I have a '99 A4 Quattro and I have no manual with it! I need to know the combo of buttons to push in order to take my radio off Safe mode since my battery died! The combo seems to be different every year, so if anyone knows the combo for a '99, please reply ASAP.... Thanks!

 

Hold down the FM2 button and the RDS button until 4 zeros display on the screen, then input the safe code.
