Caution!
The update process lasts about 50 minutes. It is necessary for the technician to remain with the vehicle and observe the update process until
completion. During this time, Do NOT: start the vehicle, operate any other vehicle systems, eject the CD or turn power OFF the unit. Any
significant voltage drop in the vehicle could abort the update process. A partially completed update may render the COMAND unit
inoperative. If the update procedure is interrupted, aborts or takes longer than 1 hour, remove the COMAND fuse 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 because
you may not be able to eject the navigation CD since the COMAND unit will remain in the "download-mode".
