I have had a Dasaita PX6 Max10 installed in one of my vehicles for 6 plus months without a single issue.

So happy with it that I recommended to a friend. Exact same unit.

This one has yet to be installed.

After purchasing through Amazon, we received an email and link to new firmware.I bench tested and updated to the latest firmware.

Now EVERY time you remove 12v from the accessory red wire, the unit auto-launches whatever is assigned as the default navigation. When you re-apply 12v to the red wire, it fast boots and launches Zlink. Close Zlink and the default navigation is running. Close that and you finally get to the home screen.

I have emailed Dasaita a bunch of times. The are NOT responding.

It looks like this new unit is going back to Amazon.

Anybody recommend a more reliable Android unit with 10" screen?
[MTCD Android Head Units General] storm14994:
Hi everyone, I am new here and I recently bought the Dasaita HA5632-MAX10-CP-HD for my 2016 Rav4. However, after a couple days of use, my unit's screen is now flickering and not fitting (as pictures show). I tried to contact the seller (Official Store from Aliexpress) but have not get any reply yet due to their Lunar New Year now in China. My unit runs Android 10 out of the box with the exact same MCU and software update as the quote, so I guess they are the newest version now. I am wondering if anyone has these problems and whether or not they are related to hardware? Thank you.Dasaita PX6 MAX10 flickering and not fit
[MTCD Android Head Units General] storm14994:
Hi there, how did you get in contact with the Dasaita? I messaged them 2 days ago in Aliexpress but no reply yet :(
[MTCD Android Head Units General] Bob_Sanders:
Did you do those updates or did it come that way from the factory?

I ask because you have to be careful to get the right update. There are different screen resolutions for the Dasaita units and you have to make sure you get the right one.

Does the screen flicker all the time or does it flicker only after it is warm?
[MTCD Android Head Units General] JigenKing:
I'm getting this exact same issue. My screen started to flicker today and I'm on the same MCU version 3.71.

It also came with 3.71 from the factory.
[MTCD Android Head Units General] storm14994:
Everything comes from factory, I have not done any update or firmware flashing yet. The flicker screen issue happens randomly to me and usually after the screen out-of-fit happens, but the out-of-fit (sorry I dont know how to call that) problem always there after about 5 to 15 mins driving and it will be normal if I shut the car off for A WHILE then turn on again. But if I turn the car of then turn on right away, it is still there. These things happen to mine unit just 2 days ago, it worked normally before that.
[MTCD Android Head Units General] storm14994:
Do you have any issue with out-of-fit screen? Kind of the top of the screen appear in the bottom like mine. Which unit did you get? Is it PX6 MAX10 as well?
[MTCD Android Head Units General] Bob_Sanders:
How hot is the machine getting?
[MTCD Android Head Units General] Paolojoy:
sorry but then these problems are due to the last update of 11/01/2021? with MCU 3.71? thank you
[MTCD Android Head Units General] storm14994:
From the screen itself I feel it is not hot at all, I do not know how hot in the back of the HU since I get it installed but right now at the place I am living the temp is dropping down to minus °C. Hopefully it is something related to the new software and MCU because the out-of-fit problem happens quite exact at the same amount of time the HU is turned on.
[MTCD Android Head Units General] storm14994:
Speaking of the temperature, can I use the app from google play store to check it? Thanks
[MTCD Android Head Units General] storm14994:
I have no idea because I have not get any feedback from Dasaita yet.
[MTCD Android Head Units General] Bob_Sanders:
Yes. There are lots of apps that will display your cpu and operating temps. I know that when my unit starts getting hot the FM radio starts skipping.... and units are getting hotter this time of year because it's Winter in most places and everyone is running their heat (which gets the inside of the dash hot.)

If your machine is overheating it will do strange things, so make sure that is not your problem

I post my internal temperature right on the front screen so I can see it at all times:
[MTCD Android Head Units General] storm14994:
I see what you mean. That could be the problem, have you ever had the same issue like me? And as you say, your FM skipping problem will be gone after the temperature inside the car cool down?
[MTCD Android Head Units General] JigenKing:
I don't have my backup camera connected to it.....but it happened after a few minutes of driving the first time....and then almost instantly after turning the car on and off.
[MTCD Android Head Units General] Bob_Sanders:
I have never had a screen issue, but the fm radio starts acting like your screen.... off,on,off,on,off,on about once every couple of seconds when the machine is hot. If I cool it down it's good again.

So, it may be your problem, it may not be. Just something to consider.
[MTCD Android Head Units General] storm14994:
Did you have the heater turned on at that time? Do you try to contact the seller?
[MTCD Android Head Units General] storm14994:
You might be right. I tried to test it today with the heater off and it run normally for about 30 mins of driving. Then I checked again with the heater on (around 22*C) and that happened again. I feel like my HU now is very sensitive to heat since there was no problem at all for the first couple days of use even with the heater on. I bet there was problem with the head unit’s screen which makes it too sensitive to the heat.
[MTCD Android Head Units General] JigenKing:
No I don't have my heater on when I'm driving.....the manufacturer emailed me back on the problem and told me to install MTCE 3.69 and system update 20201217....will try that over the next few days
[MTCD Android Head Units General] jlbooth:
I was having the same issue when I was using Headunit Reloaded app to do Android Auto. Found that disabling the Google app on the headunit resolved the double google assistant popping up. Locate the Google app in the Settings...Apps.. and choose disable.

It doesn't seem to have this problem when I use ZLink v4.0.14 for Android auto, so disabling Google app was not necessary. The December SYGAV firmware brought ZLink to 4.0.14. I would venture that the 20210111 update brings ZLink to 4.0.14 as well (have not loaded the Dasaita firmware, so just guessing on ths).

The SYGAV PX6 (it is MTCE_HA) unit is virtually identical to the Dasaita PX6 and the firmwares are compatible.
[MTCD Android Head Units General] storm14994:
Yes the Zlink on Dasaita one is 4.0.14 for the newest firmware
[MTCD Android Head Units General] storm14994:
Hopefully that will solve our problem. Please let me know if you have any update. I tried to contact Dasaita but nobody reply yet.
[MTCD Android Head Units General] marchnz:
$10 on against odds :)
[MTCD Android Head Units General] storm14994:
Sorry I did not get what you mean
[MTCD Android Head Units General] JigenKing:
Did you buy on amazon? Their amazon contact replies fairly often.
[MTCD Android Head Units General] storm14994:
I bought it from Dasaita Official Store on Aliexpress. Is your unit Dasaita or Sygav?
[MTCD Android Head Units General] JigenKing:
Its a Dasaita
[MTCD Android Head Units General] VovaSRB:
I was have version from Dezember, it was work all good, whit version from january my camera flicker..

I was install again decembar version, all is again good..
[MTCD Android Head Units General] storm14994:
Thank you for your sharing. So, basically you can downgrade the Android Software and the MCU? Is the December version you say the Android Software one?
[MTCD Android Head Units General] storm14994:
Was your unit also sent from China?
[MTCD Android Head Units General] storm14994:
How is your HU now? Does the downgrade firmware version help?
[MTCD Android Head Units General] mpj220:
Please update if you are able to downgrade firmware on the Dasaita.

My current MCU and firmware are auto-launching both Z-Link and default navigation on boot up.

I tried to install an older firmware posted in this thread but, the unit stops, claims it cannot be downgraded, followed by exiting to bootloader.

I have contacted Dasaita many, many, many times over the past 2 weeks with no response.

They finally responded today with a link to an MCU image file.

It was the same image file I currently have. I loaded it anyway.

Still has the same problem.
[MTCD Android Head Units General] win2k3pro:
Hello. Maybe someone could upload (CMU AND SYSTEM) and help me with my unit..

It should be:

This would help me very very much :/

I updated to 1024x600 damn it.. and have no original files.
[MTCD Android Head Units General] win2k3pro:
How to use dmcu.ext? I have wrong screen resolution and can't figure it out how to restore to correct (i need 1280x720)
[MTCD Android Head Units General] win2k3pro:
Damn thank you so much for authot of this post my screen is back and runing!!!
[MTCD Android Head Units General] JigenKing:
I found out it still does the same....

I did play around with the settings while it was doing it, and found out it might be a problem with screen brightness, or at least the controller for it. While my screen was turning on and off I clicked on the brightness setting and turned it to the lowest setting. That stopped the flickering for the time being. It takes awhile for me to replicate the flickering issue since it takes like 15+ minutes.

I'm still in contact with Dasaita about it. I think it might be a firmware issue controlling the back light.
[MTCD Android Head Units General] storm14994:
Hi, I got the reply from Dasaita yesterday told me to try unplug and reinstall HU connections. I tried but nothing changed even I have reset the Factory settings. So, the seller told me to send the unit back for a replacement. It will take a while since my HU was sent from China to Canada. I will keep you update when the replacement one arrived.
[MTCD Android Head Units General] storm14994:
For the flickering screen issue, I am pretty sure that is a software bug as my unit does the same thing and the problem is solved when you reduce the screen brightness. But for my case the screen has out-of-fit issue most of the time which is really annoying to use. The seller from "dasaita Official Store" on Aliexpress told me to send it back to them and they will send me a new one.
[MTCD Android Head Units General] mpj220:
I uploaded a video of what my Dasaita PX6 Max10 is doing.

The video was requested as Dasaita either doesn't believe me or there may be something lost in translation.

If anyone has any ideas, please feel free to share.

Thanks
[MTCD Android Head Units General] marchnz:
Dasaita do not monitor this thread, you should contact them directly.
[MTCD Android Head Units General] JigenKing:
I just got the same message. They asked me to buy a new unit and ship back the current one.
[MTCD Android Head Units General] mpj220:
The link was emailed to Dasaita days ago.

Since the customer service responses have been very slow and not helpful, I posted here in hopes that others may have experienced the same problem and could possibly share.
[MTCD Android Head Units General] lim-popo:
Try this MCU

MTCE_HA_V3.71.zip

drive.google.com
[MTCD Android Head Units General] mpj220:
Thanks for the info.

Yes, I also thought that was the setting causing this. I went through each of those settings and also make certain that I close all background apps prior to removing accessory power.

When in the "off" setting: Apply power to accessory - unit stays off until you press the power button. Default navigation still auto launches on power up and power off.

When in the "on" setting: The video was taken in this state.

Did not try the "last used"?? setting. I figured since default navigation auto launches on power off, that would be what it launches on power up.

I will test all 3 states after work.
[MTCD Android Head Units General] mpj220:
Thanks, will give it a test drive after work.
[MTCD Android Head Units General] lim-popo:
I have completely the same unit in my Citroen DS4... But to be honest I'm using custom ROM from Malaysk and don't have this kond of isuue at all.

1. Try to update MCU that I send

2. If nothing will change try to install this ROM (light version) and test it again (if fine then you can buy an full version if not then you can return to stock) Sow...

[MTCD Android Head Units General] mpj220:
Thanks!

I also have 2 of the same Dasaita units. One has been installed for 6 months with no issues.

When the second one was purchased from Amazon, Dasaita contacted via email and said that an MCU and firmware update was needed. I used the same "stock" link that you posted and updated both units.

The older unit works fine. The new one is doing this "auto launch" of navigation.

I contacted Dasaita and they claimed I was using the wrong firmware and sent this via email:

"Hi, Mark Johnson

you need to update the system.

Here you go for the update link:

MAX10

PX6 10.0 HA3_rk3399_10.0_ota(20201214) https://www.sendspace.com/pro/dl/f3gyol

PX6 android 10 （1113）

https://drive.google.com/file/d/1rO-wBK8rvVZsXT_5IjN3MyuMY00utZZX/view?usp=sharing

Please download, then ONLY put that zip format file to the usb (format the usb before you use it to make sure only one file in the usb)."

I updated with the first file and the unit was doing the same thing.

I tried to update with the second file and the unit begins upgrade and then gives an error that says I cannot downgrade firmware. After the error, it defaults to recovery menu.

Quick question on the Malaysk firmware:

Does this firmware have the Z-Link app? Or some way to use Android Auto?

Thanks!
[MTCD Android Head Units General] marchnz:
None of these head units are Android Auto. What you are referring to is an app that attempts screen mirroring.
[MTCD Android Head Units General] lim-popo:
Yes, it contains Z-Link... But you need to consider that Android Auto works only via cable connection (just in case...)

Check last update by Malaysk

[MTCD Android Head Units General] storm14994:
Mine case is they will send me the new one to replace my old HU that I returned to them. The funny thing here is I have to pay for Shipping fee and ship it to US instead of China, I think they might have a warehouse there. From their Return Policy, the shipping fee is bear between Seller and Buyer but the seller told me this is customer responsibility :(
[MTCD Android Head Units General] mpj220:
I am using a different launcher as well.

Launchair 2

It's simple - a very stock Android look.

It displays backgrounds very well to match the vehicle I am putting it into.

If you zoom in on the skull hydro-graphics, I was able to do some photo-shopping to have wallpaper match.
[MTCD Android Head Units General] mpj220:
I got a chance to install that latest MCU just now.

Unfortunately, it did not cure my problem. It still auto-launches default navigation on both power up and power down.

AI also tried booting to the bootloader, doing a full wipe/factory reset, followed with full wipe of cache partition.

Still have same results......and more. It is back to also launching Z-Link on power up and default navigation.

At this point, I have spent far too much time on this unit. 3 different MCU, 3 different factory firmware.

Dasaita appears to be missing in action - several more emails sent to them with a link to the youtube video - no response.

Time for this one to go home. Sending back to Amazon.

Will order another of the same unit and cross fingers.

I made a video after updating MCU and resetting everything.
[MTCD Android Head Units General] lim-popo:
Wait a second... What about your Factory setting (126)??? Try to made some changes there! So far as I know, there is some option for Z-Link (100%), not sure about Navigation (my car is in garage now... need walk... I'll check it when visiting my local post office and will let you know) I will made video for you. Try first Factory settings!!!

As the last chanse, try to install Malaysk MOD (if not solve your issue the return to stock and send it back)

Regards

[MTCD Android Head Units General] mpj220:
Went through all of the factory settings, Z-Link settings, etc.

I have another identical unit, that was running the same MCU and firmware. That unit has been close to perfect since day 1. Only issue that occasionally happens is with Z-Link linked as Android Auto. Once in a while, it disconnects and a loud, high pitched, noise tests the limits of my amps. speakers, and ears. This has only happened about a half dozen times.

Went through all of the factory menu settings on my good unit (took pics) and made certain this new unit was exactly the same.

I bought both through Amazon Prime so, since this one is new and Amazon handles returns, I figure I have given it plenty of effort.

Dasaita did finally respond to my email with the linked youtube video.

They supplied a link for the MCU v3.71d version, along with another firmware version.

At this point, after 21 days of trying to make a new unit work as it should, 4 different MCU's, 3 firmware packages(4th on deck).....I am throwing in the towel.

I don't want to go past Amazon's "free return" policy. It states 30 days.
[MTCD Android Head Units General] lim-popo:
Here's my video

Might be helpful (I hope so

)
[MTCD Android Head Units General] mpj220:
Thank you!

Most all of my settings match yours.

The only thing that I have not tried is to select NO on the "car play" setting. Both of my units are set to Z-Link.

At work now - will verify all when I get home.

Regards!
[MTCD Android Head Units General] lim-popo:
Good luck... Crossing fingers :)

What is the version of Z-Link app in your HU???
[MTCD Android Head Units General] lim-popo:
May I ask you to share the firmware that Dasaita has send you??? You can upload to your G-Drive for e.g. If it's possible for sure?

Just got a replacement unit, its kinda weird that the one I ordered in January and the one that came today has different housings for the screen. Makes me wonder if that was the reason why I had screen flickering issues, different panels / backlights for the screens. The one with the black back is the newer unit.
[MTCD Android Head Units General] JigenKing:
Does anyone know of a way to restart the headunit without turning the car on and off? Occasionally my bluetooth won't initialize and it won't connect to any devices unless i turn the car off and on again.
[MTCD Android Head Units General] marchnz:
In factory settings "password" dialogue, enter hctreboot
[MTCD Android Head Units General] Bob_Sanders:
Every Dasaita I have seen has a rest hole somewhere on the front panel. Stick a paperclip in the hole and hold the button until the front button lights flash, then release. The head unit will reboot.
[MTCD Android Head Units General] goygfamily:
Hello expert i would like to check is it possible to update my current android version 9 to 10
[MTCD Android Head Units General] Bob_Sanders:
I wouldn't. You're asking for trouble. I have had both 9 and 10 and there really isn't enough difference to warrant the risk of an update. A lot can go wrong for almost no gain at all
[MTCD Android Head Units General] marchnz:
Quite right.

From what I can tell there is a fallacious driven want to update to get a higher number and the belief you're getting something "better" :)
[MTCD Android Head Units General] jlbooth:
And it's not like we get any kind of revision notes and even if we did, would they be useful when new firmware versions are released. Often the updates break way more than they fix. I'm tempted to give that March Dasaita PX6 release a try but thing is that I have a pretty good working system now.

As they say, if it ain't broke...don't install new firmware to break it!!
[MTCD Android Head Units General] Xybertecnic:
I emailed them many times, sometimes they respond, most of the times they don't, guess it was my lucky day :)
[MTCD Android Head Units General] Xybertecnic:
for some reason last week my unit was also auto launching Zlink every time I switched on the car, it had never done this before, since you can't delete it, tried deleting the storage and cache, and also tried just deleting the directory with file explorer, but didn't help. Then looked in the factory settings, and there you can just disable the app, just like apple carplay, now problem is solved. Still weird that this suddenly happened since I have the unit in my car for months now. Only problem is still the rebooting of the unit now and then, only seems to happen just a few minutes after driving away, same for cold or hot weather.
