help. no radio stations

[fordby4]

The other day I was driving and then all of a sudden the radio stations stopped working. It is an aftermarket sony cd player and it plays when a cd is in but just doesnt pick up any radio stations. Not even static. I checked all the connections in the back and everything seems okay. I am stumped. Any help will be appreciated. thanks

How old is the headunit, it could just be wearing out. I had a kenwood that after about 3yrs the display starting dying, I had to have it warrentied.
