Mercedes-Benz ML320. Manual — part 239

Fig. 53: Identifying Digitized And Non Digitized CD-ROM Map Areas

The road network is indicated in extremely simplified form.

Guidance is the generation and output of driving recommendations, in order to guide the driver to the desired
destination. The prerequisites for route guidance are:



Permanent location finding is in operation (is accomplished automatically),



destination has been entered and



the route has been calculated.

The navigation processor permanently compares the data from route calculation with the data from permanent
location finding using this information for measures for further guidance . Two route guidance operating modes
can be distinguished depending on the vehicle position (see figure):



Guidance within the digitized CD-ROM map area.



Limited guidance outside of the digitized CD-ROM map area.

Fig. 54: Display Layout Of Radio (A2) During Navigation - Shown On Model 203

When traveling within the digitized map area, the following information calculated by the navigation processor
is available to the user (partially to be called with "I" (INFO) button):



Route list indicating the distance to be driven on the affected streets or roads



Distance to destination and estimated time of arrival (the time must be set correctly for this purpose).



Driving recommendations



Arrow indicating the driving direction



Current location, in other words name of city and street, latitude and longitude



Name of the next road into which the vehicle should turn



Distance to next turning point specified in units of length or as bar graph (3)

The navigation processor generates graphic signals for the navigation system symbols.

Actual route guidance is supported by voice output via the vehicle loudspeakers.

When driving within the digitized map area the following information is available to the user:



Current position and vehicle route on digital map (illustrated in figure)



Distance from destination and anticipated time of arrival



Driving direction recommendation



Distance to next turning point (specified in units of length)

The data is determined by the navigation processor and transmitted to the radio and navigation module
(A2/56) The current route guidance is primarily supported by the voice output (English).

The scale of the displayed map can be changed in increments. In addition it is possible to select whether the

map is aligned in the direction of motion Head-Up ) or toward the north North-Up ). The graphical signals for
map illustration is generated by the navigation processor.

When traveling outside of the digitized map area (e.g. company grounds, parking buildings, dirt roads,...),
however still within the DVD map boundaries, the navigation processor switches over to "navigation system in
non-digitized map area".

On the radio (A2) display the following message appears:



"OFF ROAD"

If the vehicle is also outside the DVD map limit, the following message appears:



"OFF MAP"

In both cases, only basic location finding is accomplished with correction using the GPS data.

A (limited) route guidance can be conducted only with specification of the:



Distance from the destination as the crow flies



Direction to the destination (as an arrow)

After reentering the digitized map area, the system automatically continues with "navigation system in digitized
map area". The possible streets/roads on which the vehicle may be located are determined with the aid of GPS
location finding. During this process a slight delay in the route guidance may result.

The road data of several Central European countries are stored on the navigation DVD, so that the "OFF

MAP" message will not appear, if borders between the stored countries are crossed. No special foreign country
DVD has to be inserted.

When traveling outside of the digitized map area (e.g. company grounds, parking buildings, dirt roads,...),
however still within the CD-ROM map boundaries, the navigation processor switches over to " Guidance in
non-digitized map area " .

The following message appears on the display of the radio and navigation module (A2/56) :

"OFF ROAD "

In this case only basic location finding (dead reckoning) with correction by the GPS data is performed (no map
matching )

After reentering the digitized map area, the system automatically continues with " Guidance in digitized map
area ".

With the aid of the GPS position the possible roads, on which the vehicle could be located, are determined.
However, this can result in temporary delays in the guidance function.
