Introduction

Connections

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.

Finally connect each cable according to the
numbers in the first picture. Lead away the cables
where the devices will be placed. (E.g the glove
compartment or the center console).

Optical Installation

Mercedes cars can have two different layouts of
optical network. That is why the D2B optical kit
contains two different optical harnesses (labels
on them will help). The #22 belongs to the cars
with Comand (made by Bosch) head units and
#21 to the others.(3. and 4.) Unplug the
connector of the optical harness from the head
unit and connect it to the #21/22 socket of the
optical harness of the Ice>Link Gateway 500. If
there is no factory fitted optical cable connected
to the Head Unit, you should connect the given
#23 optical loop to the spare female connector of
the #22 optical cable.
