I have a very strange issue with my PX5 system installed in my BMW E39.

To be able to see and control some of my car functions, i am using the Ibusapp, with a USB module module which talks to canbus of the car.

This app was just updated , and since this update, I have issues with going forward of back when using spotify. As soon as I press Forward , next song comes up, but pauses immediately.

So what I did was uncheck all the option inside this Ibusapp to control my steering buttons, but if I do this, buttons no longer work, except volume.

Next step was to stop Ibusapp at all, but again, only volume buttons work.(but no visualization on screen of volume going up or down)

No idea why . Next I was wonder if I need to re assign my buttons inside Hal9K.

I have the App Wheel keys (or something like that), but inside this app i am not able to do anything. Only have two options: reset and Save, but pressing one of those dont do anything.

I now that inside the Factory setting. there is a second option to assign wheel keys. Already saw some videos about this.

now is my question:

By re-assigning buttons, is this only for the buttons on the main unit, or can i use it to assign also steering buttons?

I've asked this a couple of times in this thread too.. It's my most wanted feature! Is it possible?
[MTCD Software Development] Clandaries:
Try Tablet Messenger (Whatsapp Web)

Or AudioBT

AudioBT is working best with rooted phones.

I use Tablet Messenger. It is working very well on my head unit.

Use someone Backlight auto level app Hal9k 8.0 rom ? Updated today 1.3-->2.0. New version not work fine. Empty day at night time.
[MTCD Software Development] Haebbe:
Hi all together,

first of all I like this HAL9K MOD very much. Its so much better than the stock ROM. Thank you Hal9K for doing this !

I hope it is it ok if I report possible "Bugs" or "improvement suggestions" here?

Because I found some possible issues when I entered my Internet APN manually.

First of all i could not find a option to set an internet APN entry in the list as standard by myself. I could see that the original APN is used as standard by the system but I cannot find the ability to define my self-created APN as standard, which would be very helpful, because sometimes the selection in this APN was set back to standard where my internet connection didn't work anymore.

Can this be maybe improved for the future if possible?

Also if I create a new APN manually and I enter the data like "Name", "login", "password", "server" etc. the pop-up field, which comes up, always has a white background and the letters are also in white color, so the user cannot see which letters he really entered and can only see after confirming the entry if its written correctly or not.

Can this be maybe also fixed for some future release versions ?

Thank you very much in advance and best regards

[MTCD Software Development] kowski10:
Hey I have the same problem. It seems to be a bug inside the IBus-App due to the new px6 device support. To fix it I've reinstalled the App Version 2.1.2.1 and it now works again without problems. I've also reported the bug so it will maybe fix with the next update.
[MTCD Software Development] papa4:
Congrats Hal9k on a really great job you did with this ROM! I am running it on an AndroidAutoShop HU for Citroen C4, PX5.

I have a problem that I read a few more users have encountered: when I try to select "Key Study" or "Other" I get "com.hct.factory" has stopped error.

I have a hunch that this error might have something to do with the Steering wheel keys. When I first installed the HU I mapped 4 key from the steering wheel and later I flashed Hal9k (with the wipe of data). However, the key mapping Steering wheel keys survived. Now the very first time I ran the Hal9k the keys worked as mapped on the original ROM and the mapping was in the Steering wheel keys section. I removed the mapping from there, but the keys continued functioning as mapped. Also, when I go into the MOD settings to remap the key the only keys that show up as pressed are the keys that have been mapped in the original ROM. But even stranger, the keys that have not been mapped neither in the original ROM nor in the Hal9k work (e.g. Menu button on the steering wheel) but do not show up in the MOD settings! I can provide additional details and testing if needed.

I've seen some of you fix the problem with the dmcu.cfg files from an identical MCU HU. My MCU is MTCE_MX2_V3.08_1 and CANBUS decoder Simple, so if anyone can share their dmcu.cfg file it would be great (you obtain it by clicking "backup" in Factory setting menu).

EDIT:

I've found the fix from hal9k from a month ago, so I'll just copy it here:

Universal solution for problem: settings app crash by click on "factory settings - OTHER" and "Factory settings - KEYS" )

1. Go to the “Factory Settings” and export the configuration to dmcu.cfg file on the flash drive.

2. Open the dmcu.cfg file in the HEX editor and change byte 02 to 01 at offset 0x55

3. Go into recovery and apply the config using the "Apply update mcu" item

Hello,

I can not use viper because any driver is missing the download but unfortunately not synonymous. Is there a solution?

What bothers me too is that constantly small pop-ups are displayed where then, for example, the channels etc. of PCR radio show, I can turn off or reduce that it is not so often this popup?

How is the stand at Android 9 Hal9k Mod?
[MTCD Software Development] ikerg:
Have you checked that your bluetooth type is well configured in factory settings it seems that your settings have been lost during mcu upgrade (it is always recommended to export settings prior to upgrade)

On factory settings depending on your hardware settings several internal apps are hidden or visible...

Hi, is there a way to show cover info when playing Bluetooth content?
[MTCD Software Development] Hal9k_:
If you have a PX5 MTCx device, I think so. Look in my signature.

Factory settings are stored in the MCU and remain unchanged when installing another Android firmware.

Poweramp itself is the root of the problem. I never liked it. :D

In this case, it looks like a damaged hardware.

There is a better way.

This is a rather old version. Better to upgrade.

ModInstallerPro is designed for such a case. Look in my signature.

Now I do not recommend the way with boot cards.

Yes, I remember that.

I'm very impressed by all the work you've done ! Bravo !

Do you think it would be possible to developp an application, or mod, to work with second displays in car ? In a lot of car there is a second display that display song track for example. (Renault Clio, , VW...)

All of these can be done using CANBUS, and address to write on can be found online. Exemple, or Exemple

VW can forward navigations direction to dashboard but maybe we could even display notification on it ? It would be very nice !

Guys this is going haotic here. Can you please do a new thread for anything related to android 9?

I see people installing 9 and ask for modinstaller, other ask why in 9 their launcher is not like the OP images and many more questions because the thread is mixed.
[MTCD Software Development] Hal9k_:
There will be an update 3.1.2 as soon as I deal with one thing.

If you mean the stock HCT firmware based on Android 8, then you just need to install update.zip

You can find this launcher only in HCT firmaware. For example, hct4_PX5_9.0_ota(20190505)

I have not tried. Try it.

I use the button of turning off the backlight in this case

Not having such a car is difficult to do.

Thank you for the great USB support in this ROM, after switching to Hal9k I got rid of all the USB permission popups and have fully working CarPlay, DAB+ and Torque with my OBDLink SX USB cable through a USB hub.

I've flashed it today on the a-sure head unit (MTCE / Android 8) with your flash tool. The update went through and everything works fine so far except one thing.

Whenever I'm trying to set the default navigation app in the settings, the setting panel just crashes :(

The latest OTA have been applied too.
[MTCD Software Development] TheBambi:
Would not expect there is an easy way to write messages to canbus. As far as I understand in many cases the units have a external canbus decoder. This decoder is connected to the cars canbus wires. The canbus decoder box translates known canbus messages. For example ignition on, reverse gear, key press. For some brands like VW and Audi this decoders also will send probably some sort over serial messages to the radio and are able to receive serial messages which are translated to corresponding can bus messages. For example in my Audi in the first line of the cars display the station name was visible.

The hard part is for every car brand and model you would need to reverse engineer the canbus messages used. So even if the source code for such canbus decoders would be available you would no be able to use it for all cars.

Such a decoder could probably be coded using an arduino or something like this. Not sure of the existing TX/RX lines from the radio could be used to read/write all messages you would like to display or if there might be restrictions inside mcu.

Might be a good idea if you would open a new thread (but first search xda, maybe someone else asked already) as this does no belong to Hal9k ROM.
[MTCD Software Development] UnReal':
Thanks you for all theses infos !! I can imagine that reverse engineering canbus messages would take a lot of times but we can find on the internet some precious infos for many brands, like I sent ! (And for exemple, VW, Audi, Seat, and Skoda use the same messages...)

I know that some Head Units can do more than other with Canbus, so I think that as long as your CANBUS is connected you can access it ? (Here you can find an Head Unit compatible with navigation, TPMS, Bluetooth and Radion on second display for VAG cars (just scroll down pics)

Maybe we could imagine something like an API in the ROM to specify what to write on CANBUS when something happen? ( Change of track, change station, navigation or even notifications ?) I think that the community could help to find CANBUS message to display on speedometer/second display ?

Hello, new member but longtime lurker. I would like to thank [MENTION=5092263]Hal9k_[/MENTION] for the MTCDialer update, I was able to successfully install on my Dasaita PX5 MTCD.

I think I know the answer to my question but want to ask anyway, does anyone know if I install this ROM would I have the ability to remap my steering wheel controls. The seller says it is determined by CANBUS so I am guessing answer is no. I have a 2018 Toyota Auris and the "mode" button the wheel scrolls through radio, bluetooth, video, DVR I think, things like that, stuff that I don't use. It would be great if I could map it to scroll through apps like Waze and Spotify. Any information would be greatly appreciated.

Thanks in advance.

Hi there. Got a problem with the Gala-mode in mod settings. I've activated it before I updated to the latest version of the Rom and can't deactivate it now. I've unchecked the GALA activation box but the volume still changes when I reach the before predefined speed. Also deleting or changing the speed values won't change anything.

So how can I get this option deactivated again? Is there a way to reset this options manually or can I do a specified data wipe without losing all my other settings?

Thanks in advance.

BTW: since the update the screen saver does not work either with tapping on the shutdown button.

Again, thanks.

Two questions for those with the best knowledge of the hardware of these Android head units. IS A HEXA CORE(6) PX6 (Newest) FASTER THAN AN OCTA CORE(8) PX5 (Older)? The Hexa core has a RK3399 with I think 1.8Ghz dual core, and 1.5Ghz quad core. Do you think this updated newer chip is faster with less cores, than the older PX5 Octa core???

Second, which manufacturer is better and more reliable, Dasaita or Seicane?

Hal's rom is NOT more stable. Sorry, but just to be honest, I had a few problems with Malaysk rom, and switched to Hal's rom for this very sentiment.

It's no more under development but it works.
[MTCD Software Development] Silver_:
Hello [MENTION=5092263]Hal9k_[/MENTION] Thanks for your last update. The truth that this ROM is going quite well. The only small drawback, although I consider it as a minimum fault, is that when an application uses the voice systematizer (eg the "Google voice") if it is started before the Radio, it takes control over the voice channel and no problems this time; but if the Radio initializes before , does not get to take control over this and causes the sound of Google Voice does not muffle the Sounds of the Radio (only mixed).

Another small suggestion is if it could be modify the Register where the "battery voltage" is taken by another one more accurate(of CANBUS, as programs like TORQUE ) , because in my case the battery voltage is not very consistent with reality.

Thank you for listening to us friend and especially thank you for your work.
