My keypad on my radio is not working. Is there anything I can do to fix it? I do have my code for the radio. It used to work fine and now the keypad does nothing. Everything else works. Just the keypad is messed up. When it worked i push the keypad and the stations would change. Then one day my wife was driving it and she said some weird letters was on the display and then static. We tried to change the station but nothing but static. Then I disconnected the battery and now it will not let me put the code in. So what can i do to fix it or can i fix it?
