Infrared reflective windshield
The infrared reflecting glass prevents the vehi-
cle interior from becoming too hot. It also blocks
radio waves up into the gigahertz range.
To enable operation of radio-controlled equip-
ment, e.g. toll recording systems, areas on the
windshield are permeable to radio waves :. In
these areas, you can install radio-controlled sys-
tems.
These areas can best be seen from outside the
vehicle by observing the light reflected off the
windshield.
