When you connect the RDS-TMC Traffic Receiver to your TomTom device, a message is shown in the top right corner of the screen and the Traffic bar is shown on the right-hand side of the screen.
Once an FM channel with RDS-TMC traffic information has been found, the circle at the top of the Traffic bar turns green. When information about traffic problems on your route is received, the problems are shown in the Traffic bar. Information about problems that are not on your route can be reached by tapping Browse map in the TomTom Traffic menu.
