How do you put your code into your radio for CDC safe on your Vauxhall Astra if it is in CDC safe mode?

To unlock your Vauxhall Astra's radio from CDC Safe mode, first ensure the vehicle is on and the radio is powered. Then, enter the correct security code using the radio's preset buttons. Typically, you would press and hold the "1" button for the first digit, "2" for the second, and so on until all digits are entered. After entering the code, the radio should unlock and return to normal operation.
