Not sure if a code will help actually.
Car been standing for two years but decided to break for parts. Have had an enquiry about the radio so need to see if its any good. Have the GM passport number for the radio but its constantly showing 'SAFE' on the display. It doesn't change to 10_ _ _ _ to allow me to enter a code.
Is it knackered or permanently locked or is it possible someone has in the past entered a wrong code a few times and its gone into a wait state before it allows another attempt? (">
