5.1.4 Speed limit warning

Maps may contain information about the speed limits of the road segments. The software is able to warn

you if you exceed the current limit. This information may not be available for your region (ask your local

dealer), or may not be fully correct for all roads in the map. Speed warning can be fine-tuned in Sound

and Warning settings.

You can set the relative speed above which the application initiates the warning.

The following warning types are available:

• Audio warning: you receive a verbal warning when you exceed the speed limit with the given

percentage.

• Visual warning: the current speed limit is shown on the map when you exceed it (for example:

You can also choose to see the speed limit sign on the map all the time.

5.1.5 Traffic information in route planning

The recommended route is not always the same between two points. Offline statistical traffic information

(historical speed information or traffic patterns) can be taken into account in the route calculation based

on the time of day and the day of week whenever suitable data exists. In addition, real-time traffic

information (INE-Z928HD/INE-NAV-38 only) can help you avoid current traffic events like temporary road

closures or a traffic jam caused by an accident. Both functions are subject to data availability

5.1.5.1 Historical traffic

If statistical traffic information is stored with the map data, the software can take them into account when

planning a route. In normal cases, these statistics help you avoid usual traffic jams on the given day of

week in the given hour but in some cases like on public vacations that fall on normal weekdays, they can

be misleading. You can enable this feature in Traffic settings.

5.1.5.2 Real-time traffic information (TMC) (INE-Z928HD/INE-NAV-38 only)

TMC (Traffic Message Channel) can provide you with the real-time status of the traffic. Route calculation

can avoid road blocks or unexpected traffic jams caused by an accident.

TMC is a specific application of the FM Radio Data System (RDS) used for broadcasting real-time traffic

and weather information.

Using traffic information is enabled by default in the software.

Note!

TMC

is not a global service. It may not be available in your country or region. Ask your

local dealer for coverage details.

Your device contains the TMC receiver that is needed to receive Traffic events.

If public Traffic data is broadcast at your location, the software automatically takes into account the traffic

events received. You do not need to set anything in the program. The receiver will automatically search
