On vehicles with panorama roof with
power tilt/sliding panel, installing an
antenna to the front or rear roof area is not
permitted.
On the rear fenders, it is recommended to
position the antenna on the side of the
vehicle closest to the center of the road.
Use the Technical Specification ISO/TS
21609 when retrofitting RF transmitters
(Road Vehicles - EMC guidelines for installa-
tion of aftermarket radio frequency transmit-
ting equipment). Observe the legal require-
ments for retrofittings.
If your vehicle has installations for two-way
radio equipment, use the power supply or
antenna connections intended for use with
the basic wiring. Be sure to observe the man-
ufacturer's additional instructions when
installing.
Deviations with respect to wavebands, maxi-
mum transmission outputs or antenna posi-
tions must be approved by Mercedes-Benz.
The maximum transmission output (PEAK) at
the base of the antenna must not exceed the
following values:
