After replacing my clutch(Thanks Pounder!), when I hooked the battery up after it being unplugged for abou 12hrs the stereo asked me for a 4 digit code. I tried 0123, 1234, 1111, 2222. After the last code entered, the stereo said "Off" and wont let me do anything...I am guessing the computer thinks it was stolen and is asking for a validation code...Anyone have any answers?
