is stationary.
You must observe the legal requirements for
the country in which you are currently driving
when operating mobile communication
equipment.
Please remember, a navigation system does
not supply information on the load-bearing
capacity of bridges or the overhead clearance
of underpasses. The driver remains responsi-
ble for safety at all times.
You and others can suffer health-related dam-
age through electromagnetic radiation. By
using an exterior antenna, a possible health
risk caused by electromagnetic fields, as dis-
cussed in scientific circles, is taken into
account. Only have the exterior antenna
installed by a qualified specialist workshop.
You will find information on retrofitting elec-
trical or electronic equipment in the “Vehicle
electronics” section (Y page 318).Installation for PND mobile navigation
