Control systems COMAND navigation (introduction) COMAND navigation (introduction) Map software The digital maps generated by the map software become outdated in the same way as conventional road maps. Optimum route guidance can only be provided by the navigation system in conjunction with the most up-to-date map software. Information about new map software versions can be obtained from an authorized Mercedes-Benz Center. Updating the map software You can update the map software yourself using a DVD. Notes about handling DVDs Only hold discs by the edge. Handle discs carefully to prevent read problems. Avoid getting scratches, fingerprints and dust on discs. The updating process has the following phases: Loading a DVD into the DVD changer ( page 160) Updating process ( page 160) Use a commercially-available cleaning cloth to clean discs. Do not wipe them with a circular motion, but only in straight lines from the center outwards. Place discs back in their boxes after use. Protect discs from heat and direct sunlight. Updating process i The updating process can take between 10 and 60 minutes, depending on the size of the map software. If the radio was switched on before you started the updating process, you can still adjust the volume. You can also use COMAND to operate the automatic air conditioning and to cancel the process. Other functions are not operational. If possible, carry out the update when the vehicle is stationary. i If you carry out the update with the engine switched off and the vehicle battery has insufficient power, COMAND may automatically switch off during the process in order to protect the battery. If this occurs, restart the update with the engine running period. Similarly, if the SmartKey position is unintentionally switched to 0, restart the update. Warning! G Never leave the engine running in an enclosed space. The exhaust gases contain carbon monoxide. Inhaling exhaust gases constitutes a health hazard and could lead to loss of consciousness or even death. 159
