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

Safety notice

Some navigation devices contain a GSM/GPRS module which can interfere with electrical devices such as cardiac pacemakers, hearing aids and aviation equipment.

Interference with these devices may endanger the health or life of you or others.

If your device includes a GSM/GPRS module, do not use it near unprotected electrical units or in areas where the use of mobile telephones is prohibited, such as hospitals and aircraft.

Using traffic information

If you are using an RDS-TMC receiver to view TMC traffic information on your Mazda NB1, no connections need to be made as the receiver is built into your device.

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 color of the pointers, as shown below, gives you an instant indication of the type of incident:

traffic-arrow-1      Unknown or undetermined situation.

traffic-arrow-2      Slow traffic.

traffic-arrow-3      Developing traffic jam.

traffic-arrow-4      Stationary traffic or road closure.

Taking the fastest route

Your Mazda NB1 device regularly looks for a faster route to your destination. If the traffic situation changes and a faster route is found, your device offers to replan your trip so you can use the faster route.

You can also set your device to automatically replan your trip whenever a faster route is found. To apply this setting, tap Traffic settings in the Traffic menu.

To manually find and replan the fastest route to your destination, do the following:

  1. Tap the traffic sidebar.
    Tip: If you find that tapping the sidebar opens the Main menu instead of the traffic menu, try tapping the sidebar with your finger resting on the edge of the screen.A summary of traffic on your route is shown.
  2. Tap Options.
  3. Tap Minimize delays.
    Your device searches for the fastest route to your destination.The new route may include traffic delays. You can replan the route to avoid all traffic delays, but a route which avoids all delays will usually take longer than the fastest route.
  4. Tap Done.

Minimizing delays

You can use TomTom Traffic to minimize the impact of traffic delays on your route. To minimize delays automatically, do the following:

  1. Tap Services in the Main Menu.
  2. Tap Traffic.
  3. Tap Traffic settings.
  4. Choose between always taking the faster route automatically, being asked or never changing your route.
  5. Tap Next and then Done.
  6. Tap Minimize delays.
    Your device plans the quickest route to your destination. The new route may include traffic delays and may remain the same as the original route.You can re-plan the route to avoid all delays, but this route is unlikely to be the quickest possible route.
  7. Tap Done.

Making commuting to work easier

The Home to work and Work to home buttons in the Show home-work traffic menu let you check your route to and from work with one tap of a button.
