Mach 460 "BAD" error

[AcE XBOX]

I have a 96 GT and I turned it on the other day. The battery had died so I had to jump it. When I tried to turn on the unit it showed on the display "BAD" so im thinking wtf? Well I cant do **** with it. It turns on but I cant move anything. Cant change station or volume, nothing. When I stick a CD it does work but I cant adjust anything. Any help?

Try dissconnecting the head unit from the power source and then plugging it back in. The unit may have to reset itself internally when its powered back up. Otherwise it sounds like you fried some of the circuits.
