Mercedes Comand S CL class message: Metadata loss

Mercedes Comand NTG3.5 notifications

Do you suddenly get the message “Metadata loss” and/or the navigation no longer works. This problem occurs regularly and is often due to problems with the hard disk on which the navigation data is stored.

This applies to Comand NTG3.5 systems for the S and CL class from 2009. You can recognize these by the fact that they have internal bluetooth telephony.

The repair involves

  • Replace hard drive
  • Firmware update
  • Load navigation data latest version. That is for this type 2014/2015 V11
