Hi, Im having trouble with my astra's radio needing a code. Upon reading through these threads I have found most of the answers i am looking for in regards to how to fix it. I know it was the NRMA guy that replaced my dead battery without plugging the power supply into the ciggarette lighter that has broken it. I know i need the numbers on the side of the unit, i know how to input the code to fix it, but the code itself is missing from the mix. can anyone out there help me out with a code please? details = 2003 Holden Astra blaupunkt 520 cd player 92 057 951 BP 239130786845
