Scott,

I just purchased this used E320 and the dealer believes the radios have been swapped and when he ran the radio ID number in the system, it gave a different CODE number than what was included on the Radio Code Card in the owners manual. Needless to say, neither security code seems to work. As a result, I am not sure what the correct Radio ID number is. How do I remove the radio to get this information so that I have it when I contact Becker-NJ ?
