[TROK]

Shortly after moving, my father took my '94 GT to the drag strip. I'm sure he didn't touch the stereo, and he says the battery was never disconnected, but now when I turn the power on, the display reads: "BAD" and nothing functions. Can anyone offer advice on fixing this, or what it means?

It's a tape player without a CD player unit. (Although I'd like to replace it with a factory CD/Tape combo from 1994).

Thanks
