Hello! I just purchased an Audi two days ago and the radio is locked in SAFE mode. Can you please help me with finding the correct code to unlock the stereo so I can actually listen to music in my car!? Not sure what you need but here is what I could get from all the stickers/bar codes form the head unit: Serial Number - AUZ5Z6W006 Concert 4B0 035 186 A HC 200 Hope you can do something with this, have read lots about beer money, I just want my stereo to work so I'll GLADLY send you enough money for a fun night! Thanks.
