1999 BMW M3 mileage: 91,000. This is embarrassing. When I went to jump start my wife's car, I accidentally hooked up the battery cable wrong. This resulted in cross polarity, which melted the negative battery terminal right off the "bad" battery. I've had a new battery and battery terminal installed and the car seems to be running fine. However, the radio no longer works. I've checked the radio fuse in the fuse box, and it is fine. Is there anything else I can check or did I fry my radio during the cross polarity?

Don't be embarrassed. You aren't the only one who has made this mistake. It is possible that you did "fry" it. However, it is more likely that your radio has an anti-theft devise built into it. When a battery is disconnected, the dealer must reset the radio.
