Where did you put your external Mic? I put it in top left corner of windshield on the soft part of interior as I have found that if I put it on sun visor it picks vibrations and people do not hear me. Also BT sound on the phone is set to MAX and third thing I have found that in some cases that when I have call immediately after phone and HU gets connected that call is garbled and calling back fixes the quality.

---------- Post added at 04:23 ---------- Previous post was at 04:01 ----------

Well that is the progress :)

It is possible that car adapter is bad/wrong, but I still think it is the harness issue.

I'll see if I can get friends Jetta second Cable to see the connections and compare with yours.

Thing you should need to do is to take pictures of all backs of connectors and white one for canbus so that it is clearly seen where each cable goes and where it is plugged. Then do same thing for Dashboard plug so that in the end I can create pin out comparison and tie them to the connector and make schematics.

Regarding your Car Model it should be fairly easy to decode VIN number (either in beside windshield or in inner side of hood) and get the production date and model of car https://www.google.com/search?q=decode+vw+vin+number So that I can get wire schematics for Car stereo. Also you have not pictured sticker on OEM Stereo where is pinout/connector description and Stereo model so that I can search for its service manual (usually it is easier to find that than Car electronic schematic).

I know it is bit of work but I hope it will worth. For me it was worth as I ordered Nissan HU and put it in Suzuki with no issues at all. And please be detailed in taking pictures as much as possible, better to have more than needed than those where I can't see where cable goes from and where to.

Be quick as when we finally crack Oreo Update I'll have much less time to help.

Hello Peka,

One more time thank you for your time / help !

I've added more pictures to my shared folder :

https://drive.google.com/open?id=1OGxuIC8J6O-1c22Vmx2uX9CbFIofJoRg

Whats new :

- 2 pictures of dashboard with OEM HU

- picture of vehicule ID references with VAG options + text file with the options decoded

- 10 pictures of OEM HU (8 of the back, 1 of the top, 1 of the bottom)

I hope this will help. Unfortunately there is no diagram on the HU. I've search on google for "l40vw2" but I don't think I've find the good ones ...

I've found the user manual : https://fccid.io/ANATEL/00741-14-09...a-L40VW2/ECC715BB-646A-43B2-AD33-8462A20405D5 But I don't think it will help a lot :(

Hope that the picture would be enough.

Have a nice day.

Hi

I still have issues dasaita PX5 Octa chip, which i have listed below, could you please help ?

1) The dab+ sound still judders whenever you leave the app. Its been doing this since i purchased the unit and i can see that lots of other people who own the unit keep having the same issue.

2) The album covers keep work withing the music app intermittently work

3) The steering wheel controls cannot select any downloaded apps and when in other apps you cannot skip tracks etc (e.g. spotify)

This is known limitation. You might use MTCDTools by [MENTION=7621504]f1x[/MENTION] to bind additional actions, application launches etc. to steering wheel buttons. Also don't forget about a donation :).

2) It depends on how you copied the files on device and/or app that synced the files to SDCard/USBDrive. I'll write about that as SOON™ as time permits, but from what I know Spotify was one of teh apps known that do not work.

3) Not all apps support External media Commands and not all apps register itself to Android for Media Controls reception. Will cover that in more details SOON™ as an app that I use support that option so when in Forground or in background and no other Media registered app is in foreground it reacts to commands.

Much clear now, it is more possible that CanBus is wrong for your car.

I'm attaching Two pictures of what we know about connectors. you would need to confirm if I'm right for cabling. There is still some questionable two Cables, to check if they are external USBPower so that you can charge the phone on the USB Jack.

Otherwise most of the rest are clear and now you can send them all the info about harness and confirmation that with Cable B you can powerup the unit and confirmed working so problem is either in CanBus or Harness.

Additionally:

1) I noticed that your Car only have Front Speakers so I'll attach you a picture what you need to buy in order to add back speakers and lay down cables for them.

2) Your Car speakers are 25W so in order to have full quality and not get them fried, you will need to replace the speakers for better ones. I personally have 4 Pioneer TS-A1686R from https://www.pioneerelectronics.com/PUSA/Car/Speakers/A-Series and I'm more than satisfies, maybe I'll add sub, but not ATM

A video to remove pins from Iso connector that you will and put in OEM to connect rear speakers.

Hello Peke,

Thanks again for your time :)

Hum yes I can connect my phone on the USB and it's charging.

I can't send that to the seller on AliExpress since he has blacklisted me ..... :-|

So I've provided all this informations to Dasaita Hot Audio. They reply me every two days and they are willing to help I think :) I presume that they will soon comfirm whats wrong. Just a clue : when I send them the canbus adaptater picture they replied nothing but "is it from your seller ? ". So maybe they already know whats wrong but just want to be sure before telling me.

I'll check that carefully once I have the HU working well, but I can't play the video, neither open it on youtube. Can you provide the link maybe ?

Anyway I'll keep you updated with the Dasaita replies !

Have a nice day.
[MTCD Android Head Units General] PekeMM:
Can you please post link to Device and seller in PM maybe purchase ID, I'll see to report them for such behavior. You should also do the same.

They are usually very willing to cooperate (one of the rare tech support that do), We prepared all the info, have you sent them also sticker from Cable A and Cable B so that they know what cables you received? If your HU is working on desk it should work in the car after harness/canbus mess is fixed. Meantime you can prepare rest so that you can fully enjoy the sound :)

I've been in touch with support team on AliExpress a LOOOOT. Too much time wasted with them ... They don't understand anything (maybe they don't want anyway), and you must repeat everytime you go in chat the same things ... Everytime i'm in chat with the support team it lasts at least 1h ... It is very annoying.

Since I've sent the guy the video where I show the HU does not work, he blacklisted me so I can't even send him updates. It was 3 weeks ago. Before that he wasnt replying to me for maybe at least 10 days anyway.

So every 3 or so I contact AliExpress team, and I repeat the whole story everytime. They just tell me how sorry they are, that now it'll be ok and so on ... But since 1 month nothing moves.

They have sent at least 3 reminders to the seller but he does not even reply to them. So since 1 month : nothing new.

It is just a waste of time unfortunately.

They have absolutely everything. Maybe too much ;)

Great, thanks :)

[MTCD Android Head Units General] SkyBeam2048:
In the Bluetooth echo fix thread it's only about MD725 at the moment since those Bluetooth modules seam to be heavily affected. In this thread also [MENTION=7621504]f1x[/MENTION] stated that he would have a look at other modules as well as long as users could provide logs. He also tried to h elp with SD968 issues and spent time on investigations. Even though some users don't seem to have any issues with SD968 some obviously do.

Unfortunately [MENTION=7621504]f1x[/MENTION] found that the architecture for SD968 module software/driver is entirely different and the core functionality is not done in Android code run in ART environment but in binary code in a native library where he does not have the source code for it. This basically renders it impossible to do changes on the code unless the source code is provided.

Also in this thread it was advised to upgrade to one of the latest ROMs (referring to the latest HA ROM) as in changelog some changes regarding SD968 module were listed. So you might want to try the latest and/or different ROM.

You can of course also open a thread about your SD968 issues. Maybe other users can help you or report their issues too. But don't expect someone to be able to fix the code as the issues are likely within a binary which cannot be modified as "easy" as the bytecode for MD725 was modified by [MENTION=7621504]f1x[/MENTION].

[MTCD Android Head Units General] truitor:
I don't really think that it will be useful because I had so much time wasted with AliExpress team for nothing. To be honest I think they are aware of problems with some sellers, but I think that they don't care. The only thing that I don't understand is why they pay support team when they are several hours with angry customers :)

But anyway I can send you my order ID no problem !

They are just useless. They can't do anything useful. The only thing they can do is send email to the seller to say "hello seller, can you please check your messages". And that's all ... They can't escalade when there is a problem, and they cant report bad behavior for a seller. So they are useless.

Anyway Dasaita have replied in email. They wanted me to check something : try to connect the whole system in the car but "force" 12V on ACC in order to boot, and then check canbus informations.

So I've done that. I've removed the red wire on canbus to put it on the yellow +12V of harness. So the HU boots, but I have no information coming back from the canbus.

You can find the pictures in my shared folder : https://drive.google.com/open?id=1OGxuIC8J6O-1c22Vmx2uX9CbFIofJoRg

There are 4 pictures for 20180117 : the first one to show the red wire on 12V so nothing wonderful. The second one shows that no information for the car is retrieved. And the 2 others are for software versions.

Do you think that I can test canbus adapter in another way ? With another software maybe on the HU ? Or just by open / close the cars doors ... ?

Did you always experienced this issue? Or only after some kind of upgrade?

Check that all wires are correctly installed...it seems you have the acc (ignition) loose and lose and get contact continuously ...when headunit detects no acc it enters into sleep (with the shutting down message)...But if suddenly recovers ignition...it goes back (but some apps and services are killed)

But it's strange, bacause I could leave it running on the homescreen for hours and no "shutdown", then I open Headunit reloaded or some other app (not all apps trigger it though) and it starts looping the shutdown bull****.

This add more to my previous statement about power usage being the reason.

1. I'm not sure if overheating can trigger power down without notification (had seen this on Nexus 7 2012 few times)?
