I have a 97 Prelude SH i just bought.. like always was playing around with the radio checking out the system must have left something on... came out to jump it everything went dandy till i tryed my radio.. Now it wasnt till i fiddled with the radio and saw the COD thing come up everytime i hit a button till i realized I should go read about it.. I get on find out you need a code i look through the glove compartment VWALAH! there it is but now it wont let me enter it!.. it just says E-03 and doesnt change when i enter the code... any idea on what happend? did I lock it it out or something?
