Hi, I have just replaced the electric aerial on my 430. In doing so, the electrics were disconnected and after powering up, I am locked out of the audio system. The screen just states ‘SEC’.
I have the 3-digit code and have followed the reset procedure several times. The procedure doesn’t make sense and it doesn’t even get me to a point where the system asks for the security code to be entered. Can anyone help with a step by step guide to resetting the system?
