Quick overview of how I fixed the no sound issue after installing the new Android entertainment unit/display.
Usually the “audio In” Jack is connected via a 3.5mm aux cable which is then ran down into your glove box or centre console where it’s plugged in. (For me this was into my AMI/MMI slot using the adaptor supplied with the kit)
In the end I gave up on this method and instead a much simpler method I found was to just plug the 3.5mm aux cable coming from “audio in” into the other “audio out” Jack rather than into the centre console AUX. This can be found with the bundled cables going into the display unit itself with a bunch of other cables labelled DVR, AV in, AV out etc…
Once this was done I then modified the settings under the Mercedes engineering menu
(hold red Hangup button+1+#) OR either of the town below if the above does not work.
(Hold red hangup button+2+#)
(Hold green dial button+1+#)
** Do this at your own risk, my video is for information only demonstrating how I achieved this**
Once updated and reset, you can then navigate and finalise additional Android settings.
Took me a few attempts as was not simply plug and play, ordered 2 AMI cables only to send them back, but fortunately turns out they are not needed IF You have the additional “3.5mm Audio Out” Jack.
** I’ve added a photo at the end of the video to show you how I wired it up**

You God sent!...been having No sound issue for ages.....and this worked like a charm! THANK YOU
You're welcome! Glad it helped
Thank you this video saved me I just bought the screen for my cla and no sound until I watched your video cheers 🙂
No worries, glad it worked 👍 ….hopefully you had no real issues either tucking the new larger harness back in behind!
Thank you so much for your video.
Going into the main unit admin menu and doing Disable/enable on MOST and AUX with resetting the main unit did the trick for me.
I had no sound from the android unit and I didn't want to thread an AUX cable to the AMI port in the armrest.
BTW I did try using the AMI port with the AUX the sound quality was sub par.
This way, with using the AUX cabling that connects the android unit with the head unit directly, the sound quality is the same as the original quality like from the radio or a USB from the main unit.
Thank you so much.
Agreed the AMI port quality is sub par.... AUX method all the way. Glad you sorted it!
Just came across this your video trying to fit a 10.25 android screen to my 2010 E350 NTG 4.0. I spent the best part of 4 hours wiring and unwiring the whole system, the manual tells you clearly that you need to use the Aux or the AMI, i couldnt get sound from anywhere even its own operating system nothing. I followed what you said and even the Aux position 2 and 6 in my case and the MOST set to off then with INTERNAL Speaker the Radio burst into life as did the Aux and it works perfectly now. Thank you for making such a helpful video.
Awesome glad the video helped! Such a relief once things are up and running 👏
Hi having the exact same problem will give that a try. Thanks for sharing.
Can you help I have this to fit but I have no aux or the other port in the car it’s a audio 20
Hi mate I hope you can help I only have usb in my centre console so I bought a usb to aux adaptor but still no luck
Thank you so much for this video. Really helpfull, while I cant get my sounds to work.
Two questions where did you plug in the AUX cable in the centre unit?
Second, do you know where you can buy the LVDS connector to the screen, or do you have an image of the connector wiring so I can build on myself? It was not included in my kit, otherwise I have all the same stuff. Thanks in advance for your reply!
No problem. You referring to the centre console? For my setup I had an AUX out from the harness which plugged into the AMI to AUX connector which then connects to the AMI port itself in the arms rest. Unfortunately I don’t have any pics of the connector. The smaller harness which connects to the back of the LCD screen had an AUX IN port which is usually for external audio dvds, PlayStation, tv runners etc… I connected my AUX cable into here.
I installed a unit like this in my w218 but my command knob and aux don’t work. I get a lot of static from Aux when connected can hear audio under static.
Thanks a lot for this tip. It worked very well for me. I tried connecting to the centre console and it didn’t work as well. I wonder why the vendors don’t include this as the standard connection method.
Yes putty they don’t, fortunately a workaround they works for the majority of users. Glad it helped
Hi, I've been watching a few different videos,
This password of 1314 works for me, have seen many have 190627 another combination has also been 2018 and one that used 8888. But thanks a lot for the video helped me.
Awesome, that’s good to know, seems there’s a variety of codes from manufactures, glad the video helped.
Thanks bro. You save me.
Your welcome, glad it helped 😎
Thank you 😊
You’re welcome, glad it helped
Hi, thanks for the video. I have a roadtop 10.25 android screen in an A207 2012 E250 - It was all working fine and now the aux cable makes no difference if its plugged in or not. The sound only plays via bluetooth and I've tried everything to get the aux cable to work (as the sound was much louder) but to no avail. Do you have any suggestions?
Strange, would suspect a setting has changed rather than hardware/cable failure? Failing that would replace the aux cable connection between in/out with voltmeter
hello, nice video, I did the conexion with the ami cable, but I have a buzzing noise all the time, did the noise cancel loop filter work fine for you ? I thinking the module have a problem or a bad gorund. what do you think ?
Noise loop worked perfectly for me along with adjusting the master volume level
Hi, I am curious did your calls work on your car system or did you have to install the small speaker they gave? I love the screen but they told me I need to install the small screen to take phone calls as I was not getting any sound. This feels like a pointless upgrade for me if I have to now use the cheap speaker and not the car one. The only other workaround that I can do is to select the audio source on my phone to the Mercedes Bluetooth. This could be annoying as I need to pick up and then select the source on the phone.
Nope never used any external speakers. All worked out the box for me
Hi. I tried the combination "hungup#1" but the menu that appears is completely different with some basic settings. None of these which you show is not there. Hence not the option to activate the AUX. Is there any other way to get that screen? Thanks in advance
Most users are ok with this combo to enter engineering mode, but depends on what year and version NTG your car also came with. Instead replace the “hangup” button try the “dial” green call button instead so “dial#1” or “hangup#2” hope this helps
Hey, buddy!
I appreciate the video.
Really helped me out..
One question, tho.
When I'm using Android Auto and I receive a call, then a blue call screen pops up, and then I'm unable to follow my GPS on Google Maps. Any thoughts?
Hey thanks, a blue screen? it works flawlessly with apple carplay...if youve tried adusting all the headunit settings, only other thing i could suggest is try updating latest app/os on the android phone? try another phone to see if that blue screen is trigged by the phone or actual headunit itself?
para una mercedes amg gle que procedimiento recomiendas, la pantalla android que le puse trae android 11 y el adaptador de audio es un s/pdif que se conecta al usb de la camioneta y del otro lado a un rca con entrada de audio coaxial pero no lo puedo hechar andar
Hi, didn't you have MediaInterface in your menu under Audio? Or did you disable it and if so how?
No media interface, but usb or aux… if there’s a connection to media cable then aux will auto seecr
Hey, I have a 2016 g class would something like this fit? And would mind to provide a link as to where to buy one?
Thank you
I purchased from Aliexpress, they are ALL the same units and will fit; you just need to decide which screen size and android version you prefer, took around 2 weeks to arrive. Make sure to purchase an aux noise cancelling ground loop adaptor and if Yiur car does not have reverse camera might be a good time to buy this now. Both can also be picked up from Amazon too
I'm struggling with this too. I've tried audio in to audio out behind the factory head unit and also audio out to AMI and both don't give me audio. I can get audio if I connect a pair of headphones to the audio out. So it must be a setting in the android display. My aux position is correct, it's set to manual and set correctly in the NTG menu. I can't find a way to turn off MOST though as I have a different NTG version. W204 here. Pulling my hair out!
Hrmm if you’ve got different NGT version double check you have the correct harness and wires going to correct pins… perhaps try another PIN to enter system menu that may enable some greyed out features…
hello, I have an android but I think it is version 10. whenever it enters the aux mode, it makes a small noise in the columns..... what could it be? does your android also have a small column? when i turn on my gps the sound comes out of the small speaker..... can't it come out of the car speaker? Thank you for your help.
Small noise? Have you used a ground loop noise cancellation adaptor? Have you increased the oem volume and android volume under the android settings? It should come out Yiur main car speakers if Your aux cable is correctly connected
My scroll and OEM NTG menu is lagging when I use it? Has this happened to you? everything else works for me
Nope can’t say I’ve noticed this? Not sure why it would affect the NTG menu…. Works perfectly for me
I had sound working on radio and CD etc but no sound on Bluetooth before. After doing settings as you mentioned in vid I've lost sound to radio and CD etc as well and still no bluetooth sound. I tried to reverse the settings back to what they were but still 0 sound.. please help 😢
Settings as in the changes in engineering mode/menu? When you changed back did you ensure to reboot out of the system?
I got my aux to work using the original method do you find that your aux sound quality is really poor? Any way to fix this?
Honestly had no issues, used an aux ground loop adaptor
PLEASE HELP! I have a problem with my CLA NTG4,5 mercedes because I don't have engineer mode, they show me some menu but without these options? I also don't understand where to connect the Android output to the original device, I connected via the only option AMI aux cable that came with the android device!
Strange, i believe they all have engineer mode, your pretty limited without entering this. I got rid of the AMI cable,
How's the sound quality? I've found videos and blog posts that the sound quality it not as good as the factory sound.
Sounds great, had to adjust the master volume under menu and used an photo 3.5mm adaptor to reduce any static noise.. unless your listening to this at max volume it’s exactly if not the same quality
I cant get a command settings on the new screen . I unplugged everything and plugged back in as its should be and nothing.. can't get any comand menu at all.. and no sound aswell .. did you know what can be the reason??
Thank you
Sorry not 100% sure, it should be simple case of plugging up back to oem harness, ensure all connections are seated and fully pushed in. Possibly incorrect harness depending on NTG version
I have a question.
I'm struggling to get the command unit back coz of all the cable. Can u tell me how to do it ? Thanks
See part 2 of my video, this is a common problem, it is very tight but can be done!
Hi Kevin, I have an NTG 4.0 version for a W212, I get sound but it is a very disgusting sound, I also think it’s a settings thing that I need to configure out, Radio works perfect screen works perfect but when I connect to Aux its like my speakers are a 1 watt cheap speaker sound I get from them. Any ideas? On my Merc I have the AMI to aux cable.. no direct Aux, do you think thats why it is so bad with the sound? I didn’t try connecting the aux cable from the screen to aux, i used the Aux cable directly from harness to AMI Aux.. I really need your help please. Also can you send me a link or model name number to your device. Thx man. Greetings from Germany
Yes, You need to buy an aux noise cancelling ground loop adaptor as seen at 5m 09sec can be purchased off eBay or Amazon, your 3.5mm aux cable will plug into this before connecting to headunit,
@@kevinkitho thank you very much for the reply.
Hey mate, good video, I dont get where you said you connected the audio out to the audio in on the console - there doesnt seem to be a picture uploaded to show the wiring. I have this issue right now, have a different unit to install and has the audio out cable in the cable stack. I am assuming I will need to do this bypass like yourself, but I dont know where you plug this cable into (I am assuming the radio unit itself) but where and I am assuming with the 3.5mm cable too ?? Cheers
For this headunit there is an "audio in" and "audio out" cable both 3.5" jacks. The "audio out" jack is grouped in amongst the new harness that plugs into the back of the LCD unit itself (reverse cam, video in, aux in etc) the "audio in" jack is grouped in amongst the new main harness itself that plugs into the back of the Command unit. There is no existing "audio in" jack provided with the oem harness. Between the audio in and audio out jacks I've used a ground loop adaptor (black plug that can be seen in the video) not necessary but does eliminate some of that background buzzing when volume is turned up. If you do not have an audio in with your new harness and version of headunit then this method wont work, will need to use AMI cable or AMI bluetooth cable....
My knob isn't working. Does anyone know anything to fix it. I have a A180 2014. And got the 12.3 screen NTG4,5
Your knob isn’t working?? Ensure all the clips connectors are seated correctly…
Hi the left side sprekers not working on android system but working fine with OEM radio any suggestions?
Thanks
Can’t say I’ve come across this, other than checking physical connections are 100% secure or any settings on the headunit that allow mono/Stereo or L/R speaker balance level whilst in android mode?..
I'm having the same issue as above. Did you find a fix?
Yes the cables was lose so check the cable jack or replace it
Hey my push started button is not working error message says no key detected
Have you ensured ALL cables have been reconnected, no problems for me
What brand head unit is this?
It's an aftermarket chinese branded unit
After I install the Android screen my touchpad stop working. Did I do something wrong?
I think you will need to adjust some settings under engineer mode…
niether password worked for me i bought from a different seller so mine is a bit different i messagedd them but waiitng as of now
Yes unfortunately they all have factory set passwords. Password for my unit came provided within the package. Hope you get it sorted
Unfortunately none of these steps have worked for me. I am afraid the fiber cables may have come disconnected as I was trying to push the massive harness into a place that would allow me to push the head unit in. I hate my life right now. Hahaha
Arghhh I 100% understand but dont give up, I think it took me a good couple weeks before I braved it again but I assure you it DOES fit!
I think I have narrowed down the issue with my car. I think my amplifier has gone bad. I noticed the fan on it is not spinning. I assume it spins the whole time it is powered on. Out of frustration I removed the android system and replaced it with the factory screen and still no audio so I am almost certain it’s the amp.
@@mayhemcreative1661 do you already have fix it? I have the same problem
@@TheShark1313 so I did a reset on my radio and the audio came back on. I can remember the steps to reset it but I’ll see if I can find them and let you know.
