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.

1. User a special installation tool to remove the central air vents.
   
   
2. Unplug the cables behind the air vents, then you can take out the air vent.
   
3. Remove 4 screws to take out the screen unit and radio/cd system.
   
4. Take out the factory screen unit, unplug cables behind.
   
   
5. Take out the radio and cd system, unplug cables behind.
   
6.  So factory screen and radio has been removed and the next step is installing the new W204 Android head unit. Here are some pictures showing you how to connect new cables.
   
   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:
   

   

7. Where to put the main unit control box?
   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.
8. Want to connect an aftermarket backup camera with this w204 android GPS unit? That’s easy to do that, there’s a green cable with 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.

   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

9. This step is optional and rarely necessary. If there’s no sound after installation from Android music or video playing, but have sound from your radio and CD, you need to enter into factory aux mode to activate aux mode, if still no sound after you have already activated the factory aux mode(this rarely happens with only 1% possibilities according to our experience before), then you will need to check the factory aux wires from the plug behind the CD, and compare them with our aux wires(red, white and black wires in a group) from our new plug, make sure they are matched, if not, then you can move the factory aux wires to match the position of our new aux wires, or you can connect the factory aux wires directly with our aux wires, this is the first solution.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.

10. 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.
11. 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.
