Reverse Polarity- Stereo not working

Hey all
I have a 71 Avion camper parked at an RV more or less year round. I have a car radio hooked up and shortly after I moved into the park, the stereo stopped working. My control panel read "Reverse Polarity". I know a little about the topic, but nothing else has been affected. No shocks, or appliances frying. Any clues?

    Does the control panel indicate the 12v system is reversed, or the 120v system?

    Measure the radio's input voltage with a voltmeter and see if the polarity is reversed.

    Sorry, not sure if I'm being clear. There is no car in the situation. I mean to say a stereo you would find in a car. An in dash radio that's in the RV.

    I'm not getting what a car radio and the stereo have to do with each other.
