Hey guys Im new around here and I was looking for some help for hopefully a easy problem. Now I know this doesnt narrow it down much, but Im hearing all of these issues third hand. I advised a buddy of mine who owns a Rumble Bee to go to another buddy of mine to do a stereo installation. The guy is normally extremely good but has ran into a few problems that no one around here seems to know the answer to off hand. He began to install a different head unit and ran into the factory amp and did not have certification to bypass because of the airbag, (or so he says). He swears he has not touched anything, but upon re-installation of the factory headunit it will not switch into CD mode and they said it displays some code and it means "disclock". I dont know if theres any truth to the code, but has anyone else ran into this problem? If anyone has any sort of help I would really appreciate it and thanks for your time and responses. Thanks guys.
