unlocking GM radio LOC code (Page 1/1) fierofrenzy APR 28, 04:46 PM Anybody know how to clear the GM radio display to re-enter in the 2 three digit codes to get the radio to play again. I did it twice, but this time theres InOP on the digital display and I don't know how to clear that out to enter in my codes. Isn't it dumb that they put a lock out on the unit, when all one needs to do is go on You Tube to get around it and get the unit to work. Go figure.....
