External GPS antenna
This second optional GPS antenna makes it possible to receive the
signals of satellites better (e. g. in the case of vehicles with a
metallized windscreen).
1. The antenna should be pointing upwards.
2. Push the plug of the external GPS antenna into the opening
provided for it at the rear side of your device (see page 13, o).
TMC (Traffic Message Channel)
The Traffic Message Channel (TMC) is a digital radio data ser-
vice that functions in a similar way to RDS and is used to transmit
disruptions to traffic to a suitable reception device.
The traffic information is continuously transmitted across FM.
The user is less dependent on the half-hourly broadcast traffic
information, because the signal is continuously transmitted. Apart
from this, important information, as in the case of people driving
on the wrong side of the road for example, can be passed on im-
mediately.
The transmission is planned for the whole of Europe and is al-
ready offered by radio transmitters in many countries. The preci-
sion of the TMC messages can deviate greatly according to the
country.
