You can program the Concert radio to use either the standard or the Bose equalization setting, as well as a few other basic configurations. This requires the use of a VAG-1551, VAG-1552 or equivalent scan tool (See VAG-COM or ProDiag). Knowledge of the usage of such a scan tool is assumed.

 Connect scan tool to the car's OBD-II diagnotic port.
 Turn on ignition and radio, select Radio Controller in scan tool.
 The radio shows "DIAG" in the display.
 Select "Recode Module". You may enter a 5-digit code according to the table below. For example, "00007" is a standard setting while "00017" is a Bose setting, both with CD changer and secondary display.
 Turn off radio and ignition, disconnect scan tool.
 Turn on radio to hear the effects. In Bose mode, the radio display will show "BOSE" briefly after turn-on.
