Understanding How The TrafficKit Works
Please read the following statements before using the TrafficKit.
1. You can enable and disable Traffic event categories. By default, all categories are enabled.
2. Selected Traffic events will either alert and/or re-route you depending on the operating
mode.
3. All selected event categories will be displayed on the map screen in the form of traffic event
icons.
4. If you are not routing to a destination, the RDS function will only display Traffic events on
the map screen.
RDS-Traffic Operating Modes
Traffic events that impact your route can be processed in one of the following two modes:
Re-routing Mode. (Default) Traffic events affecting your route will trigger the receiver to automatically
calculate a new route, if a faster alternative route is available.
Alert Mode. Traffic events affecting your route will be reported to you in the form of warning
messages.
