Wow ... Why are they restricted like that? So the custom ROMs don't lift that restriction? It can't be a hardware limitation given that I've never heard of such a thing in nearly 20 years of using Bluetooth devices. Even using the cheapest of Bluetooth adapters!

You should look at this unit as an accessory that you connect to your phone. It is designed to act like a Bluetooth Headphones device that you connect to your phone. Now, can you connect a Bluetooth Keyboard to your Bluetooth Headphones? The example is a little bit exaggerated, but you got the point.

With Atoto you can connect everything.

My OBD Bluetooth adapter worked in v3 and v4 till last update to v4.2. It does pair with headunit but does not communicate with car's ECU. After a while Torque shows that adapter has error count and it is shown in red colour.

This same adapter connects to ECU and is working with my mobile phone without any problem.

How do I revert to v4.1 ?

With the installation of rom 4.0 in a HA2 DASAITA max6 I noticed that the accuracy of the gps from 1-2 meters dropped to 10-15 meters. This makes the gps useless for navigation. I see the same in the pictures in the third post that you made the GPS shows 11 meters accuracy. Why is this happening? I tried to go back to the rom I had before but the problem with the gps remains. I have changed three antennas so far but nothing.

[MTCD Software Development] dieusev:
After updating to 4.2, gps accuracy for Coyote is back to normal. However another issue has appeared.

After stating Coyote, the sound of music (Spotify) is at the correct level. As soon as Coyote says anything, it lowers the sound of Spotify, which is normal. But when Coyote is done saying it's message, Spotify's sound doesn't go back up as it is supposed to.

I've noticed this issue only with Coyote app, not Camsam or Waze or Radardroid.

I'm currently running 4.1.0 on my Xtrons PX6, Friday when I was connected to the internet I tried to upgrade to the latest version. This however failed, I received the message that there is no newer version available than the current version. Any ideas?
[MTCD Software Development] MarcoZ76:
Hi to all!

i have a strange behaviour with 4.2 upgrade. The bluetooth of my Dasaita PX6 is not working good as before, sometimes my iphone is paired immediately once i switch on the car others it don't.... Moreover the Zlink is not working every time and when it working the iphone is disconnected from BT (maybe is espected to work as it). Could it caused because i use a modem USB stick ? (it work good as ethernet connection). Can hotspot switch off or does it remain switched on to allow Zlink to work? Sorry for my bad english. Thanks
[MTCD Software Development] Stefan McSleaze:
To get Internet access there are several ways to go, via hotspot from the phone or wifi 4g sticks...but some rare 3g sticks are running too! They only use the USB to connect as a modem and dont use wifi.

I found an very old vodafone 3g stick, formerly used to get mobile web for my notebook, years ago.

I took a partner simcard (O2 net) and put it into that stick, activated roaming on the HU (stick is D net only) and now have 3g!!

Its quiet good to join webradio or navigate with Gmaps.

I'm on 4.2 with a 64bit octa PX5

Read first post

You need to flash mcu through android (put dmcu.img on sdcard, wait for popup "update") lastest are : LM 3.47M >> here<< or LM 3.49 >> here <<

Any MCU are compatible A8/A9/A10, just respect your "letters" LM

Hello everybody,

Even if I have read quite a few pages from the beginning of this great thread, I still have not fully understood how to upgrade from Android 8 to Android 9.

My HU has the following details:

px5(1024x600)

Android version 8.0.0

Hal 9k mod v.3.1

MTCE_LM_v.3.07_1

I am a bit confused on how to upgrade to the Android recovery 9, how to update my MCU version, etc.

Could you please provide the detailed steps on how to upgrade to the latest version? Of course, I do not mind donating to Hal9k website to get the OTA updates but I do not know how to proceed from there...

Thanks a lot and I really look forward to your great help!!

Dear hal9k,

I created my custom home screen, added icons and widget, and then moved it to the front, but each time I restart my car the screen goes all the way back - the way it was before I moved it to the front. Could you please fix this bug? Thank you
[MTCD Software Development] CepoSK:
just put the .img file in root and then it's somewhere in the car settings i think, not sure from top of my head (sometimes it will automatically detect it and a popup will appear, but that worked for me only once i think...). You will know when you see it (it's not the update in mod settings)

Hello everyone ! Could someone explain to me how to change the theme of the homepage of the hal9k rom version 4.2.0 for px5? (which is perfect, thanks to hal9k for his work) Thanks in advance ?
[MTCD Software Development] KhangTran476:
The Default Launcher had a few bugs. Never move tabs. Only the icon can be moved.
[MTCD Software Development] Ati_gangster:
There's a bug.

You have to move all icons from the first to another page.

After that the first page will disappear.

Now the second page will be your first page.

Now move all icons you need to the old second/ new first page.

I've made a video about that.

Is It possible to delete this bug?
[MTCD Software Development] warcry83:
Hello ! Thank you for your reply. How to apply this theme for example?
[MTCD Software Development] woAforever:
I "fixed" this (not really) by moving all unwanted stuff from first screen to the other screens, and the desired things to the first screen. Not exactly a very user friendly solution. I'm glad though that recognized this as an actual bug, so now I know that hal9k can fix this.

But I don't really know because I was reading the last 30 pages, and for the entire 30 pages the author of the distro replied to his users only 1 single time which is not very reassuring at all. I wanted to buy, and also donate to the author (hal9k), but now I think I'll rather not do that just yet. I would buy it, if I saw them actually talking to people, and showing involvement, but I don't really see it.
[MTCD Software Development] Ati_gangster:
Its not a bug, its feature ?

To restore standard settings you have to delete app data.

Hi everyone, I've searched everywhere but I haven't found any posts about it.

I would like to create a link on the Android 9 home of the microphone icon inside the Bluetooth app that communicates directly with the phone's google assistant, because to make a call with voice commands it is much more reactive than the google assistant (+ mtcdealer) installed on the car stereo itself. In the linked image the icon is the one highlighted in light blue.

I could not find the command invoked by the icon. It would be fantastic to create a command with Tasker that can be launched with the controls on the steering wheel, but creating the connection would already be remarkable….https://drive.google.com/file/d/1hLwlqekgwfFkStQyi4xGsAWDnBOsjndx/view?usp=sharing

More, In the factory menu you can find a way to set the minimum quality searching signal. Try to increse the db value there.

More, try to check the connection behind the HU; sometimes it's not so stable.

Hello folks.

I need some assistance with updating to V4.0 of Hal's rom. I am currently running V.3 (android 8) on a PX5 MX2 device, without any issues. I am aware of the BT module restrictions and everything, but the process of updating is not clear to me.

My recovery version is also on android version 8 and I am worried about that.

Is it true that a dirty flash of V4.0 over V.3 will brick the device?

Is ModInstaller absolutely necessary (for initial installation-not OTA updates), or is there a workaround this?

Do I need to update recovery first, and then use a "stock" android 9 firmware, before updating to Hal's V4.0?

So far I have only updated mcu to latest available for my MX2 system, but I am skeptical in moving forwards, due to the above.

Any input will be greatly appreciated.

Problem with status bar icons color

Hello guys,

First of all thank you [MENTION=5092263]Hal9k_[/MENTION] for this mod. It's working great and it's very responsive, which was my main goal here.

I'm reaching out to you because I have a problem with how the status bar behaves. It is always in the "white" mode, which means that when I'm opening Google Maps, the icons stay white and are almost completely invisible on the map background. I had other firmwares before and this issue never occurred.

What's weird is that the status bar works as expected when the engine is off. My suspicion is that the problem might be connected to the way screen brightness is implemented with the overlay, because I can observe the screen changing it's brightness significantly upon engine startup, although it's just a suspicion.

Would you be kind enough to help me with this? I feel like it's a simple issue as it actually works correctly when the engine is off.

EDIT: for all looking for a solution: in the mod settings disable Hardware settings -> Additional screen dimming in night mode.

[MENTION=5092263]Hal9k_[/MENTION] seems like a bug.

AF never worked on chinese HU like it works on brand radios (and not on all...) even if they have sometimes a better reception. You should check if you have the OEM aerial amplifier (most have it) is enabled and connections overall: water tends to oxide contact over years. If it doesn't satisfy your requirements consider to add a DAB dongle

Why not install the Google assistant app? You can than link it with any button on your wheel. It is much better than mtc dialer and I never experienced big delays. My phone is always connected to HU as I step in car - made a macro with macrodroid (if detect bt of car than swith off wifi and open hopspot - if no bt of car swith off hotspot and turn on wifi)

[MTCD Software Development] GurbNL:
I seem to have this too... For me, the update to 4.1 already ended in recovery, but after a reboot it seemed fine. Then the update to 4.2 took ages with the colored ring. Then it reboots, shows the colored ring again but this time with the bar filling faster. Midway through though, it stops, reboots and ends up in recovery. I wiped cache and rebooted, but I got stuck at the Hal9k boot screen.

Next, I did a full wipe/factory reset from recovery (the erasing screen took ages again), installed 4.0 and went through all updates. Again, update to 4.1 ended in recovery, again, update to 4.2 ended with Hal9k screen. :(

Edit:

OK, I finally made it to 4.2! It may have had something to do with the SD cards. Here's what I did now:

- remove SD cards from slots

- from the stuck boot screen, enter recovery

- wipe cache, wipe data

- Install 4.0 from USB drive

- wipe cache, wipe data

- reboot

- install OTA packages, without installing anything else and without setting up accounts

- all OTA's now installed correctly!

- activate various accounts, install apps, set up device, insert SD cards again (in no particular order)

- happy camper again! ?

Problem with Radio app startup after sleep.

I have problems with non-standard radio applications. When I turn the vehicle off and turn it back on the radio turns off, it doesn't appear again. I do not understand why it is because I have checked in MOD Settings that "the apps that were started before sleeping are executed".

With modinstaller you can install any rom (custom and originals), the installer installs the right BL for your rom. Of course the rom you upload must be compatible with your HU, that means that you can't upload a rom made only for px30 to a px5

Reverse camera image

Thanks for a great mod! :)

I have installed a rearview camera. When connecting it to AV-in it shows no guidelines but they are there when connected to "Reverse camera".

So it seems the gridlines are added in the system and not in the camera.

They are not the guidelines from within car-settings in android that you can adjust. When I enable them they get superimposed on other ones.

Is it possible to remove the guidelines on the reverse image (so that I can use the ones in the system that are adjustable)?
