About RDS-TMC
The Traffic Message Channel (TMC), also known as RDS-TMC, transmits traffic information as a
radio signal and is available free of charge in many countries.
TMC is not a TomTom Service, but is available when using the TomTom RDS-TMC Traffic
Receiver.
Note: TomTom is not responsible for the availability or quality of traffic information provided by
the Traffic Message Channel.
The Traffic Message Channel (TMC) is not available in all countries. To check the availability of
TMC services in your country, go to tomtom.com/5826.
Using traffic information
If you are using an RDS-TMC receiver to view TMC traffic information on your TomTom Start,
connect the TomTom RDS-TMC Traffic Receiver to the USB connector on your Start.
The traffic sidebar is shown on the right side of the Driving view. The sidebar informs you about
traffic delays while you drive, using glowing dots to show you where each traffic incident is
located on your route.
The top of the traffic sidebar represents your destination and shows the
total time delay due to traffic jams and other incidents on your route.
The central section of the traffic sidebar shows individual traffic incidents in
the order they occur on your route.
The bottom of the traffic sidebar represents your current location and
shows the distance to the next incident on your route.
To make the traffic sidebar more readable some incidents may not be shown. These incidents will
always be of minor importance and only cause short delays.
The colour of the pointers, as shown below, gives you an instant indication of the type of incident:
Unknown or undetermined situation.
Slow traffic.
