What you searching is the camera

Settings-->hidden menu--> modules -> camera

You then need to make a restart of the device to get the changes you made. Get a restart app from Google play for that.
[Android Head-Units] rigattoni:
No additional app needed.

Just push the RST button in the front with a tooth pick. That leads to a full reboot.
[Android Head-Units] tlqkf18:
Unfortunately, I couldn't find a rear camera related menu in the hidden menu.

There was a front camera or an M camera, but...

Eventually I gave up and went back to the 20200721 rom, but now the sound and handle buttons do not work. I've been stuck with this for days, but it doesn't seem to work, so I'm going crazy.

My android head-unit doesn't allow to control subwoofer gain level expect for the crossover.

On my old android headunit (no DSP) i could also set the subwoofer level. Is there any app i can use that allows this?

hardware:

Joyx PX6 4/64 (no DSP)

hi.

I installed the DSP version you linked, but there is no sound. Is the version with DSP correct?

The Dropbox link address is the same for both the With DSP and No DSP versions you linked.
[Android Head-Units] berrie60:
I have the same problem. Did youfind a solution?
[Android Head-Units] berrie60:
whenever I start the car, the EQ will be back to default.

I need to press the EQ button/app and then i custom EQ will be back.

I think likely is some setting i miss.??

Hello guys, can anyone with a working back camera post the exported config file so i can patch mine ? Everything works except reverse camera since i've done a factory reset/flashed another software. I have no options for back camera except "camera: normal/mirrored" in factory settings. I've opened my own config file and i think this is the option i have to modify, but i don't know what to modify here.

Thanks
[Android Head-Units] Lolo13010:
Hi.look this. Maybe reinstall Factory apk ?
[Android Head-Units] r473r:

Hello! I've just got this unit from Eunavi for my BMW E39. My data is following:

Android Version: 10

Hardware Information: RK3399 - ROM 64GB - LPDDR4 4GB - 1024X600

CPU: 8 Core (Quad Cortex - A72@1.8G Quad Cortex - A53@1.5G)

Kernel Version: Linux 4.4.167+ - Thu Aug 6 16:04:11 CST 2020

OS Version: KC1E0130-P01-11.1.4.8.1 - BLINK161 - 20200806 - N3

MCU: STM32 - 20200721 - 11 - KC6 - 40

The device works pretty good, except the following issues... There is almost no bass on whichever type of music it plays. Bluetooth, radio, youtube... Everything is flat at sounds terrible. DSP settings (EQ) helps a bit, but still very poor flat sound, much worse then my old android non-dsp unit... Then I discovered the settings screen for DELAY and I tried setting rear speaker values to more then 200 and BAM... Great and very clear bass is there... But whenever device resets, it loses the settings :( Actually it visually shows as its still set to previously selected value, but the effect of the value is not applies, up until I try to re-set the value again (playing around with the value restores the bass immediately)... Any ideas on how could I solve this, to avoid having to play around with the settings each time I start the car :( ?????????

Do I have to root my device before I can see Android_config.xml?

I cant find it.
[Android Head-Units] berrie60:
Someone have connection and access to Android Auto ?
[Android Head-Units] MrSchlumpf:
My phone is always searching for it. But it doesn't work over WLAN or Bluetooth. But that's ok, because android auto can only use your phones GPS and that sucks in my case. I use Google maps on the headunit with a WiFi connection to the phone. Navigation works like a charm. What I miss is the hands free speech assistant.

You can use Android auto with the built in app "easy connect " or maybe it works by usb?
[Android Head-Units] berrie60:
Thanx. I have to look at easy connect.

I dont know how to connect my phone wifi ti the head unit.

I google for it.
[Android Head-Units] MrSchlumpf:
You have to make a hotspot on your phone and log the headunit in. To automate it use an app like "carspot ready" for it.
[Android Head-Units] tvladan:
Anyone has a solution for a whitelist app or mod? I'm in stock with root and need YouTube to resume playing after sleep. That option was available on my old mtcd with hal9k mod. This unit kills all proceses, even waze/maps... That is a real bugger.
[Android Head-Units] tvladan:
Have you ever found the code for this?
[Android Head-Units] tvladan:
So... This thread seems kinda dead... Probably because this stm32 units are kinda crap. Still... Does anyone have a .img rom file with the latest updates? Preferably starting with os_update_KC1E0129-P01-1.1.4.9.1_20210812 or later?

I messed with mine and lost sound (again) and none of the img's I could find online solve my sound problem...

Maybe someone can make a rkdump file form an existing running board with dsp. I would really appreciate it.

Thanks.

PX6 RK3399 STM32 Head unit - Google Drive

drive.google.com
[Android Head-Units] tvladan:
Thanks for the answer. In tried both 9 and 10 in that drive link a couple of days ago. No luck. Both boot up just fine but with no sound. I have an unbranded with DSP china 9 inch device. It came with fake 10 from the seller. (can't get a reply from the seller... So that's a dead end)

I backed up my partitions (via adb pull) but i missed the bhd one.

Flashing either img from that folder results in working system with no sound, than if i flash my backed up partitions one by one(rkdevtool via maskrom) the situation either remains the same or i get stuck at android logo.

Also those images seem to be from a boison device. I had the stock launcher with big tiles and a slightly newer model. (2021 build).
[Android Head-Units] Aplaceinthesky:

[Android Head-Units] Robbo69:
On my Xtrons PX5 this is how : Hold reset button until lights blink, release and press again for a second. If a second doesn't work try again for a little bit longer than a second.

Different unit I know but maybe worth a try.
[Android Head-Units] horsebr:
I did . Work on the same way. I just have issue with programs installed on the unit. Like YouTube , Spotify and etc. All others work fine if I use Music BT as receptor.
[Android Head-Units] mrVuHoa:
What is the benefit to root this devices?
[Android Head-Units] Robbo69:
Well for a start you could replace the original ringtone (ring.mp3 in the /system folder) with something a bit quieter and more melodious.
[Android Head-Units] mrVuHoa:
Since the software of this head unit have many limit, I am looking for some enhance after root. Any idea?
[Android Head-Units] Quincydog:
So far all I have done is root the head unit and install an ad blocker. I will probably install YouTube Vanced and Viper for Android.

After that I might want to give Majisk a try.

Have an issue with the built-in microphone not working so I can not comment on the ring tone as Bluetooth calling isn't usable for me ?.

Has anyone got a new release of the Rom for this unit?

Would like to have a way back if things F*#k up...

I am hoping that a custom Rom will be available for these HU's in the future.

Hey there!

At my Ford which has 2 wires coming from the (next to-) steering wheel control I had to connect 1 wire to system ground and the other wire I soldered to 'Key2' line. In SWC app I selected the desired button e.g. volume up then I pressed the physical button as long the HU identified the resistance then I hit save. Works for me.

P.S.: I was able to backup the manufacturers 'system apks' e.g. 'Radio', 'BT Music' etc. so if u need it for test I can share them.

Good luck! :fingers-crossed:

Hi everyone, has anyone experienced the issue where the reverse camera turns off after 20 seconds and the screen goes black, but when I turn off and start the car again, the image is back and after 20 seconds it goes off again.
[Android Head-Units] kozakerro:
Hi!

I have an issue with my PX6 based Eunavi head unit for Ford.

Suddenly while riding, the screen became white and unit became unresponsive.

Once, after I switched ignition off and on, it booted up with no issues, but after 30 minutes it again went into white screen. Since then it doesn't start anymore and only white screen is visible (which is showing initially black with white stripes, and then 'clouding' into full white).

Reverse camera doesn't work, as well as there is no audio coming from the radio. When I press and hold power button, it turns off for 10 seconds, and then it becomes white again. Pressing or holding reset button don't help - it's still the same.

I've checked all of the connection cables and outside and inside head unit but everything seems fine. I don't think it's an issue of the screen connector tape, because then I would hear the radio playing after turning it on.

Here's the video with the the current head unit behavior:

Does anyone has any idea what could be an issue?
[Android Head-Units] kozakerro:
It turned out that the problem was a CANBUS box. There were some issues with the power cable. I have checked all of the cables in the harness, re-plugged it and that helped. Hopefully that was the issue and the unit won't break again.
[Android Head-Units] pumatrax:
Hi, can you please tell me the type of male to male usb cable you used. Did you make your own?
[Android Head-Units] aphilgr1:
Just a plain male to male usb I bought from the nearby shop. I think there are easy to find. I actually got a second one with blue ends, probably meaning usb3 compatible

Thanks, I found that out and just made my own. I did order one but the one I made is working now. I am able to flash my HU but its still stuck at logo. ugh.

[Android Head-Units] pumatrax:
Yes. All working now. I used an image I found on this site for android 11 and then I applied the android 11 OTA update that my vendor sent me. And I was able to connect the radio to my computer in maskrom mode.

Hello friends

I have a rk3399 stm32 20210626 andriod 10 head unit on a cherry arrizot 5.

When i installed it almost a year ago everything was fine but for last 2 or 3 mounths, my steering wheel buttons are not wroking correctly, i mean for example when i want to reduce the volume i have to press the buttons to many time so finaly it works!

Even the physical keys on the head unit are not working smoothly as they were before!

Even i made the seller to change the canbus interface to another brand( hiworld i think) but nothing changed.

It's really annoying every time.

Hi all!

I've this update os_update_HC1E0201-P0N-1.1.4.3.1_20190904_112936.zip but whit instruction provided by Erisin I'm unable to enter recovery, how I can get it?

in the USB i have to put the entire zip? because i didn't found a .img in the archive
[Android Head-Units] OperatorB:
To enter recovery mode you can install app called 'Terminal emulator' (or similar) link then open it and type 'reboot recovery' then hit enter. In that point your HU should reboot into recovery mode. (hint: use usb keyboard there to navigate)

The .zip file can be on the local storage as is, I think. In recovery menu you can wipe (as it is advised in general) before installing a ROM. Then you go to 'Install zip' and select your zip file.

In theory that should do.

Good luck! :fingers-crossed:
[Android Head-Units] mrspazzaneve:
the first part worked, but in the recovery menu there's only some option for reboot (normal or bootloader), update (from adb or sd card), test (visual or hardware) and power off. there's not option "install zip" or from USB :(

i've tried update from SD, but after a while of black screen come back on the main page of recovery
[Android Head-Units] meshein:
I have what I believe to be the same unit being discussed in this thread. I bought the 10.1 inch, Android 9.0 headunit from Banggood. I have been trying to either root the device, or find a replacement ROM as I am experiencing issues with audio cut in/out, display brightness adjust ability, boot duration, and other UI minor issues. I am unable to access developer mode as there is no "build number" available to multi tap in settings. Wondering what methods others are using to update these units and steps taken to safely root or install new ROMs.

Kernel: STM32-20190622-11-KC6-26

OS: KC1E0101-P01-1.1.4.3.1 BLINK 161
[Android Head-Units] mrspazzaneve:
for posterity:

thanks to an Italian importer who supported me, I understood that to apply the update, simply copy the zip to the USB, connect it to the turned on radio, wait for the contents to be recognized and confirm that you want to proceed.

To enter recovery it is necessary to disconnect the power completely (it is not enough to turn the key to OFF), press and hold the reset button, reconnect the power and after about 5 seconds release the reset button, after a while recovery should appear .
[Android Head-Units] mrVuHoa:
Can you pls give me more detail? I am trying to find the way to factory or flash the rom again, by HU can not boot properly :(
[Android Head-Units] War-Rasta:
So what's the downside to these units? I've been looking at options to replace my slow RK3188 and these units seem to have top of the line specs.

10.1"screen

PX6 CPU

4GB RAM

64GB ROM

All it seems to be missing is a DAC, which would be nice to have but my current head unit doesn't have one either and it sounds ok so that's not really a deal breaker for me. From reading this post I guess these are not compatible with any of the ROMs out there but that's manageable if the stock one works fine.

I guess my main questions would be about the quality of the built in mic for hands free calling (right now most people complain when I'm on handsfree to the point that I usually avoid using it) and whether all these units are the same since I've seen a ton of them on eBay that look the same but have different branding.

[Android Head-Units] War-Rasta:
Those hurdles seem manageable considering the price difference to other units. I could add a USB fan to help with cooling and you've already added instructions on how to get better colors on the screen Would you still buy it if know what you know now or would you recommend getting a different, more expensive unit? If you've used bluetooth calling, how's the audio quality of the call?
[Android Head-Units] OperatorB:
Well, I did not have any other android HU before so I cannot compare the overall experience with others.

Its is considerable that I am a hobby hacker so buying a plug-and-play option for expensive would give less satisfaction for me.

So if you are not afraid touching this hardware - and you don't mind if software support might be poor in the future - then I can recommend it. I would buy it again. :cyclops:

FYI: I bought this for 200USD and had 20 USD refund as it was advertised as 64GB but its 32GB so even with no cooling system designed its a decent deal I think.

P.S.: I will continue testing this HU from now on and give feedback if needed.

[Android Head-Units] Robbo69:
After a couple of hot days I was concerned about the running temps of my head unit. I got this fan/heatsink from Ebay (https://www.ebay.com.au/itm/Aluminu...r-LED-Light-Cooling-Cooler-DC12V/303239591978).

I glued it to the existing heatsink with adhesive thermal paste and soldered the leads to ACC and GND connectors on the back of the main (black) socket. Works a treat - operating temperatures have dropped about 20 degrees and the fan is silent.
