Hello. I have Witson head unit. I have a problem with the microphone, there is a very big noise and the voice is quiet. I found pictures on thsi forum(i only save jpg) how to modify the microphone on the radio witson.
I spread out my unit and saw that I do not have a separate bluetooth plate, and that my PCB is all other than on photos. Has anyone repaired a microphone in this unit, or knows how to do it?

Hi,
one year ago I bought and installed this android head unit from aliexpress for my Suzuki Liana:
Android system 2.5D 9 Inch car multimedia player for Suzuki LIANA 2006 2007 2008 2009 2010-2013 car radio vehicle gps navigation
Some stats: Android 8.1, CPU: A7 1.3GHz, GPU: Mali-400, RAM 1GB, ROM 16GB, Radio Chip: NXP 6851, Amplifier: AC 7315 4*45W
Everything (even including they steering wheel buttons) works fine only the internal microphone is virtually useless. I read that some head units have really cheap and weird cable-ling going through the Bluetooth module. It also just be the cars vibrations transmitted in the head unit casing. Anyhow, the microphone as it is, and thereby any google assistant functions, are non functional. Unfortunately the head unit does not have any jack for an external microphone.
I saw that several people redo the wiring and solder an external microphone in the head unit. I would like to avoid this, since I am not that familiar with electronics and I am not keen on disassembling my dashboard (again).
I read that some people with similar problems connected a external USB sound card to their radio to get around this. I bought an external card and a microphone on amazon (Sabrent USB External Soundcard and augustcoco Microphone 3.5 mm External Microphone). I tried it on both USB ports of the head unit but nothing changed.
I have 2 questions:
1) Does anyone has an idea to make an external microphone on this head unit work?
2) If the USB soundcard would work, can I only use its input (microphone) and keep the output sound from the head unit? I do not want to change the output, since I can not reroute it back from the soundcard to the head unit.
Thank you for your support!
