this problem...

Known issue: On devices with 1 GB due to lack of RAM or another videocodec hardware, the built-in video player and other programs that work with video does not work normally.

The pre-installed Video app gives me the "invalid path or files not supported" error, but a third party app like VLC player works like a charm.

Is it possible to activate the google search bar and be able to interact with the HU by saying "ok Google". I'm playing around with Nova Launcher right now but when i click on the google microphone symbol it says " app not installed". Im justing MicroG and with your Rom my HU works super smooth. Is it possible to activate it without losing to much performance? My Goal ist to make handfree calls and use the navigation without touching my HU. Thanks for ur help
[MTCD Software Development] chandlerp:
Everything was working more or less fine on version 2.0 for me but I had an issue with MicroG app settings page and the Play Store automatically starting on boot which was a nuisance.

Now I'm on version 2.1 at the moment and I've been able to resolve that by using the option to not restart apps when booting.

My only issue now is that when I'm using Spotify or Radio Player app (the one on the Play Store not the FM radio app built in) if I switch to navigation Spotify or Radio Player stop playing after a short time. I've made sure nothing else is running and it wasn't an issue in 2.0

Is this something anyone else has noticed? Is it likely something that's been fixed in 2.2? I can upgrade to 2.2 tonight if it's going to fix it.

Feedback on V2.2

Alright, this is my feedback on [MENTION=5092263]Hal9k_[/MENTION] ROM V2.2

I just update the HU (RK3188_1GB ram_1024*600) from V2.1 to V2.2. No visual change on Theme, Launcher and... was seen just a notification of USB or SD card storage was hidden which is good. On V2.1 I found out I need to change the Display mod in Waze app (Navigation) to make it stable while in Auto or 3D mod display it crashed every time but in the 2D the app was stable and smooth. now on V2.2 using MicroG framework even in the 2D display the app crashes and I have to hard boot the HU :( All other apps work fine and in MicroG I have 400 MB free memory with clean multitasking list.

I will reinstall the Waze app later and test it again. Today We had a rainy weather and now its time to enjoy the fresh air even without any Navigation tool:fingers-crossed::laugh:
[MTCD Software Development] Hal9k_:
I wrote that the possibility was added, but I did not promise that I would use it right now. :)

Making a large update package apart from full firmware package is also a big job, which takes time.

You mean the toast in which the numbers are running?

I think you somehow run an auto scan or scan to the next station in the Radio. Try to switch on the radio at this moment. You will see that the red arrow at the top crawls to the right.

[MENTION=9036806]PatrikI30[/MENTION], Thanks for the feedback.

>-The name of the station

Now the name of the radio station is tied to the frequency.

If you stored one frequency on the button, then another, and then again the first (Even on another button), the old name will be prefilled.

I'll think about which option is better.

Our radio stations transmit to RDS not only the name.

In the first variant, we can get, for example, the phone of the advertising department as the name of the station. :)

>-Then, I am not sure about RDS functionality...

So, the second option is better ?

>-Therefore I would like ask all if somebody has extracted radio app from version 2.0

Added unmodified APK from stock to the post.

>-It would be fine somehow be able to open that directory which is already playing (e.g. by pressing folder name).

What is it like ? Swipe from right to left show a playlist. Is not that what you need?

I think that a kernel modification is needed to solve this problem, which is very difficult without the source code.

So I continued the branch 1.x with the same changes.

[MENTION=8718422]drizzor[/MENTION], this is because the Google app is part of Gapps

It was deleted when you switched on microG.

You can install it, but it can negatively affect the performance. https://play.google.com/store/apps/details?id=com.google.android.googlequicksearchbox

[MENTION=331230]chandlerp[/MENTION], What is your navigation program? Is it set by default on the Navi button? Post a link to the app.

Also post a link to your "Radio Player app".

I can try to reproduce this situation.
[MTCD Software Development] Hal9k_:
I remind that installing versions 2.x on an older coreboard with 1GB of RAM is primarily an opportunity for enthusiasts who are ready to deal with possible difficulties on their own.

For other owners of coreboards with 1GB of RAM, which want new features and stability there is a 1.x branch.

Hi. I would like to say thank you for your work and mod you have provided for us. I just tried Hal9k Mod v2.2 and it is working very well but i have got an issue. The problem is that i can not start playing music from the widget. I have to go to music player and come back to home screen to operate via widget. For example radio widget works all the time so it does not matter if it is on or off i can always switch it on from widget. Music player is different and once i stop the music i can not play it again from the widget. I have to open stock music app again and come back to home screen. I guess it is only small bug. I also would like to ask if there is a chance to open music player from any of physical buttons for example that ams button i have on my station(eonon ga8198). I also did notice that installing aps takes little bit long and wifi is little bit not stable as during download it stops downloading for few seconds and than start again but that is not a big problem, i can wait little bit longer. Thank you so much. Here is link for the video to close up the problem https://drive.google.com/file/d/1mJo...w?usp=drivesdk
[MTCD Software Development] itsjakeo:
Would anyone have any advise on how to fix wifi? It'll say wifi disabled and it's trying to turn on then it'll just freeze. I usually have to unplug it 2 or 3 times before it starts working again. As long as it's disabled it's 100% going to freeze on me.

Thanks!!

Hi,

Thought of sharing with you my experience. And perhaps you could tell me what could have causes the problem.

Unfortunately, after having 2.1 release installed on my px3, everything went great! but out of a sudden (after 2 weeks) the unit just shut off itself and went bricked.

I tried to get into recovery mode but without success(hold power button down until light flashes and immediately quick press power button again) Also tried with SD install tool but the SD or USB devices were not detected.

After contact HA(Hot Audio) they thought its the main board that was the problem and so they send me a new main board for replacement.

I still want to have this mod, perhaps with your new 2.2 release. Just before I'm going to do that would be nice to know if there's any issues that I should watch out before installing. By the way, did any of your users using 2.1 version had any problem? I hope it was the hardware that faulty.

Thanks!

Moss

Hi, what do you mean by this change? I hadn't used Google Maps on my device since installing 2.1 and I just noticed today (I havent updated to 2.2 yet) that navigation prompts are muting other things like the radio or a2dp. Will updating to 2.2 fix this, or is this on purpose?

Problem with AC unit on Chevrolet Malibu 2015

Hi,

I have the PX3 I stalled for about 3 months and it's working well.

Most recently my AC unit is acting strange: when I turn it on in normal mode (non recycle) the air flow is very low in max speed. When I change to recycle mode the air flow becomes very powerful, as should.

Also, when in recycle mode I can smell everything outside the car such as a bus although previously in recycle mode I couldn't smell outside smells, as should.

The car shop claims the AC is acting this way because of the non-original PX3. Even though I told them everything was working fine for the past 3 months.

They told me to switch back to the original multimedia system and then everything will work fine as well.

Obviously I don't want to do that and lose all the great functionality I have today.

Any ideas? Suggestions?
[MTCD Software Development] panteryx_26:
If it worked with the unit... There is no reason it would suddenly not work. Also your AC should be independent from your head unit. Mine fried and I drove my car for weeks without being able to use my head unit. The climate is totally independent....and it should be on any car. So try going to a different mechanic.

Rom Install is good, but the recovery does not update

I have tired a lot of things including installing factory ROM, Malyask Rom and installing Hal9K's 2.0 and 2.1 roms multiple times.

For isntalling Hal9k's rom I have tried both doing a dirty install as well as following the instructions of using the SD card for recovery and USB drive for the nupdate.img as described in the 2nd post.

The Rom installs fine, however the recovery does not get updated. What I am noticing is that if the unit boots from the SD card, it boots with the correct recovery, however when I remove the SD card and boot into recovery it boots to an older recovery. It looks like that the recovery does not get updated.

The unit functions fine and there are no problems except until when I try to switch to MicroG. When I switch to MicroG, the unit reboots into the old recovery and never finishes the update / changeover to MicroG.

I had posted about this issue before and I was asked to upload a video of upgrade process. Here is the link to upgrade process that I followed.

Waze issue

Hi, guys.

I'm having an issue that's driving me crazy. I've recently updated a lolipop head unit with Malaysk ROM (1 GB MTCD) to this new Hal9k nougat ROM. Everything works pretty well, but I am loosing my Waze session info almost everytime I step on my car after being parked for a few hours. Although I signin again, it is not showing my favorites, my custom settings and my home and Job addresses. I have to clear data, clear cache, and sign in again in order to recover everything. I am running this ROM with MicroG libraries and the latest Waze version. I ThinkCentre i've donde this process, at least, ten times within the last 3 data.

Thanks for your help.

Is your HU a Lolipop unit? If so, you have to follow the procedure described in the second post.
[MTCD Software Development] demetry14:
Try setting your head units CANBUS correctly in Factory Settings. My head unit came with CANBUS set to N/A and I had an issue with recirculation not working. When I changed the setting in CANBUS to 111 (my car is a Lancer Evo) it made it work again after rebooting the head unit and power cycling the car.

My assumption is that CANBUS is used in relaying that information in my car where I would normally think it would be a simple electrical signal turned on and off. As to why it worked and then didn't... Could be "muscle memory"! But let me know since I had the same issue and this resolved my issue... Would be nice to know if it was an incorrect factory settings that truely resolves it.

[MTCD Software Development] SirCore:
Thank you, how do I change the settings in CANBUS?
[MTCD Software Development] demetry14:
Settings > Factory Settings > Password is either 126 or m123456

Then in Factory Settings click CANBUS at the top and choose you CANBUS from the CANBUS drop-down on that page.

Save, then Exit and reboot when prompted.

Hey there

I finally gave up and decided to reflash the HU to 5.1.1 Hal9k ROM since the V2.2 didn't satisfy me due to lack of memory. I

definitely say

Nougat Android is not suitable for the HUs with 1GB ram! Everything is nice and smooth but in case of videos and specially Waze navigation app which freezes even in MicroG framework. I hope V1.3 of Lolipop is similar to V2.x in case of visuality and will be smoother and more stable for low ram capacity HUs.

Wish the best for [MENTION=5092263]Hal9k_[/MENTION] and you all. God bless ya.:highfive:

Going on a week now. My unit is useless at this point. My wifi and usb go out and freeze my unit every 5 minutes. I have tried everything and at this point I am flashing with every stock rom I can find for my unit with no success. Im periodically talking with hot audio for some help but not getting very far. I am super bummed
[MTCD Software Development] demetry14:
Go into factory settings (password: m123456) and disable WiFi, Save, Exit, Reboot... Does problem persists?

Either way, re-enable WIFI and Disable USB, Save, Exit, Reboot... Does problem persists?

If it persists in both cases, disable WiFi and USB, Save, Exit, Reboot... Does it still persist?

If in the end it is still persists, your problem is something else.

I don't think rom is your problem.
[MTCD Software Development] itsjakeo:
Thank you. I followed these instructions but I didnt have a wifi option to disable but I did see my CANBUS options which were set to none. I selected my car and so far everything is in line.

I have a problem with this head unit database. Some times the open door indication didn’t work I should resset the head unit from the reset button and then works normally. The same. HAppend with the vehicle app only shown dash after the reset work again

Any fix thhks
[MTCD Software Development] itsjakeo:
I'm not for sure but if you have CANBUS, I would definitely go into factory settings and make sure it's assigned to your car. I somewhat had a similar problem and it was just that.

Good luck!
[MTCD Software Development] SirCore:
Thank you very much, the right CANBUS was already selected - 56GM(simple).

I tried other setups but the problem persists.

I'm sure there is something wrong with the software logic:

When air circulation is on, the flap allowing outside air opens instead of closing.

Also, the drop in air pressure in non-circulation mode has something to do with the AC temperature.

If I turn it to minimum (coolest temperature) the air pressure becomes normal.

Is there anything else I can do?
[MTCD Software Development] demetry14:
In factory settings under CANBUS, air conditioner, choose swap not normal.

Drop in air pressure is low a134 refrigerant I think.
[MTCD Software Development] SirCore:
Unfortunately the "swap" option only swaps between the functionality of the two buttons: auto AC and sync. It doesn't affect the problem.

What do you mean by "Drop in air pressure is low a134 refrigerant I think"?
[MTCD Software Development] PatrikI30:
>>>>So, the second option is better ? I think

What you did is very useful functionality and I think a lot of users appreciate it, but I think it is mostly for the users which do no travel long distances. As the name is tied to the frequency. When I store BBC on P1 (under 100MHz) and I moved 200km away, I want to store BBC again on P1 (as the radio is not able to find it automatically) but now under 89.5MHz. System doesn’t offer the name of the station and I have to enter it manually (which is not very safe while driving).

Therefore I would prefer following (while storing):

a) Tie the name of the station to the Program button (not to frequency). E.g. P1 will be always prefilled with "BBC" while storing (of course I can manually modify it).

b) always prefill it with the RDS name , and if I press OK, store RDS name, If I store CANCEL, store what was there before

>>>-Therefore I would like ask all if somebody has extracted radio app from version 2.0

>>>Added unmodified APK from stock to the post.

Could you please let me know how can I install it into my radio? When I try to install it, system says, the file is corrupted.

>>>>-It would be fine somehow be able to open that directory which is already playing (e.g. by pressing folder name).

>>>What is it like ? Swipe from right to left show a playlist. Is not that what you need?

..not exactly. When I swipe it shows me a playlist (nice feature) but there I can list only in current directory, and cannot list in directories (I would like to be able list in directories but starting in actual one). But this very very " nice to have " . I am happy also with today version.

Have a nice evening! Thank you for doing it for us.

Btw: supporting you means a paypal payment? It looks like it is done on official paypal web, I am right? So it should be absolutely safe, is it?

Thank you in advance!
[MTCD Software Development] PatrikI30:
RDS function

>>>>>>> RADIO STATON NAME <<<<<<<

I was thinking a bit more about it. I think that the best functionality which I think will satisfy most users is following:

When storing station to the memory program:

1) Radio always offers RDS name (the name is prefilled, but can be modify)

2) When user press OK, whatever is in the "message box" (message box - added by hal9k) that is stored (RDS name or anything modified by user)

3) When user press CANCEL, original (what was there before) station name is left. So when I first time store on P1 manually entered "THIS IS IT", than THIS IS IT will be kept as P1 station name, during next station storing, when I press CANCEL

4) Do not tie station name to the frequency but to the button (memory program) (as one stations broadcast on different frequencies)

So I think this will cover users which want to have their own name and also those which always prefer RDS name..

>>>>>>> RADIO AF (ALTERNATIVE FREQUENCIES) <<<<<<<

Then regarding the AF functionality. I am not sure if you can even influence it. But let me explain how (I think) it works and how (I think) it should work:

If I understand it properly:

- any radio station broadcasts (in the same country) on several frequencies (Example: BBC broadcast in the Czech Republic on 88.7MHz In Prague (Area1), 97,5MHz in Jihlava(Area2) and 100.1 MHz in Brno (Area3) ). This AF are broadcasted together with “music”. Radio with RDS support can work with it.

- I think that our radio is able to remember also all AF, but only when it is turned on and only when i am lessening to particular station.

Example: I am in Prague (Area1) I am listening BBC on 88.7MHz. I started my trip to Brno. I am behind Prague, between Prague and Jihlava (still lessening radio BBC) when signal becomes poor RADIO automatically tuned up to Area2 MHz (97,5MHz). So when I am listening all the time it works fine, as I guess it all the time has in memory all AF. But now I stopped lessening radio (start listening Music player). Car in-between moved to Area3 (Brno). Now I turn on radio, there is no reception on 97,5MHz, radio automatically does not start search BBC on alternative frequencies (I think because it does not remember all AF). I press P1 (BBC), that program is tied to one particular frequency (88.7MHz). I hear noise. It doesn’t start search all AF ... and this is the problem. I think that it should remember all another AF somewhere in firm memory (even when there is no reception on 88.7MHz, it should start check all other AF tied to particular radio station). ..

Now (as I am now in Area3) when I manually tune up 100.1 MHz BBC radio is there.....

So my opinion is, that the problem is that radio doesn’t remember AF (all alternative frequencies). It can work with it, only when particular station is tuned.

But as I wrote I am not sure if this SW or HW problem and if can be solved by our guru 

This is something I would really appreciate :))

[MTCD Software Development] typos1:
I am sorry but you are wrong - as long as you use microG this Nougat ROM is fast for 1Gb units, the video problem is NOT due to RAM but due to the codec in the Nougat ROM not working with the video hardware on factory Lollipop units and its this that causes problems with Waze, NOT the lack of RAM. This Nougat ROM is good for 1Gb units as long as you use microG, dont use Waze in 3D mode and use a different video player to the built in one.

Have you tried updating the MCU ?

Is it set to "mix" or "switch" ? Sounds like its set to switch to me.

Use a mouse.

Your screen is mirrored as well as upside down.

Read [MENTION=4974080]marchnz[/MENTION]'s "Cross Compatible MCU" thread - there is info in it on how to change the screen config of the MCU.

You may have to experiment a little as I m not sure anyone has experienced both mirroring and upside down before, but it will get you on the right track at least.

Yeap. I had no problem with a third party video player like VLC player which I have mentioned before.
