@Support Dasaita il problema c'è sia con microfono esterno collegato e sia con microfono esterno scollegato.
Io credo che entrambi i microfoni lavorano insieme. Sono entrambi attivi

Hello, I had to remove the 13.3 screen to make some connections behind the double din. After putting things back together the screen does not respond touch. I pressed the reset but still no response. Any idea what I need to do? My unit is the vivid 10 universal 13.3PX6 4g+64g
Also, are there updates for this unit? I purchased in in 2022.
@Fred Traylor Please kindly try to use a mouse to calibrate the touch screen under the video instruction below.

@Support Dasaita Yes, thank you! The mouse worked but I had to do a factory hard reset. All is well now! Are there any updates for this unit? I've had it nearly 3 years, I haven't done any updates at all.
I've also been having this issue for a few months now, the only fix I've seen anyone report is to take apart the unit and desolder the internal mic, which seems crazy.

@Fred Traylor
Hello.
We'd like to remind that the update operation involves the potential risks.
For this reason, we suggest that you can keep the current version to use if the unit can work normally.
@Support Dasaita On my G13 the call quality is poor and after a few tests I've noticed that the microphone used is the internal one, even though I have the external one connected. Some videos on YouTube show the option to choose which microphone to use in the settings, but I can't find that option on mine. I don't know if this is the solution to the poor call quality, but it should be an improvement.
Order SP-DA6575 and purchase date January 10, 2025. 
@Milton Nascimento Hi，

1.Download the documents ①&② through the link on your computer/laptop.
(Do not rename and Unzip the file)

(Tick the option"Wipe data and format flash")
3.MCU updated GO：Settings>System>MCU updates.
@Milton Nascimento i video che avrai visto saranno antecedenti agli ultimi aggiornamenti. Proprio dopo gli ultimi due nemmeno sul mio g12 non è più possibile trovare la voce per attivare o disattivare il MIC esterno dato che vorrei fare delle prove perché in chiamata l'interlocutore non sente bene la mia voce
OK, I've been trying different things and still having poor microphone quality on phone calls. I replaced the microphone itself and located it close to the original microphone location. Still poor quality. I tested it both through carplay and through the Head unit software. Same issues.
Can you confirm that I have the latest software versions?
