Navigation system* (introduction)
Safety notes
 | Risk of accident |
|
For safety reasons, only enter a new destination when the vehicle is stationary.
COMAND calculates the route to the destination without taking account of the following, for example:
For this reason, you must always observe applicable road and traffic controls and regulations during your journey. Road and traffic controls and regulations always have priority over the navigation announcements generated by the system.
|
Updating the 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The digital maps generated by the map software become outdated in the same way as conventional road maps.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 a Mercedes-Benz Service Centre.
You can update the map software yourself using a DVD.
To update the map software, carry out the following steps:
 | |
|
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 system and to cancel the process. Other functions are not operational. If possible, carry out the update when the vehicle is stationary. The DVD read speed is higher when the vehicle is stationary than when it is in motion, so the update will be quicker. 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.
|
| Risk of poisoning |
|
Never leave the engine running in enclosed spaces. The exhaust gases contain carbon monoxide. Inhaling exhaust fumes constitutes a health hazard and could lead to loss of consciousness or even death.

Notes about handling DVDs
-
Only hold discs by the edge.
-
Handle discs carefully to prevent reading errors.
-
Avoid getting scratches, fingerprints and dust on discs.
-
Use a commercially available cleaning cloth to clean discs. Do not wipe them with a circular motion, but only in straight lines from the centre outwards.
-
Place discs back in their cases after use.
-
Protect discs from heat and direct sunlight.

|
| |
|
The navigation system remains fully operational with the previous map data.
|
The following circumstances can cause the update to fail:
General notes
Operational readiness of the navigation system
After delivery of the vehicle
In vehicles for certain countries, the navigation system is not operational immediately after delivery because the map software is not pre-installed there.
If this is the case, you will be made aware of this fact by the following message appearing when you switch to navigation mode: The map software must be installed. Please insert the DVD containing the map software.
| |
To install the map software: proceed as described in the "Updating the map software" section more.
|
| |
|
In this case, please allow the update to run to the end. If you cancel it, the navigation system will not be operational.
|
After a system software update
After a system software update at a Mercedes-Benz Service Centre, the installed map software may no longer be compatible. If this is the case, the navigation system will not be operational.
In this case, the following message will appear when you switch to navigation mode: The system software has been updated. The map software must be updated now. Please insert the DVD containing the map software.
| |
To update the map software: proceed as described in the "Updating the map software" section more. Use map software which is compatible with the system software.
|
| |
|
Please note that in this case, the update must be allowed to run to the end. If you cancel it, the navigation system will continue to be non-operational.
|
The navigation system must determine the position of the vehicle before first use or whenever operational status is restored. You may have to drive for a while before precise route guidance is possible.
GPS reception
Correct functioning of the navigation system depends amongst other things on GPS reception. In certain situations, GPS reception may be impaired, there may be interference or there may be no reception at all, e.g. in tunnels, in multi-storey car parks or due to snow on the GPS aerial. If there is snow on the GPS aerial, you should remove it. The GPS aerial is on the roof at the rear.
Route guidance after vehicle transportation or exiting a multi-storey car park
COMAND will need to recalculate the vehicle's position if the vehicle has been transported, e.g.:
-
by ferry
-
by motorail
-
after being towed
In some cases, COMAND will also need to recalculate the vehicle's position after exiting a multi-storey car park.
Positioning takes place automatically even when COMAND is switched off. The duration will vary from one situation to another.
Route guidance may be restricted as follows during vehicle positioning:
-
Navigation announcements, route guidance displays and displayed street names are not consistent with the actual location of the vehicle.
-
COMAND does not generate navigation announcements.
-
Instead of the route guidance displays, you see the Off road display and a directional arrow. The directional arrow shows the compass heading to the destination.
When positioning is complete, route guidance is resumed with navigation announcements and route guidance displays.
Interrupting the journey duration route guidance
| |
|
Interrupting the journey means parking the vehicle and switching off COMAND. Continuing the journey means switching COMAND on again and driving on.
|
The following applies if you interrupt the journey during route guidance and continue the journey later on:
-
COMAND resumes route guidance automatically if you continue the journey within 2 hours.
-
Route guidance is cancelled if you continue the journey after more than 2 hours. It will be necessary to resume the cancelled route guidance manually .
Hard disk errors
COMAND has an integrated hard disk on which the map software is stored.
If an area of the hard disk has a fault, COMAND can no longer access the map data in this area, for example when calculating a route.
In this case, the message Navigation unavailable. Please observe the operating instructions. will appear.
| |
To delete the message: switch COMAND off and then on again.
|
If you switch the navigation system off / on, it will be operational again until it has to access the faulty area of the hard disk again. The message will then appear again. Consult a Mercedes-Benz Service Centre.
Units of measurement
The units of measurement in navigation mode are identical to those set in the instrument cluster.
Input restrictions
On vehicles for certain countries, there is a restriction on entering data.
The restriction is active above a vehicle speed of about 5 km/h. The restriction is deactivated as soon as the vehicle speed drops below about 3 km/h.
When the restriction is active it is not possible to enter specific items, e.g. town or road name. You will be aware of this because certain menu items cannot be selected.

Selecting the
route type
You can select the following
route types:
-
Fastest
route: COMAND calculates a route with the shortest possible
(minimised) journey time.
-
Dynamic
route: same route type as
Fastest route. However, COMAND also takes into
consideration any RDS-TMC traffic announcements
that are received for route guidance.
The navigation system is thus able to guide you around a traffic jam, for
example. If a quicker route is determined due to a received RDS-TMC
traffic announcement, the navigation system changes the route. It will bypass
blockages if possible.
-
Short
route: COMAND calculates a route with the shortest possible
(minimised) distance regarding distance and driving time.
| |
|
COMAND calculates a
new route if you change the route type setting with route guidance active. If
you change the route type setting when route guidance is inactive, COMAND uses
the new setting for the next route guidance.
