Dynamic navigation
Dynamic navigation is possible if the navigation system is con-
nected to a TMC source. The TMC data are sent to the naviga-
tion system. The navigation system analyses the information it-
self and takes the traffic flow, traffic congestion length and legal
speed limit into account when working out a new time-optimised
route.
GALA
The automatic volume adjustment feature adjust the volume to
suit the speed at which you are travelling. As your speed in-
creases, so too does the level of noise inside the vehicle. The
navigation system therefore adjusts the volume of the voice out-
put automatically. You can set sensitivity of this adjustment fea-
ture.
GPS
The Global Positioning System is a system of satellites devel-
oped by the United States ministry of defence for determining
your position anywhere in the world. Under ideal circumstances
the system's precision is below 10 m.

Gyro
The gyro (gyroscope) is integrated in the navigation system. It is
used for determining changes in direction when taking turnings
or driving along bends.
Positioning
To ensure that the navigation system provides the driving rec-
ommendations at the right time, the position of the vehicle on
the road network must be determined very precisely. Sensors
detect the route being travelled along, the direction of travel and
changes in direction. The position of the vehicle is tracked by
way of a GPS satellite receiver. The information from these sen-
sors is constantly compared to the course that the road takes
according to the digital map on the CD-ROM.
TMC
The Traffic Message Channel is a digital traffic information data
channel that is used for broadcasting consistently up-to-date data
on the current traffic situation.
