I m not sure, I do know that some VW and Audi systems have only 2 set of speakers that are amplified but exactly how they work I couldnt say, I d try the conversion box and see what happens.

What trouble is it that you're having with your unit? I've got an a3 with Bose mine is a 59 reg and there's always some interference on the speakers and I can't get the dab to work properly. I used to have an android 4.4 unit on a 57 reg a3 which didn't have Bose and everything on it worked perfect.

Hello,

Has anyone found a solution so that the Bluetooth (MD725) does not turn off after 2 or 3 days?

Everything else works fine, I have no problem with WiFi or other ...

It's just a bit annoying to have to reset twice a week to reactivate the Bluettooth.

Thank you
[MTCD Android Head Units General] ab1702:
Just wondered if anyone had any advice on where to place a ground loop isolator that I've purchased.

Ive had an android 4.4 unit before with a different A3 that didn't have Bose and everything worked perfect on that unit.

I've now got an A3 with Bose and it is causing interference with the unit. You can hear it through the speakers, the sound quality isn't very good on a2dp and the dab signal isn't as good as it was on my last a3 that didn't have Bose.

The instructions say to place the isolator on the acc cable before it gets to the head unit. There is also a trigger cable for the Bose amp, would that have anything to do with it or is the ACC cable the best place to put it?

Thanks

What type of unit do you have?

Have you tried updating the mcu and the ROM?
[MTCD Android Head Units General] mikejclark:
The problem is that without the conversion box, my rear speakers don't work. The head unit being A3 specific I thought would mean it would work without any modifications. I do know that my rears are amplified though, so I'm assuming the box I've used from my old head unit (not android) is a high to low signal converter, I'd just prefer to not have to use it

---------- Post added at 02:10 PM ---------- Previous post was at 02:03 PM ----------

You must have it connected wrong, your unit should come with everything you need in the box. Take it out and start again without the conversion box. Also make sure none of the prongs are bent over or anything on the connectors.

Have you tried fading the speakers to the rear to see if that fetches any sound through?

You're probably right, but I tried everything you are suggesting and more, and couldn't figure it out. I'm looking at one of these units now as my mtcb is becoming frustratingly slow

It does not work with the factory radio unless you press the sensor parking button on the car or you place the reverse.

So, no, the front sensors arent active all the time. It works the same as the origin factory settings.
[MTCD Android Head Units General] ab1702:
Ah right I didn't know you had an mtcb unit, I think I know what your problem is then.

Do what I said earlier so take your unit out and start again just with the loom that came with your mtcb unit and don't put in the other thing that you're using from your old unit.

Then go onto the amplifier and fade your speakers towards the back of the car, then go into factory settings with pin code 126 and you should see some options across the top of which one of them should be voice. You need to increase the figures in there and then apply them and then exit and then it will say your unit needs to reboot. This will increase the volume the unit gives out which should kick your rear speakers into action providing the unit is wired up correctly.

I did a thread about it on the audisport.net forum as a lot of people were complaining about rear speakers not working or being very quiet and saying you need to buy all sorts of different looms and adaptors when really it is just a case of changing some settings. If you go over onto that forum the post is called 'android head unit rear speaker fix, no extra parts needed!' I included screen shots on there etc.

Why do you think we have to add anything to a list?

The list is made by manufacturers of px5 not sellers...

Use the app "Apkextractor" to extract the launcher from your current ROM, flash the new ROM, then (after rooting) install root explorer or similar, copy your old launcher into system/priv app, make a folder named the same as your old launcher and put the old launcher apk into it, change permissions of both to the same as the launcher/launcher folder in your new ROM and install the launcher.

To sort out your slow MTCB unit you have 2 options, either do the 2Gb RAM upgrade (see the 3 threads on it in the MTCB forums) and/or install [MENTION=6041319]dsa8310[/MENTION]'s or [MENTION=5228031]Johny DJ[/MENTION]'s microg ROMs.

We need a picture of your settings/about screen so we can see your MCU, then we can identify your unit.

Youre right, but having a list of sellers in the first post does add confusion. :)

Today I tried playing with the factory settings. My settings are for canbus: Manufacter All, type None, Rudder left. So nothing special for my Ford Focus Mk2 (september 2008). Then I tried a manufacturer and a type and then I noticed that in my software there was an app call Sync. I opened it, but could not do anything with it.

Does anybody know which type of canbus I should select? It is a european car. When I select the correct canbus, do I then see the door opening etc.? Thanks.

Has anyone figured out a way to get your Contacts sync'ed to the head unit? I know Google Contacts flat out doesn't work (seems caught between thinking there is no account connected OR that there is an account connected). I've loaded some third party Contact apps, eg: True Contacts and Contacts+, but they don't seem get pick up the contacts from Google either.

Another issue: Here WeGo doesn't work for me. It runs but before it can get to loading maps it crashes.

Wasnt aware that [MENTION=3590033]Malaysk[/MENTION] was doing ROMs for Ownice units, but youre in the wrong forum if you have one, this forum is for MTCD units. Your MCU suggests that you have a GS unit, not an Ownice, please post a screenshot of your settings/about device screen.

How do I prevent apps from getting killed at shutting down?

I tried the PreferApp (or something?) and selected the 3 apps I want and pressed save. However, only one app is saved, the other two are blank after opening the app again.

Are there other apps that do this? I would prefer this instead of using something like automate or xposed edge, because those relaunch the apps right? I want my HU to resume where I left, not launch the same actions everytime. I'm on V4 btw.
[MTCD Android Head Units General] javlada:
Bose321> Just a few posts back I mentioned Graser Dasaita Tool which can di exactly that.

I sorted out most of my problems using Tasker and this tool. Now I have these 3 remaining:

1) After the radio wakes up, the music player plays for a few seconds and then stops because the SD card is unmounted. Any idea what should I do? Because I use my own player Muzika, I could probably implement a workaround in it, but a general solution would be better.

2) As I already mentioned, if I press the RADIO button and the radio is already playing in background instead of only taking it to the front, it also switches to the next set of presets. I tried to remap the RADIO button using MTCDTools but it didn't help.

3) So far I didn't find any solution for automatic brightness based on sunrise/sunset time.
[MTCD Android Head Units General] Bose321:
Cheers, I'll give that a try. Do I just install the APK? I also read something about a xposed module? Or is it automatically installed that?
[MTCD Android Head Units General] javlada:
Part of the Graser Dasaita Tool needs Xposed Framework. I'm not sure if the app white list needs it or not. I use it on Malaysk ROM where Xposed is already preinstalled.

I'm using the V4 ROM, so I have it installed as well. I'll try to install it today and see if it does what I want. Otherwise I'll have to use Automate I think.

Hi

Do you know what MCU version I should use with px5 DVD radio in my Mazda CX-9 2013 GT with Bose ?

I have huge problems with this radio:

MCU version: MTCD_KLD_V2.54e_1

Build number:

px5-userdebug 6.0.1 MXC89L user.hct.20170617.171922 test-keys

There is KLD version, but the problems are with wheel keys (I can programm only one key, not all keys) and the rear camera doesn't work (I used of course 12V to 6V converter).

There are a lot of MCU versions, but what version is in CX-9 ?

I spoke with China seller, but they know nothing about it.

Thanks.

DD
[MTCD Android Head Units General] typos1:
You can use ANY KLD MCU, or you can read [MENTION=4974080]marchnz[/MENTION]'s Cross Compatibole MCU thread and change the MCU to another MTCD manufacturer.

Also check out the Dasaita RK3368/PX5 threads (unfortunately there are, confusingly, 4 or 5 RK3368/PX5 threads open - you should be be reading ALL of them if you have an octacore unit), [MENTION=744370]ikerg[/MENTION] and another user have CX-9s and they were discussing SWC just a few days ago.
[MTCD Android Head Units General] ikerg:
You have to use the most recent MCU file compatible with your manufacturer (KLD)

Do you have can bus box installed? Which one? Which option is configured into your head unit under factory settings for the can bus?

Even not needed for swc buttons retaining you will need it for reverse camera triggering.

The reverse signal is hard coded and the can bus will decode into a resistive signal

If no can bus you can alternatively get the signal from the reverse lights

If you are using a can bus box supplied by the head unit manufacturer , you don't need any 12v to 6v conversor, as it is included into the can bus (at least on mine - number 14 on factory settings: Mazda cx5 made by Simple)

If you are using can bus usually all the buttons are hard coded mapped and they can't be remapped by the SWC learning app.

If not using any can bus...you must ensure that key1 and key2 wires are properly connected into the Mazda adapter like this picture

I am still battling with my KLD MTCD unit fitted in my Mazda 6 2008 (Bose system) I have now got the DAB working after receiving an app from the seller on Aliexpress and ditching the cheap screen aerial. The app works most of the time but it appears that when I start the car I have to go to another app and then back to the DAB app for it to work. Once working it is great. I have installed a roof DAB / GPS aerial http://www.dabonwheels.co.uk/Kinetic_DRA-6005_GPS_FM-AM_DAB_car_aerial.html. I have always used their aerials over the years and they have always been very good for reception. I have also fitted a ground loop noise isolator. I have tried this on both the permanent live and switched live. This has improved the background noise a little but not totally. When using sat nav it is noticeable and annoying. So I have 2 remaining issues. Firstly I'm not sure the canbus is working correctly. When the head unit starts up there is a double beep which is ok. But this double beep happens again randomly throughout every journey. Above the head unit the display sometimes shows Navi System or other. There is usually a double beep as there is a random change in the display. Almost as if there is a loose contact and it is rebooting. I have checked everything and it appears to be ok. The second and the worst of the issues is the continual background hiss / noise and also a buzz when the screen is pressed. Although it has improved with the isolator and is drowned out when the radio is turned up, it is still present and is very annoying. I think it is not to do with the head unit, but perhaps the car wiring harness from the head unit, to the factory fitted bose amplifier. Although the head unit was meant to work perfectly with the bose amp, I think this is the issue. I cannot take the amp out and bypass the head unit directly to the speakers, as they are low ohm speakers and I think the head unit would eventually damage the speakers. I have been reading that with the factory fitted radio there is a low level output signal, from the headunit wiring harness to the bose amp and a line level output to the mazda 6 with non bose system. I need to understand if I can alter the wiring harness and how to, or if I can add something like 2.2K resistors in line, on the speaker outputs in the head unit wiring harness. Any tips, ideas, help welcome. I hope this rambling makes sense. I have tried a few different roms and they haven't made any difference. I had thought of taking the canbus off and using the swc wires into the harness, but this would limit the usefullness that the canbus gives. I believe it also creates a problem with the reversing camera (which is my next job to tackle).
[MTCD Android Head Units General] Oberbergler:
Do you hear the background noise more, when you step at the gas? If yes, then it is because of a cable that is in contact with the cars body. You have to search the cable which causes this. It can also be the minus antenna cable from your new antenna, a cinch cable or any other plus and minus cable. The problem is very common for Bose sound systems. Many had only to better solder the minus cables of the sound system. Others have seperated the current and cinch cables and it was gone. In German this problem is called "Lima-Pfeifen". Don't know how to say it in English.

Could you give me the link of the Dab app. I am corious about what app your dongle uses. Maybe I can help you with the problems caused by the app.

I upgraded to the most recent version:

KLD_V2.57_1

The firmware I used from Malaysk 6.0.1 MXC89L 20170901 180527 test-keys

And nothing changed.

I'm using CONNECTS2 only to turn ON the Bose amplifier through CAN Bus, because two cables KEY1 and KEY2 doesn't work with my wheel keys.

The key1 cable from this Mazda Plug is directly connected to the radio to key1 cable and nothing more.

I can programm only one function, i.e. volume up, and after programming this function is available on every key in the wheel key, not only in volume up key, but in volume down, next song, previous song too.

I'll buy this SWC interface:

https://axxessinterfaces.com/product/MZCC-01?page=6

Maybe it'll work with my keys through CAN BUS.

What do you think ?

Thanks.

[MTCD Android Head Units General] ikerg:
So it seems that you need the SWC retainer. Or a can bus capable of doing more things...

Do you have reverse camera? If so...how do you get the reverse signal?

I think that bit is better to engage only one box that two different...
