Mercedes Benz W204 Screen Upgrade – How to Switch Android Screen and Factory Menu
Most Mercedes Benz C-Class W204 comes with a 5.8″ small screen above the radio and air vents in the dashboard, some are with a large 7 inch screen. No matter which screen size your w204 has, you can upgrade the W204 screen with an aftermarket Android screen. The factory W204 radio keeps working after upgrade, just replaces the factory screen for installation.
The W204 screen upgrade with OEM looking, with both systems, old system and new Android system.
If you want to check the features, specifications and price of the 8″ w204 screen upgrade android unit, just check on this page:
It’s upgraded with latest Android system now. You don’t need to set switches anymore, the software can do that for you, for a factory small screen, we will set it to NTG4.0 400×240 for you in factory settings. For a w204 with factory 7″ large screen, we will set it to NTG4.0 800×480 resolution for you.
Due to the different resolution from factory screen, the switches settings from the main unit are different. Normally for Mercedes Benz W204 with factory small screen, the settings for switches of the main unit should be 2, 4 on, 1, 3, 5 are OFF.
About these switches:
- Only turn it on when you test it with external 12V power, if you install the W204 Android screen in car, please remember to turn 1 to OFF before you connect the plugs.
- If your car has small screen, you need to turn 2 to ON, so the Android screen can display factory menus normally. While if your W204 has 7 inch screen, 2 should be OFF.
- Always should be OFF for 3, it’s the setting for another model, not for W204 model.
- Regularly, if you turn 4 ON, you are able to switch from factory menu to Android menu after you activate and enter into factory aux mode. After you enter into aux mode, but the screen does not switch to Android menu, you can turn 4 to OFF, when the screen displays aux mode, then you can try to long press the BACK button or C button, so the screen will switch to Android menu.
- If your car comes with factory reverse camera, then you can turn 5 to ON, so the screen will display factory camera image while reversing. If you need to install an aftermarket back up camera, then you need to keep the 5 to OFF.
If you order the Mercedes W204 Android head unit from us, we will confirm your car information with you and set the correct switches for your car before the shipment, so that you don’t need to set it again.
Overall, after installed the W204 screen upgrade, you can switch between the factory menu and new Android menu.
Mercedes W204 with factory small screen:
- Correct settings: 2 ON, 4 ON
- Factory menu switches to Android menu: just activate and enter into factory aux mode, the screen will switch automatically, if not, then turn OFF 4, then long press BACK button or C button to switch.
Mercedes W204 with factory 7 inch large screen:
- Correct settings: 1, 2, 3, 4, 5 ALL OFF
- Switch to Android menu: long press BACK or C button(Regularly just long press BACK should be ok, but we also met a w204 should long press the C button which is a little different.)
Latest Update: the latest version does not need to set switches anymore, it’s compatible with both factory small 5.8″ screen and large 7 inch screen, the screen resolution can be set in settings now, not need to set the switches anymore.

Solution For No Sound After Installed BMW E60 Android Head Unit
Are you trying to install an aftermarket BMW E60 Android head unit but no sound comes out from music or video playing while testing? The sound from factory radio and CD player works well, just no sound from Android screen. Don’t worry, if you follow instructions provided in this post, you can get sound with this solution.
How To Find Out The Exact Problem?
Firstly you should know that the sound from Android screen transfers to car speakers through original aux mode, so if there’s no sound, the first thing you need to check is your aux, does your aux work well now? You can use a aux cable to connect your phone with the aux jack in the armrest or below the radio unit, then play music with your phone, and check if the sound from your phone comes out from car speakers, if yes, that means your aux works now.
The next step is checking Aux wires from original wiring harness behind the factory radio and CD. Make sure your aux wires match the new aux wires in the same position. Few BMW E60 comes with aux wires in different position or without aux wires from the plug behind the radio. You can check our aux wires from our plug as below:
Our aux wires are with red, white, and black color, 3 wires in a group, you can see below picture:
Compare your plug with our new plug to check the 3 aux wires in the same position. If your aux wires are not matched, or your plug does not have aux wires, then you can try our solutions.
This picture shows you the original wiring diagram from BMW E60 E61 radio module M-ASK and CCC.
Check connector B, pin#2 is AUX Left audio, pin#7 is AUX right audio, pin#8 is AUX ground.
So you can check if your aux wires are in the position as above. If not, you can move them to the same position as above. While if there’s no aux wires from your plug as below:

If there’s no sound after installation of BMW E60 Android head unit, here are 2 solutions for you.
First solution:
This is easier, you can buy a aux adapter cable from us. So you can connect it directly with your aux jack in the armrest or at the rear of armrest, which means our unit connects to your aux directly without modifying wires.
Second solution:
Since you have already known how does the sound work, and know you will need to connect your aux with our aux wires, you can also splice our 3 aux wires from the blue plug and connect them with a aux cable.
Splice red, white and black wires, connect them with a cable as below. Then connect that cable to your aux jack.
Feedback from one of our customers in Norway:
I sort thing out. Must mods the black, white and red plug from your unit harness into a aux cable. Then connect its to my aux in inn the armrest. I got sound in that way.
For customers in Dublin, Northern California, USA, close to San Francisco, we have a recommended shop for you. They have already tried and proved the second solution successfully.
What to do if my BMW e60 not have AUX?
We have another solution for BMW e60 does not come with AUX function. You can purchase a small amplifier from us together with the e60 Android head unit. This small amplifier option can transfer the sound from our Android e60 unit to your 4 car door speakers, you can check it as below:
However, you should make sure your BMW e60 does not have fiber optic amplifier.
Because this small amplifier does not work with factory fiber optic amplifier.
In order to check if your e60 has fiber optic amp, you can try to take out the factory radio/CD unit, and check the plug behind, if there are 8 speaker wires from your plug as below, that means your e60 does not have fiber optic amplifier, that’s great, so your e60 without AUX can use our small amplifier to transfer the sound.
