really thanks thanks, now I have to figure out how to load it on the device because I currently have a blue screen.

do you have any idea how to do it?
[Android Head-Units] braisel:
With rooting the device, are there any new options or tools that could grab the signal from steering wheel keys and connect them to third party apps as well, so that its not just the house music app that is able to react to the steering wheel keys?

Im not that deep into that stuff, just the basics, but if someone could find a way how to modify that it also works with third party music apps, that would be awesome!
[Android Head-Units] braisel:
For those of you who have also problems with the forward/backwards steering wheel keys in combination with third party music players, here might be a solution for you. Its an app from a russian forum:

https://4pda.ru/forum/index.php?showtopic=899753

I tried it and it works for my device, forward backwards and pause/play keys are all working now. the only problem is that probably due to android 9 the service is getting closed after a while, so you have to open the program again in order to get it work. just a minor thing, but maybe theres a solution for that as well, going to text the developer to see if he can fix it.

My device bought from Bosion store at Ali version 1.1.4.3.1.20191028-11-KC6-41.

Apart from overheating the major problem I have is Android part freezing at boot (every few starts of headunit). It is stuck at Android logo (I guess maybe it didn't shut down properly in previous session). At first I thought that it might be impacted by USB stick. I copied all my music into internal memory but problem still repeats. Non android part of the headunit is fine and working (reverse camera, etc). After full shutdown (I preset it to 10min) it restarts fine. So it is really annoying. Can you help? Any ideas? No root, stock apps+ google services. Do you have that problem at all?

same unit - also problems

Hi all,

I have the same unit, Eunavi branded.

I have issues with power (drains the battery even if switched off) and no rapid start.

One of the USB doesn't work and the radio won't hold the presets.

Any ideas ?

My software is

OS: KC1E0105-P01-1.1.4.3.1 - BLINK161 - 20191009 - N3

MCU: STM32-20190918-11-KC6-37

Suppose I should start with an update ?

Got it through Ali-E, I am in contact with Eunavi but not expecting much help.
[Android Head-Units] pinotuning:
you badly mounted your radio!

yellow cable + 12V direct battery power supply

red cable + 12V power supply from ignition key

black cable - Ground
[Android Head-Units] sekitori:
Pinotuning, thank you for replying.

That is what I thought too, but the thing is that the connections on the sticker on the unit and in the manual (well, leaflet....) are different.

Which one is supposed to go where (pinnummers rather than colors) or maybe you can post a picture as the numbering of that connector on the back is also not very clear.

I checked the connections in the car with a multimeter, so I know which is which on that end....

Still left with the other issues but I'll try and sort this one out first.
[Android Head-Units] pinotuning:
I believe the problem is wrong connection! I on my car I had to change the position of the cables on the ISO connector! some cars have different connections! which model is your car radio?

if you lose radio stations the problem is the connection of the iso cables! post iso connector photo of your radio
[Android Head-Units] pinotuning:
my head unit uses the first diagram

See first photo

if your radio is the same as mine diagram says:

Pin 1: Ground (black)

Pin 2: acc key (red)

Pin 9: + 12V BATT (Yellow)
[Android Head-Units] krefo:
Hi.

Does anyone know how to change the color theme? Black font on a dark background of notification bar is illegible.
[Android Head-Units] sekitori:
Power drain

Look like it's the same, I also have a sticker on the unit with pinout of the connector.

On closer inspection, my ISO-cable between radio and carconnector has the wires crossed, like you suggested.

My car is Dacia, which is Renault basically.

Anyway, hooked it back up yesterday after I switched the pinout of the ISO so I'll know for sure in a few days ;)

Can't seem to be able to upload a picture of the sticker....
[Android Head-Units] pinotuning:
yes of course Renault / Dacia are the same! surely you solved it:good:

Thanks

edit : Attention do not update with this firmware because in equalizer you will see everything empty ! no flat, rock etc .....

my radio has advanced equalizer (dsp)
[Android Head-Units] mrVuHoa:
with me, there are no sound after upgrade the firmware, maybe this firmware for DSP one.
[Android Head-Units] pinotuning:
my old firmware is : KC1E0110-P01-1.1.4.3.1_20200323_160300

new firmware is : KC1E0110-P01-1.1.4.3.1_20200411_110825

exactly, this firmware is for dsp radio but

I believe the Chinese made some mistakes

because with new firmware my equalizer is now empty
[Android Head-Units] mrVuHoa:
Do you have sound after upgrade? My head unit no sound, now it's really only for Maps :highfive:
[Android Head-Units] pinotuning:
yes sound ok on my unit but i see the buttons

empty equalizer!

I downgraded to the old firmware

we need custom firmware for models with and without dsp sound

No, I don't know what the exact improvements are. Eunavi said there are several problems fixed, but I haven't tried it yet.

Sorry to hear that there is a problem with the equalizer. I'll try the firmware tomorrow and also test the equalizer.

Very, very nice! :)

Do you have a rough timeline for an actual ROM?

Hi, I saw that you had the same issue no sound after upgrade DSP firmware in 4pda.ru. Have you resolve it? How?

I understand that there are 2 hardware with stm32! with dsp and without dsp! mine for example has dsp and bluetooth 5.0 which supports internet bluetooth and dsp AKM7738 + TDA 7803 other stm32 models have different audio chips! maybe even radio chip is different but I'm not sure about that !

maybe the audio problem is this after firmware updates?
[Android Head-Units] Hekg:
Did you fx it? I have the same radio and I can share the mcu and firmware if you still need it.

No luck, Still no sound. It seems that the firmware not completely replace by new one.
[Android Head-Units] pinotuning:
Your head unit has DSP ?
[Android Head-Units] mrVuHoa:
No, my head unit don't have DSP, but I flashed the fw with DSP and now no more sound.

No, i don't have the backup. Now, I am trying to download all the firmware that I can find and try with luck :)
[Android Head-Units] pinotuning:
you have to be careful when updating the firmware! I tried because it was the same as mine but it only changed the data! so I deduced that it was suitable for my unit! I think it is a firmware for radio with dsp but probably the Chinese have made some mistakes! on my unit also works audio .... there was only the problem of the equalizer

[Android Head-Units] Michalec:
Hi guys,

I've connected today my new Eunavi HU with STM32 MCU and I was shocked... My old HU was PX30 MTCE Android 8.1 and there was a lot of settings available. On this new Eunavi HU I cannot even change touch buttons color (My original Skoda buttons are green, HU is red - it looks awful). After setting 1h AC-OFF setting I've also noticed that buttons are turned on after removing key from ignition. It's a big dissapointment - I wanted to flash a MTCE custom ROM and... here is STM32 MCU...

Waiting for some good news (I hope it will be better after some updates)
[Android Head-Units] pinotuning:
have you installed the radio correctly? however on Eunavi head unit you can change the color of the buttons
[Android Head-Units] Michalec:
Yes, I've installed everything correctly. When set "no delay" on AC-OFF option HU is shutting down correctly.

Where can I found element color settings? I've checked every possible setting...
[Android Head-Units] pinotuning:
on my head unit there is an application to set button lights color! I believe it is also on your radio
[Android Head-Units] Michalec:
I've contacted the seller. They are lying in description... I've thought that "color button panel" with color pallette image means that I can change the buttons color - seller said that in this unit it's not possible and it will always be red... It looks awful when everything is green and HU is red...
[Android Head-Units] pinotuning:
which model did you buy? universal or for Skoda? mine is universal 7 " and I can change the color of the buttons
[Android Head-Units] mrVuHoa:
Yes, I tried to ask them and they still keep silent. I think that I can not expect the support from them.

Now i found some tutorial from 4dpa.ru and try to recover the fw.
[Android Head-Units] pinotuning:
the support of the Chinese is really poor! I hope you can fix your head unit! good luck:good:

Hello! Someone have firmware in IMG for STM32 1024x600?
[Android Head-Units] Michalec:
Mine is for VW Passat and also Skoda, because both of them have the same size and curve of HU.
[Android Head-Units] Michalec:
Unit I've bought for $270 is a piece of ****. Bought PX6 with DSP because I wanted to flash custom ROM with root and make a great configuration, but received ****ty MCU and the worst software I've ever seen... After turning AC OFF delay to any option, after removing key from ignition HU still plays music and key lights are on. Cannot change display size (factory settings option does nothing), cannot skip tracks using my steering wheel keys (there was no Key1/Key2 wiring) and everything is getting me nervous. I'm thinking of going back to my 2GB HU with PX30. Worked slowly, crashed sometimes but was a lot better than this piece of garbage...
[Android Head-Units] pinotuning:
sorry but how does your radio play music if you remove the key? I think you installed the radio badly! Red wire ignition key, Yellow wire + 12v battery and black is ground, check the iso cable well maybe there is an error there! it's strange that you don't have key1 and key2 cables! I have found both cables!

this your radio?

https://m.it.aliexpress.com/item/32...VD7h3Ch2QwguBEAQYAiABEgLrsPD_BwE&gclsrc=aw.ds
[Android Head-Units] Michalec:
No. This is radio I bought:

https://a.aliexpress.com/_BUNtxw

When shutdown delay if off - everything works. But when I turn delay for any option it should go to sleep after removing key. My old HU was in hibernate mode for 1h. When I enter key again and turn ignition on radio should turn on immediately, without hard boot. Everything is connected the same - checked wiring and everything is okay there.

Also noticed today that I can't connect by OBD adapter - it says connecting and nothing happens after dialog disappears. And the most annoying thing - I cannot connect more BT devices. If my phone is connected, then I can't connect OBD adapter...
[Android Head-Units] burjtech:
Upload pics of your iso cable and wiring you have done? It's simply not possible for stereo to work when ignition is off? Most likely wiring has done incorrectly, i look forward to seeing the pics. Thanks
[Android Head-Units] Michalec:
It's connected using canbus, how it's possible that with one headunit it works and with another there is that weird problem with delay option? Also tested with another headunit on PX5 MTCE - no problems. Connection is the same. It's not connection problem - it's software problem. Headunit is not going into sleep/hibernate mode but some weird "screenoff only" mode.

Also I've laughed when saw that only one BT device could be connected [emoji85][emoji1787]

Wtf? Bluetooth allows multiple devices, that's written in standard...

Edit:

After some reading on 4pda found out that this is a software problem - about that delay. I have connected everything as it should be connected. So... We need to wait for fix, if ever [emoji854]

I asked my seller to send me the latest android 10 for my bosion PX6 and he said:
[Android Head-Units] braisel:
Thanks for the tip. Does that still work with Android 9?

I'm in contact with the developer, he has sent me a new beta, which wont get closed automatically anymore. There's just one bug left, which forces the navi to reboot once youre in ignition mode, running the navi and havent started the motor so far. Once you start the motor navi reboots, which is a bit annoying. Apart from that its finally possible to use the forward/backward keys on steering wheel control with third party music players.

Maybe someone can create an overview post, its getting confusing with all those different device number updates.
[Android Head-Units] Michalec:
It works on mine HU with Android 9. But only as "long click". Single click does nothing. When long click I can change track (better that than nothing).

I reduced the contrast to zero and unintentionally hit the back button. This caused me to be unable to see anything on the screen.

Now I need to go back to that screen and hit the Reset SeekBar Values button. How do I do this if I don't see anything?

Now I just see a black screen, I can't see anything. Do I need to reset this setting, is there any way? I already unplugged the power and turned it on again but continued with the black screen. I can only normally see the boot image. I can even listen to music if I know where the play button is. I am using AGAMMA LAUNCHER.

I recorded a video so you can see how it is now:

HELP ME PLEASE!:crying:

Plan A:

Can you help me by recording a detailed video of your HU showing how I get to this "Display Color Adjust Settings" screen? I'll try to reach this screen without seeing anything, just following where everything is in your video!

Plan B:

How do I safely reset settings? (Hard reset would work? Like if I press reset button and clean data and cache, would work?)

Plan C:

How do I reinstall the firmware if I don't see anything on the screen?

Hi,

something similiar happened for me when I was clicking on relearn touch points on screen in hidden menu. That lead me to a non reacting display, so I couldnt press anything anymore. I just solved that problem by pushing something in the reset knob for a short time. Navi reboots and in my case the touchscreen was working again, like before. All data and other settings kept remain on my device.

Hi!

I bought an Eunavi PX6 STM32 HU ~a week ago, of course a lot of things are not working. Tried to speak with the Customer support which is a joke.

However i was in the 15days to open a dispute with aliexpress. Created 3-4 videos with my problems, a loong description of what is not working attached as text. I opted for a 50% refund and to my surprise they went with it.

Just sharing this as if someone else is in the same situation it might be helpful to try asking for a refund.

In the meantime I'm really looking forward to Malaysk firmware :)
[Android Head-Units] rudix78:
I did the same with Boison stm32. I opted for full refund and return. They offered me $100 refund out of $170 I originally paid. But my headunit fails to load every few restarts. It is usually stucked at android logo but it happens also at car logo. I'm als looking forward for Malaysk. I used his software before and it was great.
[Android Head-Units] MarkOrkenyi:
Yeah, i went with the safe option of not asking for a full refund, cause i was sure it wouldn't go with them... But there's no way i'm going to buy anything on ali again.. :)

Luckily for me my HU kind-of-works now, just some features, like the CAN adapter and button lights not working properly, EQ text and notification text are black and some of the DSP features are not working at all.

For this ~$140 i can live with it, but hoping Malaysk finishes it soon and then i can have a better HU :)

Hi, could you please tell what did you send to AliExpress refund ticket? There is a lot of problems with this HU and I think I will try to get my refund too.
[Android Head-Units] MarkOrkenyi:
Hi, Basically i did the following after customer support just stopped answering:

Listed the my problems with details:

-CAN adapter makes the device unstable, steering wheel controls intermittently working, can't set buttons - descriptions says otherwise.

-Headlight switch not changing the Button LEDs, but if headlight is turned on, i can't toggle the button LEDs.

-Only the equalizer works and the centering, other DSP features doesn't make any changes in sound.

-After a firmware update which was provided by the seller, i got black text on black background(EQ, notifications).

-I got the wrong RCA cables - not for the DSP version.

I made short videos/pictures about each of these problems, attached as "evidence" and wrote a 3000 char description about this which was attached as picture as there is a 500char limit ( :) ), added solutions(50% refund, new device, order cancel) and also mentioned with screenshot attached that seller stopped replying.

No action from the seller, and after 3 days Aliexpress just closed it with the 50% refund.

Maybe i could have asked for more, but my HU luckily works, and for 140USD it's more or less good-enough :)
