Hi all,
I bought a PX5 radio marked TOOPAI. The Android version installed is 10. The internal microphone has a very strange behaviour.
The issue with the microphone is that the sound is very bad. If I try to use the mic app from Android to test my voice, the gain meter goes out of range and the voice is all very bad static...
If I reboot the unit the problem is fixed, What can it be?
The unit does not shutdown completely when I switch off the car. It goes into a sort of sleep mode and when I switch on the car again (even the next day) the units starts immediately and the microphone issue is back again.
Thanks to everyone that will help!
No one with ideas? Thanks!
I have exactly the same problem also with a PX5 unit. I don't suppose you had any luck?
Im currently dealing with the people I bought it form trying to sort it. Just to post what has been tried and not worked so far.
Internal and external mic have the same problem so switching does not help
I updated the firmware on the unit that was supplied by the seller and still no luck
I have recorded the audio with and without the problem and sent it to seller. They seem to be having some difficulty playing the MP3 but im hoping we can work out what the problem is.

These systems are well known for their mic troubles and I have taken this up with the manufacturer. There is a post that I have seen somewhere in this forum that details a hardware fix. From what I have gathered, anyone brave enough to attempt and has accomplished this fix has not reported any issues; great for the electricians out there.
I do work in the computer industry, but identifying electrical components and soldering is not something I am too confident with. The manufacturer did however, send me an updated update.img file in response to my mic issues. I've installed this and it made some improvement, but nothing so significant that I have actually started using the mic. It also has a new wallpaper and noticed that the default apps have been updated, but not sure how?
Anyway, I've just had a bright idea! I've tried improving the mic by using various bluetooth mics, various external mics that plugin into the mic jack, using the internal mic and manufacturer software update. All make very little difference, but has anyone actually tried using a USB mic?
I don't have one to hand and don't really want to buy one if this doesn't solve the issue. Would drivers/android recognising the usb device be an issue? Hoping someone has had a go at trying this out or can try it out if thay have a usb mic?
Shame no one replied on this one. Did you end up trying a USB mic solution and did it work out for you?
Yeah... Haven't tried it yet as don't want to buy one if it doesn't work. Your reply to this thread would have bumped it back to the top so may still get a response Im hoping
According to this link http://liliputing.com/2012/09/using-skype-on-an-mk802-android-4-0-mini-pc.html, a microsoft lifecam vx-700 with built-in microphone was found to be working on some android devices. The question is whether our firmware would work too. And whether there would be a way to simply disable the built-in input and only route the external usb sound in. It all feels like its probably too much to ask....
OK so I tried a cheap usb webcam with built in microphone to see if it would make a difference. The webcam seems to be working fine for video, was instantly recognized by android and showed video, but sound is still the horrible mess coming from the internal mic. I doubt that a dedicated USB mic would be any different.
Thanks for checking... you saved me some time at least.
Could it be when using an internal mic + external at the same time that can cause this kind of trouble? That is what it seems when i read around forums.
have a look at this, maybe it helps:

I simply cut the internal red wire to mic and installed external mic again and the problems have disappeared. I have been told there is a slight echo but that may be fixed by changing the BT firmware from default.
I think the mic location on the HU is excellent and we don't really need to route an external mic somewhere else. How about just trying to desoldier the old one and try to locate a high quality one and soldier a new one ?
Fortunately I am lucky and my internal mic works great.

Lucky you, though to be fair without an external mic my internal worked, just not very well. I have read somewhere that soldering to the internal connections had issues but not sure why, it cant hurt to try can it?

Shouldn't be a tough solder job.
Just make sure to use a solder sucker to remove old mic and you should be fine.
Guys,
I have the same problem with my android car navigation system.
I have a Note 4 and an android car navigation system in my car (with built in wifi and Bluetooth (BT)). The microphone of the car navigation system has a very low quality, it is almost not working/usable. I would like to pair my phone to the car system in BT but would like to disable the built- in microphone of the android car system and use the note 4's microphone by default and hear the sound of the person who is talking to me on the car speakers.
Is this possible? How? Do I need to use third party apps ?
Many thanks in advance
So frustrating... Anyone have a fix yet?
Android head unit mic barely picking up.
Why have they not fixed this issue?
So frustrating. Got everything all hooked up and straightened out except the daggum mic. I just bought this android head unit (9.0) and the person on the other end of the phone call can't hear me. So I plugged in the external and same. They can barely here me when I am screaming into it.
I have got to get this fixed.
Anyone found a solution yet???
Find out how to get into the engineering menu of your HU, there you can adjust the mic gain. Also have a look at this thread for other ideas.
did you fix it?

I improved the level of my mic built-in with th MTK enginerring app. hardware test and changing mic volumen in normal mode, headset mode and loudspeaker mode, but it is not enough when engine is working. I will try to solder and external mic to the pads of mic built-in. I think that it is problem of software filtering because when engine is off, sounds doesn't rattle, the volumen is not to high but the comunication is steady, but when i start the engine, conversation gets cuts. maybe engine sound is interfering with the mic built-in mic. I will update progresions.
8227L YT9216BJ Head Unit
even my above car android unit has mic problem. it does not recognize the voice commands unless spoken very close to the mic, which is not practical
Also, Bluetooth calls are intermittently heard (with Airtel). But when switched to JIO simcard, works fine.
Please can anyone support with a solution on both the issues
[email protected]
In short for helping anyone that has the same problem
I have a Bosion D6 android (android 10 version – 4 gb ram 64 storage, 8-core) head unit on my Ford Focus mk2.
Everything was perfect expect the microphone, even after I installed the external mic that came with it, the sound was poor and my listeners’ complaint that the quality of the conversation was not very good.
Read tons of stuff here and elsewhere so I decided to spend some money (around 20€) and bought a Sony microphone XA-MC10 to replace the Chinese original (since I have read some good reviews and you can find it in your local market also)
The difference was more than noticeable and everyone now listen to me perfect. i test it myslef through the sound recorder app and it seems like going from say 64kbits/s to 146kbits/s or more.
I don't want to open another thread because the problem is similar.
When I connect with iphone carplay, the interlocutor often hears me jerky, I tried both internal microphone and external also cutting the internal one to exclude it but nothing.
Using the application "microphone amplifier" and applying the filters instead it feels perfectly, but obviously every time it should start and set, so very boring.
Tried to use MTK Engineering mode to change the mic volume, but it doesn't solve completely.
Anyone have any ideas to try?
Thank you in advance
Did anyone ever find a solution to sounding really quiet to the person your calling? Cheers
Hi all.
I stumbled upon these forum by googling my issue. So far I haven't found any answers to my problems, so hoping for some help from the great people on here.
I have recently installed a seicane 10.1 android head unit into my jeep wrangler.
It appears to have a few little issues like audio is automatically somewhat louder on start up ...... but my main issue is
Only the radio app has sound.... no other apps have sound.
All speakers are working correctly with the radio app. Canbus setting is correct. But no sound output from the other apps.
If anyone has experienced this and can shed some light on it for me I would greatly appreciate it.
Thanks.
If it is a new unit,I guess you car may has factory amp,you need to connect the head unit amp harness to your car amp harness.
If the unit used for several months,then other apps no sound,I guess the main board is broken.
It is better for you to contact the seller for help.
May be a shot in the dark, but you might have hooked the amp wire up to the 'powered antenna' wire by mistake. If you tune to a radio station, that wire will get power and you will hear the sound, but if you are on a different app, that wire will not get power and you will not hear sound.
The amp wire coming from the radio will always have power and will work on all apps, and they are both blue and easy to confuse.
Pklains advice wprked for me.
The remote wire is black on the back of my unit. I accidentally hooked up blue antenna wire so it only powered amp when radio app was on.
I was NOT wiring it up incorrectly.
It was a software fault. I since got a replacement from the manufacturer (took 3 long months) since installing the replacement it worked perfectly.
hi ... same thing happened to me. Check your system. If your speaker lines is going through any amp, bridge, crossover or whatnot then do not supply CAR'S signal wire from ANDROIDS radio antenna signal wire (the android unit's antenna wire has +12v only when radio is on) - test audio by supplying 12v to your CAR'S signal wire. Simple yet it took me some time to figure things out. I hope this helps out someone who has the same problem.
Also it is not advisable to connect ANDROID amplified output to VEHICLES AMP - should be pre-amp from ANDROID to AMP or use LINE OUTPUT CONVERTERS or DIY (search speaker level to line level adapter ... a simple voltage divider worked for me) make sure you know car amps impedance before anything else ( industry standard is 10k )
I have the same problem with my PX6. The unit worked for a few months, but all of a sudden I only get sound from the FM radio.
Any advice?

did you find a solution to this? I sometimes get this, the only way for me to fix it is by doing a hard restart by pressing powerbutton for 15seconds

Do you get this issue all the time or is it random?
for me it's random, i have to force restart the unit to get sound working on stuff that's not radio/beeps.

I get it all the time, but it started with a lot of "static noice" from the speakers. That went away if I rebooted the device. The unit worked again for a few minutes and the problem with the noice was back. One day it just went totally silent except beep and FM radio

I had to desolder the amplifier (TDA7851L) and replace it with a new one. Not easy, but everything works for me now
I don't see my exact problem, which is very similar to everyone here. I get sound from the Radio app - but if I use the Radio app, I lose sound everywhere else. I retain the ability to use the Radio for sound. This also happens upon a reset, as if it starts the radio first or something - but the app doesn't need to be started for that to be a problem. This started upon initial installation.
Fun thing: If I power off the car (battery still connected of course), wait a few minutes, then try stuff, I get sound everywhere. Until I use the Radio app, of course. Naturally it decides to reboot when it feels like it, so this is annoying.
I have an Eunavi HU. The same heppened to me after upgrading the firmware with a file provided by manufacturer. No sound, only on radio. After few messages with the manufacturer here is the solution that worked: Factory settings->DSP settings->ARM Audio Input Selection-> check Analog Input. Hope this solution will help someone.
HelloI have this problem with my ts10 hu
Hi. After changing Canbus setting in my android head unit, I haven't any sound in all app and radio in my HU. Please help me.
I got fed up with not being able to understand a word when my wife is driving, with her old Android 4.4.4 head unit. 4 years ago I tried all of the known microphone mods, externalizing the internal microphone and splitting the microphone between the Bluetooth and the internal microphone. It never really helped.
During Aliexpress big sale recently, I got her a px6 (non-MTCD) head unit. The screen and everything else seems to work fine, but the noise when she is talking via Bluetooth is just unbearable. I have tried a few different external microphones, and it sounds like a tornado is blowing in the background. I refuse to start cutting mics again and am just going to return it.
Are there any units out there that have decent sound cancellation? Or is that too much to ask of a chinese radio?
I have been having a serious issue with my head unit ever since I got it. Well, actually, not me, but everyone who I talk to on my phone with it over bluetooth, in particular when my DVR is recording the dashcam. When the built-in DVR is recording the dashcam, it keeps making a loud buzz sound every 5 seconds to the receiving end of the call. That is, I don't hear it, but anyone I'm talking to on the other end of the call does. It is very loud and irritating, to such a degree that I have to turn off the DVR every time I'm in a call. Obviously, this shouldn't happen. Additionally, I find the same thing happens when making a call with Skype installed on the radio, which wouldn't be using bluetooth at that point, so it seems somehow either the dashcam itself (it is not the DVR software, I tried another software that did the same thing) or a hardware issue is creating noise on the line-in or mic in the sound system that goes out to the other end of the call. I've tried support from the "manufacturer", but they aren't much use and I don't intend to send the unit back to China and wait to get it back for 4 or 5 months. I suspect it isn't likely to be the dashcam, so for some reason there seems to be feedback on the USB line to the sound module.
So, I'd appreciate any ideas here. I've also tried numerous other DVR apps, but it seems that pretty much none of them function correctly with the USB dashcam that came with the radio. I don't know if it's an issue with the specific camera or that it's a USB interface for the camera. So, I'd appreciate any experience anyone can offer to resolve this.
Other than these issues, I've got it working the way I want. I installed a cooling fan on the PX5 CPU. I need to put a capacitor in parallel with it still as I think it's causing the LCD to flicker slightly. It came with Android 8, so I installed Android 9 on it. Upgraded the MCU. I also replaced the plain WIFI antenna wire with a plugin port so I can connect a better wifi antenna. I found an app that allows me to force a normal reboot instead of the pseudo-reboot it does with the power button because Android sometimes needs an actual real reboot.
There are some really annoying quirks about the radio too that if anyone knows how to change I'd be very grateful. For one, the Accessibility Services keep getting disabled when the radio is shutdown with the car. It seems to be a memory function built into the device as it doesn't happen with a real normal reboot. Also, the wifi sometimes gets shut off, I assume for the same reason. And the lack of security really really bugs me.
That's not an issue it's a feature I guess they didn't want to dedicate a PCB layer to route analog signals I even wonder if they have a dedicated layer for power. Anyway the problem is they run analog lines next to/under digital lines and no ground plane to isolate the 2. There is a mic mod thread that addresses those issues if you're interested.
Maybe just installing an external mic would be sufficient if your HU already has a connector for it. As for your other issue, check the factory settings menu there should be a setting to restore the unit to previous state on reboot. Sorry I can't remember the exact name of it.

I have an external mic. It doesn't help. Thanks for pointing me in the direction of the mic mod. It's probably what I've been looking for. As for the factory settings, I don't seem to have an option to restore the unit previous state in my factory settings.
Replaced my ageing Parrot android headunit today with a Xtrons TSD100L unit.
Works fine, plays all sources fine, but when switching from one source to another is seems to turn off its audio output briefly causing amplifier to make a horrible pop sound.
I've checked everything and cant figure what issue may be - i thought it was possibly the power trigger to the amp being switched off each time, but its definitely staying powered during each switch of source.
Anyone seen/heard similar issues ?
Cheers !!
