etc.)
Different years of Mercedes Benz vehicles are equipped with different types of
the UHI interface system. MB-3 is designed to work with different type of
Comand systems via the software dip switch at the back of the unit.
The factory default setting has the both dip switches 1&2 at the “
ON
” position
(see the illustration below) and this software setting is designed to work with
Audio 20/Audio 50/COMAND APS NTG1 and NTG2 types of head units
Newer vehicles such as W204, W212, some of the GLK and W207 Coupe
which comes with a newer type of UHI/MHI Comand system (NTG 4) that
requires different type of software to work with. Therefore, before inserting
MB-3 into the NTG 4 Comand system you will need to switch to the right
software before MB-3 can work without any problem. To switch to the NTG 4
software:
1. Remove the rubber from the software switch at the back of MB-3.
2. Switch both software switches 1&2 to the off position (see the illustration
below)
Now you are ready to insert MB-3 into the UHI connector of a NTG 4 vehicle.
