Mercedes W204 interface
Installation manual
This Mercedes W204‐specific interface can insert RGB navigation video or CVBS video into Mercedes W204 screens:
C200, C230,screen[5 –inch screen which has 280*100 resolution],
C280, GLK,SLK: [7 inch 800*480 resolution].
It also has the following advantages:
Compatible with Mercedes C ‐5inch screen and 7‐inch.[Selected by DIP8]
All installation is plug and play.
Two display mode: one full screen mode and one high resolution mode for
5‐inch screen.
Original keys can be used to control navi very conveniently.
ACC is generated by the interface box[ACC=12V when screen is working]
1. Interface connection:
RGB‐NAVI
AV1/2
CAM‐AV
CAN/POWER
The monitor’s video
connector is inserted
onto the daughter
board in this way.
3 keys for color
tuning.

The daughter board can be 1.8 meter away from the interface box, it accepts the car LVDS input plug, and send out the
LVDS output plug to monitor.
4Pin CAN connection:
GLK/SLK special considerations:
GLK’s ground is more fragile behind the monitor, when interface is installed, noise
will happen and hurt the image quality when the horn is pressed, the image may
jump at the same time. In this case:
Please connect the separate extra GND black wire to the screw behind the monitor,
then GLK’s image is perfect.
The connectors behind the monitor:
[there are 2 connectors behind the monitor, one is video‐LVDS, the other is
power and CAN, it is not necessary to take out the CD and make
modifications there.]

[note: CAN wrong connection is not hurting device, the LED will be blinking when connected correctly。]
CAN box’s 4P should be connected
to car’s 8P connector[behind the
monitor].
The 6P connector ‘s signal definition [6P output from CAN box]
YELLOW: 12V battery power
RED=ACC:when screen is On this wire goes to 12V.
BLACK:Ground for chassis。
GREEN:reverse wire[=12V]。
white: switch signal when =12V.[max 25V]
GRAY: specific control signal from the CAN box.
GLK: Use one screw to connect
GND of the daughter board for
better noise immunity.
The interface box can be installed
inside the foot‐stand of the front
passenger. The navigation unit can
also be placed here. The CAN wire
and LVDS wire are long
enough.[1.8Meters]
There are two connectors:
10P video connector to monitor,8P CAN/power
connector.
The video is inserted on that 10P connector, the
CAN/POWER are sharing the 8P connector.

2. Control NAVI with original keys :
The Grey wire of the RGB connector is IR ouput, it should be connected to the IR sensor input of the navigation
unit.
The Gray wire of the AV input is IR output for DVD changer. OSD will shown
when the user push the knob right/left side, so the user can control DVD.
