1. Follow the path: Control Units -> Information and Communication -> Audio, video, navigation and telematics -> COMAND -> control unit adaptation -> Read coding and change if necessary -> Automatically adjust vehicle-specific and special equipment-specific codings.
  NOTE: This screen will display a list of coding options that are set automatically and a list of options that must be coded directly into the CGW.
2. Press F2 to restart the optical ring
3. Read and verify the coding settings which are now adopted from the CGW.
4. Exit out of SDS and disconnect from the diagnosis port
