Hey,
I purchased an Android head unit PX30 for rav4. An external microphone has been set up on the left side of my head (20cm distance ).
People have difficulty hearing me. For example 5-10 seconds they can hear me well but after that sometimes they can hear its own echo or they are picking "wind" sounds.
Any advice?

I'm hoping I can get some answers here about this. I have a Kenwood bluetooth head unit in my truck. I like to use S Voice to text, play music and other stuff without touching the phone while driving.
My issue is if Bluetooth is on and if I say Hi Galaxy then say Play Music it acts if it doesn't hear me. If I turn off bluetooth connection between the Note 3 and head unit then say Hi Galaxy then play music it hears me fine and plays music.
I was thinking maybe the mic pickup wasn't cranked up enough to hear me on the head unit. On my head unit I have a setting for Mic Gain. Is this suppose to increase sensitivity for the mic to hear more clearly? It was set to 0 but I cranked it up to +8 and then tried it again with no result.
On the sound bars, below the microphone button on the S Voice, if sound is picked up it will move up. It never moved so it's not hearing me. Now if I banged on the top of my dash with my fist the sound bars move and shows it is picking up sound but it has to be a loud bang to a point I feel like I'm gonna cracked my dash if I keep on doing that.
I can't tell if the issue is my head unit or the phone itself. Bluetooth volume is cranked to the max on the phone.
Do bluetooth head units have built in microphones? I would think they do otherwise it would be a pointless head unit and pointless to have call button functions on the head unit.
Anybody have suggestions?

Nevermind. After looking over the manual to my head unit I somehow skimmed over the microphone part even though it came with the head unit. I have no clue why I didn't attach it and understand the point for it was to communicate hands free or else the person would not hear me.
Had to take the unit out and install it and it works perfectly now.

I've bought my head unit in aliexpress.
At the last week, I updated the firmware with MTCD_XRC_V2.58_B, and the system now is beeping sound every 5/6 seconds.
The brand is GS, and my car is a corolla e120.
I made a video that demonstrates the problem, is in Yandex.
yadi.sk/d/KEcq-Z8b3MX238
I don't input any command, and the beep occurs even that I do nothing.
When I scroll down the status bar, after beep sound, it returns without any input.
Can anyone help me?
Thanks a lot
Hello everyone.
I have a problem with my new android head unit. It is an MTCD PX3 octacore with 2 GB of RAM Android 7.1.2 in a Toyota Corolla.
The problem is that I have a deficiency in sound. The sound when playing a CD (DVD) is perfect and high, but on the rest of the audio inputs (mainly player and radio) it sounds lower and with interference or noise.
This noise increases as volume increases and becomes annoying.
I thought it would have to be a problem of volume levels, but checking the factory settings (Voice menu) putting everything to the maximum I still have the annoying interference.
I start to be a little desperate because I do not know what to do, I hope some of you can help me.
Thank you very much in advance.
Hi, im a newbie here.
I just buy an aftermarket secondhand chinese headunit and already put it in the car.
When my car only using battery, the head unit function flawlessly. But after i put it in the ignition, the headunit restart and all the media become very low sound almost mute. The only sound coming out from the speaker is 'beep' if i touch the screen.
Right now, to make it work I am pushing reset button or restart my car after 15 minutes.
What should i do to make it working? Is it hardware problem or android problem?
My headunit:
Model number: car audio
Android version: 5.1.1
Built no:ALPS.LD_kk1.MP10V1.6
Mcu:sm92a.1.170427.v1.1-jly-b3
Sorry for bad english

Hi Guys,
A while back, I purchased the T10 unit from Srnubi. It worked perfectly for day 1. All speakers working, subwoofer was loud, everything was great. I came back to the car the next day and there was 0 subwoofer! Nothing was changed, everything normal so I started trouble shooting and I testing turning the bass up on the DSP to max, only then I could very faintly hear the Sub working. I figured I would try to reset the unit in hopes that it would work but now I have a factory android head unit with no running software (except the android auto and carplay software) and still next to no subwoofer output. This lead me to believe that the subwoofer out RCA is not working. I tested all RCA's and they're all very faint (I'm running the speakers from an amp which is connected to the head units speaker wire as the chanels). Has anyone had this issue before and is there a way I can fix the RCA Output without opening up the headunit and looking for faults on the board? And how do I install the firmware that Srnubi has sent through? They've completely stopped replying to me and didn't provide any instruction, worst part is they waited until my 15 days was over to stop replying and now I can't raise a dispute on AliExpress.
Any help would be much appreciated!
Cheers!

DSP output to subwoofer has probably burned (regulator voltage chip inside on board), must be replaced.
