After much research, I have come to the conclusion that without rooting the device there is no way of modifying the current audio behaviour. Even then, nothing is guaranteed.
Shamanix is probably the only person in the world whose HFP calls (when phone is paired with Android HU instead of with BMW) audio output is going to his USB DAC. My HFP audio out goes to my 3.5mm audio out socket and to the harness instead.
My DTV audio output also goes to my 3.5mm audio out socket and to the harness.

logcat samples of the relevant tags, show this:
when playing KSW music player (audio via USB DAC):
02-21 16:09:55.925 D/audio_hw_primary( 735): enable_audio_route: apply mixer and update path: compress-offload-playback usb-headphones
02-21 16:09:55.925 D/audio_route( 735): Apply path: compress-offload-playback usb-headphones

when playing KSW BT player (audio via USB DAC):
02-21 16:11:51.152 D/audio_hw_primary( 735): enable_audio_route: apply mixer and update path: deep-buffer-playback usb-headphones
02-21 16:11:51.152 D/audio_route( 735): Apply path: deep-buffer-playback usb-headphones

when making HFP call (audio via 3.5mm audio out socket and to the harness):
02-21 16:12:35.080 D/audio_hw_primary( 735): enable_audio_route: apply mixer and update path: hfp-sco headphones
02-21 16:12:35.080 D/audio_route( 735): Apply path: hfp-sco headphones

when using DTV (audio via 3.5mm audio out socket and to the harness):
02-21 16:10:17.854 I/MediaFocusControl( 1490): abandonAudioFocus() from uid/pid 1000/9289 clientId=android.media.AudioManager@924c670com.wit s.bluetooth.core.GocsdkCallbackImp$$ExternalSynthe ticLambda0@3becde9
(DTV is not even registered as an app. It is some sort of hardware call or something. No events are registered in the log at all. Only event registered at DTV initialization is the abandonAudioFocus from other audio apps)


FYI:
To check your own device,
1. connect using adb to your HU using: adb connect xxx.xxx.xxx.xxx:5555
2. run this command and watch the log on your screen in real time:
logcat -s MediaRouter:* CastMediaRouteProvider:* PSOutputManager:* atoutput.c:* AudioFlinger:* audio_hw_primary:* MediaProvider:* MediaFocusControl:* MediaSessionService:* KswSettings:* audio_hw_primary:* msm8974_platform:* hardware_info:* audio_route:* soundtrigger:* sound_trigger_platform:* sound_trigger_hw:* audio_hw_utils:* MediaResumeListener:* -v time - D -T $(echo $(date +'%s')).000

02-21 19:42:41.736 D/audio_route( 735): Apply path: hfp-sco headphones


CONCLUSION
FiiO Q3 MQA UAC2.0 routes hfp audio to 'hfp-sco headphones' - this results in audio coming from the 3.5mm audio jack on the HU.
Soundkey is identical to FiiO Q3 MQA UAC2.0 in routing.

FiiO Q3 MQA UAC1.0 is different but still no routing path 'hfp-sco usb-headphones' exists. If it did, maybe it would result in audio playback via the DAC.

Both DACs do not output any audio when DTV is activated.
DTV is like a ghost with no way to investigate what it does with the audio. (see here: https://discord.com/channels/7024375...64706299084821)

Ultimately this has to be fixed by the manufacturer who is witstech.cn I believe (business@witstech.cn). I wrote to them on 10th Feb 2024 but no reply has been received.

@Snaggle [DE] and @Keto[DE] Any chance you folks know how to switch audio from HU audio out to USB->DAC (I think within MCU, and not between OEM and HU), or prevent it from changing? Its the USB-DAC connected, incoming phone call audio not coming through speakers issue. (mic works but callers sound does not come through) ... SetMusicSource or Set Aux autoswtich or activation perhaps.?

With this version of the MCU and the firmware, as with all other firmware updates in the future, I also had no problems with BT calls and USB-dac

Yes root is required.

adb connect xxx.xxx.x.x:5555
adb root
adb connect xxx.xxx.x.x:5555
adb remount

Now you have root access to all system partitions.

You are absolutely right.
I did not know that.

>adb root
restarting adbd as root

adb connect 192.168.10.16:5555
already connected to 192.168.10.16:5555

adb remount
remount succeeded

Hello everyone,

is there actually a way to set the lines (in this case yellow and red) to the vehicle width?

[conandrum]

Shamanix / RedErik
Guys, is the 'middle speaker' connection a good thing to connect or do you advise against it? (this guide does not explain much https://hifimaxnavi.com/pages/about-...ker-connection)

Just to confirm with you:
I have a middle speaker in the car.
I do not use the OEM navigation. I only use OEM radio/music.

So with the HU connected, the purpose of this 'middle speaker connectors' is ONLY to play the HU navigation prompts on the middle speaker at all times? (ie. even when the CCC is switched over to FM/CD/DVD etc?)

Secondly:
Is it useful to enable 'FL Speaker Enable' in Factory settings? Why/Why not?

GPS & 4G Antenna
My GPS SNR is about 24 (yellow). WhatGPS antenna do you recommend for stronger reception?
Are you happy with the 4G antenna?

Carlinkit CCPA
The HU takes 38 seconds after starting the car, to enter the main menu.
If we now launch the autokit app (for carlinkit), how many seconds does it take for everything to be ready and functional?

Hallo,
do you know where or how to buy iDrive Controller Knob from Mekede brand?
i need this part, because i buy android screen for my E84 without iDrive knob, my seller in here is not responsible, i complain but he gone.
can you help me pls

Right. The speaker's operation is disrupted if you use the KSW-Toolkit. And it works relatively stably. And not with every navigation program.

This option has a default value for me. I don't use it. When activating this option on some MCUs, there may be problems with navigation program prompts through the speaker. In my opinion, this option is not compatible with every car. It is used when listening to OEM radio.

The GPS and 4G antennas work perfectly. Even in difficult conditions. If this is not enough for you, then you can connect to the OEM fin. Or use USB GNSS antennas with the ability to receive the L1 and L5 signal. And according to my observations, the quality of GPS signal reception depends on the navigation program itself.
I use https://www.topgnss.store/en-fr/coll...leo-receiver-2


When using Carplay, the data is displayed from the phone, therefore the phone antenna is used. The iPhone 14-15 has a GPS module L1 and L5

about 1 minute

If it's a lot You can enable the HU download mode in OEM mode and connect the phone from the very beginning to the OEM BT. After downloading the HU, with the necessary settings, everything will be automatically reconnected as your heart desires. And switch the video signal to android

Hi guys,i buy a new navigation and have a one question in my head

According from 1st post - CPU: Qualcomm Snapdragon 662 - 8 Core (4x 2Ghz & 4x 1.8 Ghz) - short "SD662 or M600" is it true this GT6-EUA=M600 ?

All my info about navigation:

GT6-EUA

AndroidVer: 13
BT Ver
BLINK 6125_R_2023/12/2-11:31:28

I make a 2 update`s from mega link with mega:..//GT6_KSW/EAU/ no problem.

Can i use Ksw-T-M600_OS_v x.x.x Android 13 for my platform ?

2nd question is for Factory_config.xml for this system, can i use someone, now i have only two UI`s ID7/ID8 ?

You can only use GT6_KSW update files for your unit.

The factory_config.xml should work for both version - classic KSW and GT6 KSW.

Ok, Which Factory_config to use i found for SD625 -Factory_config_BMW_A10_394.zip
For Android 10 ?

Use the latest one for A11/A12/A13 versions.

Ok, Factory-config from SD625 and SD662 is the same ?

[RedErik]

Yes and no. Yes factor_config.xml for SD625 will work on SD662. No factory_config.xml for SD662 will have a few more options if I remember correctly.

From where can i get this factory-config for 662 i read this - https://gist.github.com/kamilbrk/6cf...ory-config-xml
