Behaviour of TMC and TA
You have a choice between the TMC Scan and the traffic announcement (TA) functions.
You cannot select both functions simultaneously. If you switch on TMC Scan, you
ensure that the radio will only search for stations transmitting TMC data during the
automatic search. The data relevant for your route will be used for the guidance; in
case of traffic obstructions, a detour will be suggested.
If you do not need guidance or are listening to an audio CD, yet you do not wish to go
without current traffic announcements, switch on the traffic programme function. In
that case the radio will play the traffic announcements even if it is in CD or CD changer
mode or muted.
Depending on the selected function and the station, the radio display will show the TA
or TMC status:
