i have a siemens ncdc 2013 GID in my signum, only bought last last year.
The radio works but unless its in MAIN mode i get "radio safe" and a beep every 10 secs. I have the code but it will not let me enter it anywhere.
I know your supposed to press AS and power and wait for a beep but all it does is turn the radio on when i try.
Is it goosed or does it need a recode or something?
