Put in aftermarket radio and now my radio stations don't work?

So I installed an aftermarket sony radio in my ford escort and now my radio stations are completely fuzzy. Any suggestions? It was perfectly fine before.

Did you remember to hook up the antenna and connect the ground wire to the frame of the car and the back of the radio frame?

Had the same problem. Find the banana plug for the antenna, might have to dig around inside the dash but it should be covered with foam or sone kind of heat insulation. Plug her in and youre good to go.
