probably an antenna problem. Check to see if the antenna is firmly tightened in place. Then I'd suggest checking or maybe even replacing the antenna cable. I'm pretty sure the cable is sadly a dealer-only part. If you confirm the antenna and cable are good, I'd suggest trying a different radio.
Walmart carries some cheap AM/FM Radios with a CD player (I've heard good things about a $90 sony deck)
