When the vehicle has been out of use for a long period, CARMINAT ’S

performance may be temporarily affected. As soon as GPS reception reaches a

sufficient level CARMINAT will resume normal functioning.

■ Reduction in GPS reception

When GPS reception is interrupted or disrupted over several kilometres, there is also a

possibility of it malfunctioning.

Disturbed or non-existent reception:

• In indoor car parks, tunnels or under bridges.

• Between high buildings.

• In woods or avenues of trees.

• During heavy rainfall or storms.

• In mountain valleys.

The CARMINAT system can compensate over several kilometres for problems in

reception without loss of function.

■ Digital road map

To plan an itinerary to a destination, the CARMINAT system needs not only the current position

of the vehicle but also a digital road map on which the address of the destination is recorded

plus the different approach roads leading to this point. You will find this digital road map on

the Cartographic CD that you insert in the navigation computer.

■ Areas where road information is limited

In some areas not all the information regarding a road or a route is available on the

Cartographic CD. Data such as no U-turns, one-way streets or signs indicating pedestrian

areas may be lacking. The system will tell you when you enter such areas and will display a

warning

(in red)

The highway code always takes precedence over CARMINAT ’s indications. In all cases

obey road signs and the highway code.

■ Basic principals for loading info traffic

The Carminat system organises information about traffic conditions: TMC: Traffic Message Chanel.

The system uses:

• Information gathered (in general from public authorities) then broadcast by operators

(public or private) via the communication protocol RDS TMC.

• The local navigation calculations take into account information received.

The performance of an information service depends on:

• The geographic coverage (number of kms of roads covered) (linked to collection and to

broadcast).

• The response time between the appearance (respectively disappearance) of a traffic

disruption and its broadcast) (respectively the end of the broadcast) (linked to the collection

and the broadcast).
