Gateway Lite D2B 

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.
