Installation instructions for Android Mercedes W204 screen upgrade
The first step is removing the factory Mercedes W204 screen unit and radio/CD, then you can connect all cables and install new touch screen W204 head unit in your car.
The above photo shows you the old model with many plugs connections.
Upgraded in 2022: You just need to connect less plugs now, see below photos:
You will need to connect the white LVDS plug behind the new android screen(right plug as above) with your w204’s LVDS plug which was disconnected from the back of your factory screen.
Old model: need to check every plug with different colors carefully, the correct connections should be as following:


New model: Less plugs, clean install as below:
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.
Want to connect an aftermarket backup camera with this w204 android GPS unit? That’s easy to do that. Check a black cable with yellow RCA connector and BACK-VIDEO-IN label on it which connects to the video cable from the backup camera, see below pic:

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.
Trouble Shooting
Note: this cable is not included in the package by default, because only very few cars need it.
After installation, if you want to listen to radio and navigation sound at the same time, you can try these steps: When the unit displays original radio interface, long press the voice button from your steering wheel controls, then the screen will automatically switch to our GPS function, so that the GPS sound will come out from small speaker, and radio sound comes out from car speakers.
Switch from factory menu to new Android menu: just activate and enter into factory Aux mode, the screen will switch to new menu automatically. For new version, you can touch the screen to switch from old menu to android menu, click FM/CD icon to switch from android menu to old menu. If can not switch, you can check another solution here: How to switch W204 screen to Android menu?(note: this is just for old model with switches, new model does not have switches anymore, because CAN system can be set in factory settings for new model)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.
