UPDATE!!!
This morning, while I was driving, I turned on the radio and it came right on!!! It was on an AM station. I drove for a little while, then I decided to see if the FM also had reception. So I pressed the buttom to switch to FM. AND ... just static. I switched back to AM ... AND ... just static. But before I pressed the button, the AM was just fine.
So now I'm thinking the radio actually is indeed working and it's some kind of a connection problem. I pressed the AM/FM button a bunch of times and jiggled the antenna -- just static.
But when I first started the car, the radio worked.
Hmmmmm ....
