Installation Guide
v1.0
GWL-9211-1
Gateway Lite emulates a CD changer and uses
CD changer controls to access offboard audio
sources like iPod and USB devices.
The best place to install the Gateway Lite D2B
maybe somewhere behind the dashboard/head
unit. Remove the car’s head unit from the
dashboard according to car manufacturer
instructions. If you do not have a CD changer in
your car, please make sure that the head unit can
control a CD changer (e.g. products light at
optical output socket of the head unit.) If not,
please refer to an official Mercedes service,
where they can easily reprogram the head unit to
enable the optical network for Gateway Lite D2B.
If you finished this step or you made sure that the
car’s D2B network can accept a CD changer or a
CD Changer exists in your car please do the
following.
(2.) Join the power harness of the Gateway Lite to
the radio.
Plug the power cable lead to the Gateway Lite
D2B.
The allocation of the #1 cable is the following:
Red: + 12V battery
Black: GND
Purple: wakeup
See the pinout of the Mercedes power harness of
different head units.
