I have an E36 with the standard anti-theft radio. It says CODE on the display, and apparently my wife and child attempted several inputs, and now the radio will not reset even when the correct code is input.
I have two different radios with the same trouble. (this is my second E36, and I kept the radio and owner's manual set from the first car, and this is what is now installed in the second car.)
What the problem is ... Even though I input the correct code, the radio(s) is convinced that it is stolen. How do I retrain the radio that it is not stolen so that I can input the correct code and get the radio working again? (I have two radios, and two Code Cards, so I know the correct code for each unit.)
