Navigation "high-end": Functional description

I - BASIC PRINCIPLES OF THE TRAFFIC INFORMATION SERVICE

Coupled with navigation, the system provides traffic status information: "TMC: Traffic Message Channel".

The system uses:

• the navigation control unit, which receives, locates and processes the information received,
• the TMC location codes stored on the map CD-ROM,
• the information collected and broadcast (by the public authorities) in RDS-TMC format (communication protocol).

Traffic information collection and broadcast services in Europe, for which RENAULT is not responsible, are still evolving

II - REMINDERS ON HOW THE TERMINAL PROCESSES TRAFFIC INFORMATION

TMC icon display logic:

• Red = no traffic information broadcast in this geographic area, or insufficient reception,
• Black = no traffic information location codes on CD,
• Green = the system is tuned to a frequency that can broadcast traffic information.

The term "TMC" is replaced by the name of the service provider the system is tuned to (if the provider broadcasts a name).

The system can display information as text or as icons.

It suggests a detour if the disruption is on the calculated route.

The disruption level is shown by a "Δ H" icon:

• Green = disruption with diversion,
• Red = disruption without diversion,
• Solid red = very major disruption within a 50 km radius.
