SUBJECT:
Model 203, Model Year 2001 and 2002 COMAND Does Not Respond to Voice Controls
If you encounter instances on Model 203 vehicles of COMAND not responding to voice inputs from the Voice Control System, update the COMAND software to SW version 6.23. Dealers have already received copies of the 6.23 update software.
Software installation instructions follow:
1. Turn ignition off and remove key.
2. Turn on the COMAND unit by pressing PWR button.
3. Eject navigation CD-ROM (if installed).
4. Turn off the COMAND unit by pressing the PWR key.
5. Wait a minimum of 15 seconds.
6. Press and hold both the "*" and "# " keys. While continuing to hold the keys down, turn on COMAND by pressing the PWR button.
7. "Service Download from CD" menu appears. Insert update CD-ROM.
Note:
Dates of current and new software will appear. The "new" software date should be more current than the one being replaced. If not, abort the process by selecting CANCEL. If CD-ROM ejects itself and the CD's date of software is newer, reinsert CD-ROM and continue procedure.
8. Using the cursor knob, select START HEAD UNIT (should be selected by default) and then depress the knob to begin the download process.
Caution!
The update process takes up to 50-60 minutes and it is not necessary for the technician to remain with the vehicle and observe the update process. The technician should return to the vehicle after the prescribed time to finish the procedure. During this time, DO NOT start the vehicle, operate any other vehicle systems, eject the CD or power down the COMAND unit. Any significant voltage drop in the vehicle could abort the update process. A partially completed update may render the COMAND unit inoperable. If the update procedure is interrupted, aborts or takes longer than 1 hour, remove the COMAND fuse F4 (located under rear seat) for 30 seconds and restart procedure. DO NOT insert a navigation CD into the COMAND unit if a download via CD-ROM has not been completed successfully. You may not be able to eject the navigation CD because the COMAND unit will remain in the download-mode.
9. When the update process is complete, the screen will display "SW-Download Successful".
10. Eject the Update CD-ROM and insert the navigation CD-ROM.
11. Depress the rotary knob to accept the message and complete the update process. COMAND will return to radio mode.
12. Verify that all modes of COMAND are functioning normally.
