Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
Hello! My name is Gary.Welcome to JustAnswer.I'm reviewing your question now, and will post back with a reply shortly.
Your best bet is to go to your local Holden dealer.
They can look up the radio code from your VIN.
Don't attempt to put in the wrong code, it will go to safe mode, and is harder to get going again.
Your fee should be a one off, unless you become a member, then you have more benefits like more than one question.
Do you need any further help?
I hope my advice has been of assistance to you.
