio in 09 Challenger????

Hey all. Hope everyone is doing good today:-D.

My question is for those of you that have the new Challenger or know of this issue. My son, who is in the Army recently got deployed to Afgan. So insteed of storing his car, 09 Challenger R\T, I got it, woooohoooo:cheers:. It had sat radio that just expired. And since the car will be parked most of the time we did not renew. But I drove the car the other day, turned on the radio to listen to some tunes and all I got was static:angry7:. Even trying to get the very local stations. What gives? Anyone know of why the radio will not pick up? It's like there is no anntena. Is this a common issue? I have not got with a dealer yet due to no time now. Are any of you haveing the same issue? Please help. We can still use the AUX hookup to hear the IPOD but not the radio. HELPPPPPP
Thanks for any help.
