Did the radio/CD player get hosed?

I bought a battery at an autozone. They replaced it with the wrong type - opposite terminals. I didn't notice until after the car wouldn't crank. They then put in the correct one but the car never started. Next day they had an electrician fix it and everything works fine except for the Pioneer CD radio. I am handy with cars and learned I should have done it myself. I haven't worked on car radio but from back in the day I know they used to have inline fuses. It's a bit of some work to remove it and I wanted to know what likely happens to it when battery terminals polarities are swapped before I have to remove it? If it's just the inline fuse I can replace that myself. The car is a 1997 Toyota Camry LE

The radios are protected inside by reverse polarity protection diodes and inline fuses.
If you're lucky... just the fuse blew in the power line.
