I have had an issue with my unit since I received it in May 2019. When I initially installed it, it up it worked OK, CD, Radio and USB all played fine as did the navigation.
So I remove the car key and call it a day. When I return and put my key in the slot, I could hear the units disc transport spinning up and reading the TOC and then whatever the last track being played could be heard, I could control volume etc from the steering wheel but there was no display and no amount of button pressing will bring it back.
I got a cocktail stick and hit the reset button on the front and hey presto the display returned OK. This also works if I unplug it from the cars loom and then reconnect it (but that is just a faff too far).
However as soon as I remove the key at the end of a journey and then return to it and put my key in, I have no display but it will be playing whatever it was when I left it previously.
It has on VERY RARE occasions functioned as expected but it is so infrequent that I cannot recall when that last occured.
The supplier did send a replacement CANBUS Decoder and a replacement screen but neither fixed the issue.
Any ideas?

Since your unit seems to work after a reset, maybe disabling the auto sleep (fast boot) feature to force the unit to do a full boot every time you start the car might help. The setting may be found in the Extra settings menu (for Dasaita units it's under Settings...Car...Extra settings). I have mine set to fully power off the system 30 seconds after I turn the car off, thus a full boot up every time I start the car.
Full boot up would be better than having to reach for the reset every time you want to go for a drive.
We have a winner!
Thank you so very much jlbooth for your reply and suggestion.
Only wish I'd posted earlier.
Cheers

Glad to be of assistance to you Dave. I've had a lot less problems with various things on my own head unit since disabling fast boot.

Hello Guys,
I really need some insight on this problem:
I have a KLD (http://www.eonon.com/Car-GPS/Specific-Car-GPS/Mazda/GA5151.html) unit for some time now, but since September it wasn't in my car because I was preparing an audio upgrade. As one of the last steps I've checked out the HU and I wanted to upgrade to the latest MCU&FW, but the unit wouldn't turn on. Since it's on my "workbench" I've checked the cables, fuse, the external PSU, everything i could, but it did not help. The unit worked flawlessly in the car and on the workbench 2 months ago. Nothing changed. Now it won't turn on, not even the fan at the back of the unit. The screen and the button backlights are also off.
The one confusing part is, when I push the power button with reset for a few seconds, the unit comes to life, and goes into recovery! I can flash a ROM, clear the cache, etc., but when I reboot the unit from the menu, it turns off, then the button backlights flash once, but nothing else happens. The unit stays turned off.
So far I've checked:
- Fuse
- External PSU
- Power button
- Replaced the SOM (The unit is RK3066 originally, I'm using it with RK3188)
- Tried different ROMs
- Disconnected the DVD drive
Nothing helped. I can get into recovery, but I can't boot the unit, no matter what SOM (or what ROM) I use. I would really appreciate some help, because I ran out of ideas.
Thanks in advence!

Ok, the big conclusion is to use the multimeter first. Magically, ACC was not even close to 12v. Switched to another PSU, everything works.
Ok, I installed the new Joying 10.1" VW head unit in my car the other day, and it's working pretty good, however I'm having a couple of issues. I installed Malaysk's ROM onto it and still working through setting everything up the way I want it, but I'm having 2 issues I can't figure out, and they are driving me nuts.
Wifi: Whenever the unit reboots, the WiFi is disabled. I have to manually re-enable it every time.
12-Hour Time: Every time the unit reboots, the time reverts back to 24-hour time.
Anyone know what I can do to fix these issues? Getting rather annoying having to switch them every time the unit boots up.
Thanks

Sounds like the 12+ and ACC connections are swapped.
Thanks for the reply, but the unit is switched on Via Can-Bus. There is no ACC wire. It powers on and off just fine when I start and shut off the car.

Then your 12+ is not constant.
Yep it is, verified with a volt meter, 12volt constant stays hot, even went out and checked after my car had been off for over an hour just to make sure... I shouldn't have said there is no ACC wire, ACC is supplied by the Can-Bus adapter.
As far as the wiring goes, I'm confident all of that is wired correctly. I used to install car stereos as a job for 5 years, and this is the 3rd head unit in this vehicle. I'm an Android enthusiast, and definitely know my way around the system, even though this is my 1st Android head unit I've dealt with.
The 12-Hour time issue was happening before I installed the ROM on it, but the WiFi issue didn't start until after I installed the ROM.
Ok, thats a puzzler then. My observations have been that wi-fi will turn off and 24 hour set every time power is lost on the 12+ line. It seems independent of rom used, would happen on the stock rom and on a older version of Malaysk's I'm currently using.
Well, for whatever reason today the settings never reverted back. I don't remember changing anything, but I did go through every single menu and sub menu in the settings section. Oh well, fingers crossed everything stays set, because this head unit is perfect for me now!
I have the same issue + no bluetooth. I have a YINUO 1024x600 Quad-Core RK3188 and it's doing the WIFI OFF, 24 HR, NO BT.
Hi,
I recently updated my rk3188 MTCB-YM from 4.4.4 to dsa’s 5.1.1 ROM. All went well with the update. After a couple of weeks, I found the ROM was starting to run quite slow and was almost unusable - except if you kept the unit on for a long time. It was like it was loading a lot of things for a long time and once that was done, it became responsive immediately instead of being delayed to button presses etc.
So I decided to boot into recovery and do a wipe all/factory reset. My unit does not have physical buttons or a gps sd card slot. None of the usual boot into recovery options work so I use an app to reboot into recovery. I started this app and chose the correct option. At the time I did this, the radio was playing. The screen went black and the stayed like that with the radio still playing. The lights on the unit are still on but nothing works - no response at all. I have turned the car off and left it off overnight. When I turn the car back on, the radio starts playing again immediately. (This would normally take a little time while it boots up, so the unit is obviously stuck). As I cannot do any of the reset/recovery options - is there anything I can do? I haven’t removed the unit to see if it is possible to short the pins as I don’t have access to a bench power supply and have limited skills. But I will try this if there are no other options. I also haven’t removed the battery terminal to cut power yet. That was going to be my next test. But wanted to see if there was any advice before I do this.
EDIT: I took the plunge and disconnected the battery, and the unit started back up again.
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....
Hi All,
I recently updated MCU and firmware to latest firmware on Dasaita's site:
MCU V3.69c：https://www.sendspace.com/pro/dl/pf1zz4
Android 10 Update PX6 HA3_rk3399_10.0_ota(20201217) https://www.sendspace.com/pro/dl/rbsz9o
Since update, I have a strange problem. When I turn the accessory to off, the volume bar appears and increases 5 levels.
Example: volume start at 5, turn acc off, volume increases to 10 before power off. Turn acc back on (volume at 10), turn acc off, volume increases to 15 before power off.
My fear is that, should I have music at a high volume when I turn off the vehicle and turn the vehicle back on, I could see voice coils flying past my head.
Since it is an open cockpit (no roof) vehicle, I do tend to have volume very loud.
I have checked factory settings for boot volume - it is turned off.
Thank for any input.
Well, it goes from bad to worse.
I contacted Dasaita and told them I had updated to the MCU and firmware listed in the post above. Both are what is listed as current firmware on Dasaita's website.
They emailed back and said I had incorrect firmware for the Max10. They gave me the following links (direct copy from email):
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
So.....
I updated with the first file.
Now the unit has different problems.
Upon removing accessory power, the unit auto launches the default navigation app, and then powers down.
On power up, the default navigation auto launches, followed by an error message that "Zlink has stopped".
This happens EVERY power up.
So, I tried to update with the second file. Update fails claiming that the unit cannot downgrade to this file.
This sucks for me. I told a friend how great my system works and this unit was actually going to be installed in his vehicle tomorrow.
Any ideas?
Try disabling zlink.
I tried everything.
Emailed Dasaita for a bit of help as the problem only happens on the new unit.
I updated both units with the same firmware/mcu. My radio had no problems (been installed for 6 months).
This new radio continues to be a problem.
I re-updated with the same firmware. Several times as each time seamed to give new problems. SDK errors, wouldn't launch play store.
Each time I did select to wipe from the upgrade menu.
Currently, initial power and boot up appears fine.
When I remove accessory, the unit auto-launches the default navigation program prior to going to sleep. If I apply acc power within 30 seconds, the unit powers on and auto-launches Zlink. If I wait more than 30 seconds for full power off, apply acc power, the unit boots and auto launches navigation as that was the last active program.
Is it possible to completely reformat and load the update from scratch?
It just seems odd since I have 2 identical units on the same firmware yet only one is doing this.

If you update android there is an option „wipe...“ maybe you check this.

"wipe data" was selected with each update.
I ended up returning the unit for a new one.
No troubles with the new one.
