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.
- User a special installation tool to remove the central air vents.
- Unplug the cables behind the air vents, then you can take out the air vent.
- Remove 4 screws to take out the screen unit and radio/cd system.
- Take out the factory screen unit, unplug cables behind.
- Take out the radio and cd system, unplug cables behind.
- 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:
- 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. - 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
- 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. - 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.

Hello,
I have the fault 7″ Display remove and install your system. But no sound from Android Display. Second, if I push FM/CD on Android, the Display switch black, more not. If i push on original radio CD or FM I can heare the source, but nothing on Display shows. It is a C-Class 2008. Also, in HeadScreen I have the funktion “beginn connecting AUX” selected, the procedure never ends. The “to do nothing” shows over 40min. What can i do?
Thanks alot
July 9, 2021 @ 7:07 am
By searching your name or email, i did not find your order with us, your unit should be different from ours, our unit does not have this “beginn connecting AUX” menu. Please contact your seller for after-sales service.

January 5, 2018 @ 4:52 am

January 28, 2018 @ 5:51 pm

My unit has been plugged in the car, The problem is not yet able to play DVD and the gps sound is still out along with the radio sound. Incidentally my car does not have a voice button, what should I do?
May 22, 2018 @ 10:07 am
If there’s not a voice button from steering wheel controls, gps sound can not come out from the small speaker which included in the package. As for DVD function, if you did not choose DVD player option, there’s no DVD function available, since you can keep using factory CD player and you can also play videos through USB or SD, so DVD function is not necessary.
July 30, 2018 @ 5:21 pm
There is instruction manual / getting started PDF in the app section of unit. Can this be emailed to me so that I can print it and read how to use the functions of this
August 20, 2018 @ 3:21 am
You can print this page directly.

Hi,
I have got no sound from new unit. My old radio sound is ok.
What do I need to do with the 2 male phono plugs coming from the centre of the main wiring harness ?
Many thanks.
January 7, 2019 @ 4:41 am
You can check if your aux wires matches the new ones, if not, then you can connect your aux wires with the new aux wires directly, red/black/white color in a group. Or use our Aux adapter cable to connect your aux port to get sound.
January 7, 2019 @ 8:22 pm
Hi,
In which socket on the android control unit, does your Aux adapter cable, plug into, and how many pins does it have ?
Many thanks.
January 8, 2019 @ 7:06 am
You can check the blue socket plugged into the android control unit, the Aux adapter cable also comes with blue plug to connect the same connector.
January 8, 2019 @ 4:03 pm
Hi,
How much does your Aux adapter cable cost + cheapest delivery cost (No rush) ? Is it on eBay ?
Why no sound from small speaker/buzzer, even from the Navigation App (IGO version 9), which comes with this unit?
My car has FACTORY radar, parking assist sensors, but no reversing camera, Audio 50, with simple DVD Navigation.
Many thanks.
February 26, 2019 @ 3:38 am
The cable is US$15, shipping cost is US$10 by hongkong post, if you need you can contact us to order one, but we can not guarantee if it works with your unit or not as you did not buy the Android w204 unit from us.
July 6, 2019 @ 9:34 am
The original Mercedes navi has a cap above it that slid upwards when press on the button. Can I still use the cap with your system..?
July 14, 2019 @ 2:12 am
Before installing the new w204 Android head unit, this cap will be removed, because our w204 screen unit is larger than the original screen.
December 16, 2019 @ 9:55 pm
Will it work with my IPhone 11? Does it support apple car play? Tks
December 17, 2019 @ 2:02 am
Yes, it supports iPhone 11, it supports Apple Carplay.
January 9, 2020 @ 11:04 pm
there are five buttons for setting. they are numbered from one to five. can you tell me what functions each number has? you can do it up and down. Thank you
January 25, 2020 @ 10:21 am
This unit has been upgraded and it does not have 5 buttons for settings anymore. So this don’t need to be set anymore.
January 22, 2020 @ 1:59 am
Hello, the sound is the same as the original sound before installation of the screen? Or do we have any problem? Also I can put back camera on this screen?
And where from can I buy this
January 25, 2020 @ 10:11 am
Hello, the sound transfers to car speakers through your aux mode, so you can check your aux sound quality. It can support factory and aftermarket back up camera.
January 29, 2020 @ 11:38 am
Where does the phone plug in? Is there a USB connector somewhere?
January 30, 2020 @ 7:57 am
There’s a long USB cable included.
April 4, 2020 @ 4:44 am
Hi, I am wondering where the small speaker which you supply is connected to. I feel it must be obvious but I can’t see where.
April 10, 2020 @ 6:05 am
Small speaker with a small white plug connects to the main unit control box now. If you check carefully of all plugs from the main unit, you can easily find it, because all plugs are different.
April 27, 2020 @ 8:57 pm
Hi, how i can switch between the two designs?
April 28, 2020 @ 10:56 am
Yes, this can be set in factory settings.
