So, you joined the HU audio out & the DAC audio out and plugged it into the AUX-IN?

CORRECT! I can't remember if the y splitter was 2M>1F or 1M>2F, I still haven't removed it, it's just redundant as I no longer use a DAC.


2. DAC -> 3.5mm jack -> red/black/white wires -> FAKRA pins 2/7/8 (as shown below)? (This should do the same thing - maybe I will try this tomorrow).

Your android loom will have those wires already. Not sure if you have CCC or CIC, but in my case, I did a CIC retrofit with COMBOX and didn't need to do anything to the CCC standard harness, just coding. The coding will 100% work for all audio system variants, as I've retrofitted CIC to an e61 that already had Logik7 and the coding worked and made the audio clearer as experienced in my e92 coded to Hifi. One accidental positive is that you'll no longer need to run a wire from the screen to the armrest AUX port.

On the E series to enable the AUX from the back of the CIC and not the Combox AUX you have to disable the USB media port in the armrest. I've not found any other way to have both active. It's quirk of the E generation only. The F series use the head unit AUX (I could be wrong, but this was the case on a friends F30 that we fitted a 10.1" KSW screen to with business nav).

I guess by "much louder and clearer" you mean when compared to the default HU audio output. right?

Coding aux to the headunit, I can only speculate that there is a filter of some sort built into the armrest AUX port. The difference was obvious. Between my e92 and my friend's e61 we both were immediately aware of the difference in sound, my friend who knows a massive deal about car audio noticed it. If I was to speculate, could it be the shorter run of wires? Is it filtering or AUX voltage differences the two coding options? I don't know. But the difference was 100% obvious on E series cars that I've coded like this.



Did you experience any interference/noise from the HU into the splitter/joiner?
From my experience the HU audio out has some noticeable white-noise in the audio output. However, when I plugged both the DAC output wire and the HU output wire, into a mini mixer (I posted 2 weeks ago) the white noise disappears. (HU on its own = noise)

I've moved on from using the y-splitter, but I can't say that I had any issues. My friend's e61, I've not had any reports from him of interference, but a ground isolator would work just as well as a splitter.

If yours is Logik7 or Individual Audio, the Helix DSP and HEC are a complicated install due to the MOST amplifier in those systems. It's not a drop in upgrade to be honest for any of the factory BMW audio systems, but way easier with 676 hifi and a little bit more involved for BASE but not too terrible.

But for reference I have:
Helix DSP Mini MK2
https://www.audiotec-fischer.de/en/h...s/dsp-mini-mk2

Hi-Res USB HEC for MDSP MK2 (They're specific because the faceplate comes with the HEC card)
https://www.audiotec-fischer.de/en/h...-usb-interface


HU audio -> CIC AUX
and in parallel
HU USB -> Helix USB HEX -> ??? (How do the signals mix?)


662 Screen > CIC AUX for calls, parking beeps, alarm bongs > High level input on the HELIX DSP

In parallel

662 screen USB port> 5m USB cable > Hi-Res USB HEC on the Helix DSP

The screen treats the Hi-Res USB HEC module the same as a DAC.

The digital connection requires either a Commander or Director to control Volume, sub level, rear fill etc... I have a Commander because the Director is 2.5x the cost.

Commander:
https://www.audiotec-fischer.de/en/b...ries/conductor

Director:
https://www.audiotec-fischer.de/en/b...remote-control

Audio mixing, channel time alignment, conversion all taken care of by the DSP and then sent to my amplifiers. So to answer your question... the DSP mixes the two separate signals.

I will try to draw a diagram of this and attach it. EDIT: DIAGRAM ATTACHED



Also, what about the low output volume from the HU BT phone calls and other audio? How did you overcome that?

I used to have to turn up the AUX volume on the CIC (armrest AUX), after coding to the AUX on the CIC, I set the headunit AUX volume to halfway and forgot about it.

I had a huge problem with the screens inbuilt bluetooth, if you were navigating in an area you don't know and a call came through, you were locked to the call screen till the call was over. I never overcame this issue but did set the bluetooth on the screen to car bluetooth and installed the extra speaker to mitigate till an update fixed this.


I know what you mean!!!
I am still working on my setup. Even this afternoon!

My car has been a work in progress for 6 years... It never gets old

All answers in BOLD. Any other questions that the answers have triggered ask away, I'll do my best to clarify. One last addition, my system sounds better than L7 so I'd say it was worth the mega spend, but if you already have L7 this isn't what I would consider money well spent.

Are you talking about the Android HU BT calling app (where you pair your phone)?
If so, yes, whenever you get a call, you cannot flip over to another app until the call is over, by default!
But, you can always go to the app properties and remove the permission to 'display over other apps'. I did test it and it can even do split screen. I did not test to see what happens when you get an incoming call though. Check it out.

I'll take a look! This has been bugging me since I purchased the screen.

Let's say you go on holiday abroad for a couple of weeks and leave the Q3 in the car without switching it off. When you come back, the Q3 will obviously be discharged.
When you start the car, will the Q3 start working normally?...
...or will it need to be charged for a few hours, and switched OFF & ON, before it starts working?

Look at this review on Amazon:

2.0 out of 5 stars The battery is garbage.

The sound I get from the DAC is what I wanted when I purchased it, however the internal battery seems to be garbage. If I fully charge the battery, but don’t use it for a couple days, it will be dead and I can’t use it until it’s charged again. This was apparent from the first charge, however it was confirmed after charging it a second time. This DAC is brand new and shouldn’t be having these issues.

... There is one thing I don't like and it's the otg protocal and apple. Iphone won't charge de Dac. So no battery, no party. But at least, if you use it on pc, it will charge via the cablem, and once charged, will switch to the usb-c or usb-a power. It won't run cycles on the battery. ...

No problems with the battery. Turn on constant charging. When the HU is turned on, even with the battery completely drained, the USB-Dac will automatically turn on and work. The instructions have a description of the modes. If this is not done, in a different mode, there may be problems with sound (shutdown) when charging is activated on the USB-Dac.

I tried this today, and while it did work once in a call the touch inputs on the screen are disabled. Why on earth is the Bluetooth app written this way.

I'm gonna go back to using car Bluetooth (Combox) to take calls, at least this way I can still have control of the screen.

[moskito99]

Im on A12 KSW with SD662 12.3" (the typical Mekede/Navifly). Usually I use ID7 Launcher but when using regular KSW Launcher I opened up BT by accident, since then I cannot get rid of the autostart of teh BT app. Very annoying.even closing all apps, then opening 20 or 30 other apps and using system for 30 minutes....after restart BT app again opened up...and again and again..I dont get rid of it..

Did I miss how to resolve this? Anything else I can do? I read something to open BT app from KSW launcher and then just go back from there to main screen of ksw launcher....will this resolve the issue? Anything else i can try ton ight when being back home?
THANKS!

But at least you can see the screen now, e.g. for google maps, and you can still end the call by pressing the phone button?!

Being "stuck" in the phone call screen was a major downside for me the whole time....only saw this "solution" by accident just now, because of my post about BT App is auto starting after each bootup and so far I could not get rid of that app autostarting..:-(

try clearing the cache and data of the KswPlauncher and CenterService(this under system applications) and restart HU.

My video & music apps were auto loading just before the HD icon was shown in the upper right tray area. It got resolved by reloading my factory config file.

Guys, when I press the 'voice command' button on the steering wheel, I get both the car's assistant and the google assistant answering at the same time.
Is it possible to get only one of them? I want google assistant only?

I resolved this by coding the car. I removed Sa620 from vehicle order/Fahrzeugauftrag of my BMW e60. You might also need to code SVS nicht_aktiv in ECU CAPPL (or whatever ECU is relevant for car assisstant)

It was not so easy, but worked now. Even factory reset STILL opened BT app after bootup...just like your example...before tried as well the original xml, delete data from apps and services etc...

Then when I did some call via BT, it was gone after next bootup and did not come back yet again :-)

conandrum you still didn't answer what you need my permission for. You showed me a video of some animation that I have nothing to do with, so I'm really confused. I do understand what you are asking me for.

So can we confirm that loading the factory_config.xml helped to reset it?


Also, if you are familiar with coding, can you help me with 'RADIO MUTE'?
I want to mute CCC audio using a wire (in many cars there is a 'amp mute' pin that can be grounded to mute the audio). Can I mute my CCC (2008) using such a method?
I tried to do it by grounding pin#10 (X13812 socket) on the back of the CCC, but nothing happened.

Can you check please and tell me if I should connect my mute wire to another device (e.g. the amp)?

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?)

When I removed my middle speaker, and compared its plug with the plugs labeled 'middle speaker' on the harness, they are not compatible. My harness has 2 such wires (possibly for 2 external speakers) blue and white as shown in the photos posted previously. So I wrapped them with fabric tape on the harness and am not using them.

'FL Speaker Enable': enabled

I tested today on the road. With navigation running, I switch over to FM on the CCC, but I cannot hear any voice prompts.
Come back to AUX and I can hear the prompts.

FYI:
'Aux auto switching': Harman
'AUX switching mode': Manual (with Auto it switches to CD or other mode randomly, so I do not use it)

No...it did not help...the xml was one of many things, none helped. After all that even factory reset did not help...on fresh unit BT still opened up on bootup several times...issue was gone when I added my phone again in BT app and made 2 calls....dont know why....but this what I did.

I dont know anything these cables.

I can't, sorry. All I know is that it connects to the ULF/MULF module, but completely omitted in the documentation on how it works.
