Installation instructions for Android Mercedes-Benz C-Class W204 navigation head unit
The first step is removing the factory Mercedes-Benz W204 screen unit and radio/CD, then you can connect all cables and install new touch screen W204 head unit in your car.
Click the above picture for larger view.You need to connect the white CAR-LVDS plug with your LVDS plug behind your factory screen.
Secondly, please check every plug with different colors carefully, the correct connections should be as following:
There are 2 square big plugs to connect your CD and factory wiring harness, see below picture:

Important! If there are fiber optic cables from factory wiring harness, you need to move them to our new plug at the same position as below:
You can put the main unit box in the glove box as below.
If you don’t know how to detach the glove box, you can check this video on how to remove the glove box for Mercedes W204.
And there’s trigger line which should connect 12V+ reverse light, see below pic:
Besides, you should get the power for the camera with 12V reverse light(not from our 12V power), so after you put in reverse gear, the camera can get power and automatically display rear view images on screen.
Note: If you have connected the camera correctly, but still no signal or the display is not stable, that’s because the voltage from your car reverse light is not stable, we have a solution, you can connect a relay to power the camera. A professional mechanic should know how to connect the relay for the camera easily. Here’s a document with clear photos for you to check how to connect the camera for Mercedes W204 and how to connect a relay, you can download it here
The second solution is by using a aux-adapter audio cable from us to connect our main unit and your 3.5 mm aux port directly in the glove box to get the factory aux working. You can check this cable as below:

Note: this cable is not included in the package by default, because only very few cars need it.
If there’s no sound from car radio or CD playing, you need to check the fiber optic cable plug which connected to our new plug as below:
Solution: Please turn off your car and the unit, then you can disconnect the entire square plug from your CD, then re-connect the fiber optic plug with our CD plug, make sure it’s well connected. We had one customer the first time installed but there’s no sound from radio, after he checked and re-connected the fiber optic plug the sound issue solved.
After installation if your old factory OEM menus does not display normally, don’t worry, you can contact us we will tell you how to set it correct in settings. Because there are 2 different OEM screens from Mercedes-Benz W204, one is with factory small 5″ screen, the other is with factory large 7″ screen, the screen resolution is different.
If you still have a question while installing, please take some photos for us to check all cables and plugs connections and send to us via email sales@dvdgpsnav.com, our technicians would be glad to assist you. You can also contact us on Facebook:
