I just bought a PX5 unit, which seemed to be working perfectly until I finished installing it into my car and now it has become unresponsive with a black screen and a yellow rhombus with an exclamation point in the middle (unable to upload image as new user).
If I turn off the ignition, it will turn the stereo off and the android screen briefly shows before going into sleep. None of the buttons are allowing me to get past the screen and in to android. The reset button seems to do nothing, android is definitely running in the background, just unsure as to why this screen will not close. Any ideas?
Hi, I think I saw a yellow rhombus with an exclamation point when I was installing my radio and rear view camera was not connected to the radio. I think that it is a warning about missing video signal when radio is displaying live feed from a rear view camera.
So, one explanation for your issue could be that the radio thinks you are reversing, and the rear view camera is not connected to the radio. If I understand it right, radio can switch to rear view camera display mode based on two conditions 1) canbus information 2) +12v trigger signal.
For the condition 2), you could check that nothing is unintentional connected to reverse detect wire. If that does not help, then you could perhaps try to disable reverse view feature in the configuration menu before installing the radio to the car and/or find a working canbus configuration settings.
Please notice that I'm a beginner with Android head units and your problem might well be something totally different!!
Thanks for your reply. Some of your post seems to relate to my issue definitely, I think it is linked to the rear view camera which is currently disconnected. However I am unable to get into any configuration options. None of the buttons/resets I try get me past the exclamation screen, I can only see android once I turn off my ignition when it tells me it is closing down. None of the various reset button combinations seem to do anything with my head unit either, can't seem to reset it properly. Its strange, I will reattach the camera tomorrow and see if that brings any joy. I don't know anything about this stuff myself but I am wondering if I did something to the head unit to brick the non-android side somehow.
Edit: Unfortunately reattaching the camera did not change anything.
Update. I have managed to find a way in to the Android side if I connect my phone via bluetooth to the stereo, it then lets me use the split screen function via the top bar menu to put the warning screen other screen to the side, however whenever I touch the screen or attempt to use the android interface, my stereo goes back to the warning screen, none of my inputs via the stereo buttons or the touch screen seem to be registering with the Android side? Very confused. I have also tried as many button combination resets I can find and I have not been able to successfully get into the recovery menu, or any change except rebooting.
Was your unit professionally installed?
Also, what did the re-seller suggest when you contacted them for support?
No the unit was not professionally installed. I am not sure how I've become stuck with the problem. I made some minor changes in factory settings but nothing I thought would of caused this. The seller is yet to respond and its been a couple of days, but I have requested the hardware reset methods for this unit or any other solutions.

Check the reverse wire on the back of the unit...if necessary disconnect it to ensure no reverse signal is received.
If your unit can boot into android normally then you will have to figure out why the reverse wire is receiving signal .
Check your connectors to avoid any of them to be loose.

Everything has been disconnected from the unit except the power cable to car and and canbus, from what I can tell nothing is loose. Unit will not boot without the canbus box whatsoever, not sure if that is meant to happen.

Yes, canbus decoder need to be connected for power up the HU. If you dont need the decoder box you need rewire the harness.
I think I am going to have to request a refund and return it. Still no reply from the reseller and I am not sure what else I can try, everything that is not needed to power it has now been removed. I can't send links or else I would update the thread with a video of the touch/physical buttons being completely unresponsive even when I manage to get to Android. The unit has definitely developed a fault and I am unable to reset it. Admittedly it could be my fault somehow as it was working for the first few boots, but unless they give me something to try I am just going to have to send it back.
Quick bump. Has anyone got any further ideas? I bought off Aliexpress so contact with the seller is slow and painful, they do not seem to understand the issue and just keep telling me to disconnect all wires and reconnect. Which has been done many times. If anyone wants to post a link to the video for me I would be happy to send them it privately.

I would start a dispute with them. I had a device that they sent with similar problems and plenty of issues, which they would not help with or would not understand. Best option is to dispute to get a new device or a full refund. Could you send the video?

Yeh I have a dispute open currently, just was hoping it would inspire the seller to actually offer up a working way of resetting the device. Had to add link below seperately as needed to be ten or most posts.

The stereo defaults as the warning image black screen and I can only get android up using the multiwindow button with a long press. Then the android side will not register any input and will keep trying to put the black screen to the front.
Update: I have been told by Aliexpress I can have a partial refund and keep the unit, or a full refund if I return to China. Anyone have any ideas how I would go about resetting the unit if I took the partial refund? To be honest I think my only option is to return it and get the full amount back but any ideas would be welcome! Shipping to China and awaiting a refund is going to take weeks, would rather just get it working if possible.
deano35: any progres? I have the same problem as you. This is my post from PX5 MTCD/E Head Unit Discussion Thread
" Hi , I have https://s.click.aliexpress.com/e/DtwdJIt its px5, Mtce_gs_v2.90c. Now I have a little problem with rear camera. I bought reverse camera and tried to connect it into front camera input(I was curious how it would look like) and since then its stuck on camera view. Even after disconnecting camera. Only solution was disable "prohibit reverse" in factory settings menu, but with "prohibit reverse" disabled is obviously not showing reverse camera when I gear the reverse down. Everything is shown in this video. https://photos.app.goo.gl/XbYUHApzT8qTezkq6 Thanks for any advice. "
Take a look on the video, its similar as yours.
Hi,
I installed this HU in my car a month ago and I still have not gotten it to work properly. My main problem is that the unit reboots randomly and does not turn on again.
I have tested the reset button and checked all the wiring. I have connected the 12V direct battery and the adapter for the steering wheel gives me the 12V ACC.
It seems that the radio goes into some form of protection until it suddenly decides to restart.
I really do not know what else to check. If I modify some parameter in the factory settings, it asks to restart, it only shuts down but does not turn on.
Yesterday afternoon it worked correctly but this morning it has not started.
any ideas?
These are my specs:
Car: Alfa Romeo 159 (2012 year)
HU: Xtrons TE706PL
MCU: MTCE_GS_V2.88_3
steering controls: Connects2 CTSAR002.2 + CTMULTILEAD.2 Patch Lead
I'm experiencing the same issues with my PX5 / CSN2 headunit from Klyde. Sometimes the HU won't come out of standby, the screen remaining black and buttons not reacting at all (but with LED backlight). If I had FM radio before turning off, it will start playing audio only in the background. Turning off the car engine triggers a restart, as if it entered some unrecoverable state.

First...update the rom and mcu to the latest available
Try
Second...disconnect the connects2 and use the unit without that canbus to ensure there is incompatibility issues. Try

Well, in my case the unit doens't start, nothing, no led, no sound... I think the problem is that the unit is not able to make a cold start after going into deep sleep

I can't update the frimware if the device doesn't start...
I'll try, but it is not easy because my car doesn't have 12V ACC so I need the connects interface to get the power.

To test, I would do this.. Connect the acc direct to battery.... The deck should turn on.. Reboot the deck while it's on. If it boots back up... Then the above poster is probably correct. Your module is not working correctly and not giving a proper acc signal.
The unit was connected with ACC wire connected to the Connects2 adapter. But yesterday I connected the unit directly to the car only the wires; ground, 12V battery and 12V ACC. The device started and worked fine. Turn off the car and five hours later the device didn't started. Today 20 hours later the device doesn't start either I tried to disconnected everything and connect again but the problem continue.
I think the problem is, the device is not able to do a cold boot after to turn off the radio. How to do a factory default reset? maybe this fix the problem.
I connected the device to direct battery and the first time worked but now it isn't able to start....
Hello ,
two weeks ago I bought that unit for my Mazda CX-5.
The problem i have is, when I start the car in the morning, no USB Port is available.
when I start the car later again, all ports can be used.
The seller said, it will be an inkompatible USB chip (my chip is GL850G) and I should replace the GL852G for the GL850G.
It´s no contact problem, I tested all possibilities.
Is it possible that the reason could be is a firmware problem.
My englisch is not very well, so please be answer easy for me.
thank you
Sven
Update to hal9k ROM, it's an hardware bug. The hal9k ROM resets the usb hub when HU boots.

Hello,
That's enough, and works?
Thank you

Hi
I have the same problem on my Dasaita!
the problem occurs only with the dab module connected to the cable with 2 usb, while the single USB cable, which I connected the 4G wi-fi router, always works.
If I will installed the hal9k ROM, could I fix the problem?
thanks
I purchased a Dasaita PX5 Android 8.0 headunt for a NISSAN X-Trail 2016 last August. Since autumn I've more or less weekly (sometimes daily) a big problem: the head unit restarts during nomal operation conditions and sometimes it even restarts up to 10 times!
After resetting the unit by pressing the reset button the system mostly runs fine. I think the main problem is the USB chip on board. I've read that there's an USB-chip issue. Dasaita suggests to change the chip by your own. Why they do not ship new updated boards?
Hi guys,
I just bought a car unit android 8, but the screen sometimes (90% of times) looks flipped left-to-right. Sometimes is also flipped upsdide-down+left-to-right.
And sometimes I get the screen working as it should be, flawlessly, until I do not restart the car.
The defect appears from the beginning, right from the initial logo, and it remains also if I try to reset the unit. Also when I get the "boot" text menu, it appears flipped as everything. (edit - in addition, the touch layer still working in the right way, so I cannot easily understand what I'm touching on the screen, and this makes everything more complicate)
The unit is a px5, 4GB RAM, 8-core, the MCU is MTCE_XRC_V2.93_1.
I didn't already tried to overwrite the android files, because I'm trying to get some assistance from the producer. Anyway the product is coming from China, so I guess I will have to do it by myself. Until now, I rebooted, reset, cleaned, changed startup settings, and spent a lot of time in doing and re-doing all these tasks, but the unit still like at the beginning.
My question for you: do you think is it hardware problem, or can be fixed with a firmware update?
Do you have any suggestion, setting or trick in order to solve the problem?
Thank you in advance for your help.
Kind regards
It looks like a hardware problem indeed. The touchscreen 'digitizer' is apart from the display in the front. You could try if the ribbon cable inside the radio is firmly connected to the mainboard i guess. Otherwise i think a new screen..?
I will have the same issue with this same units. I write to selller , he send me a new spare part responsible for displaying the image.
I have the same problem. What is the spare part that solve this probem? Thank you in advance.
Hello. I just bought PX6 Android 10 car multimedia unit. It had no sound and steering control, so I thought I would update MCU and system. No I still not only didin't cleared the issues, but the screen is off to the side (lost about 20% screen), touch is out of normal operation, and have verson unmatched warning.....
Could someone help?
It was
MCU MTCE_HXD_V3.56_3
It's all touch, so is there a way to boot to recovery mode? I managed once, but can't repeat it, RST looks like not working and I'm desperated...
