2016 Discovery 4


Any traffic event (broadcast on TMC) in your area, will be displayed as a warning icon on the map.

In case of lost reception, this data is stored in the system for up to 15 minutes.

The color of the TMC icon changes to indicate the type and priority of a TMC event. The background color of the icon returns to normal when there is no longer an event or hold-up, or if any re-route instructions are calculated.

The TMC event icons appear on the navigation map display to indicate the location and nature of a TMC event.

TMC event icons will appear on the map, even if the event does not occur on your route.
