Mercedes-Benz changing region COMAND NTG 3.5 4.5 4.7 5.1

As of Model Year 2010 (207/212 models), the COMAND system can be switched between European (ECE) and USA variants (“modes”). This feature is useful for:

• USA vehicles purchased in Europe and intended for temporary use there (e.g., European Delivery Program, military, diplomats).
• Temporarily converting a USA-market vehicle to ECE mode for European navigation and features.
• Switching back to USA mode upon return to the USA without needing Star Diagnosis.
  Note: Requires a valid, official, and legally acquired USA Map Database DVD for the specific model.
  Warning: ECE (European Variant) mode enables basic Telematics functions in Europe when the Customer Center/Workshop in Germany changes the COMAND variant to European mode.
