Cheers! No more issues at all? It's driving me nuts since I've got a USB DAB stick, and FM sucks when DAB doesn't work!Yes, I did. It's my picture at the feedbacks.
For me was it a good shot.

What do you mean with sleep not longer then an hour?Not at all, so the sleep is not longer then a hour working ... I Have nearly allways whait 30 secounds
1. It's on the usb-port which is direktly from the px5-core and not over the usb-hub-chip.
When I power my device off or switch off the key my device goes for a shot time (around an hour) into the slep-mode. When I switch it after that on it is in 2 secounds back. <- it's now working -> Firmware 3.01 and in the settings for acc set to auto-sleep
The PX5-Core-Board has two usb-"ports". At my device (erisin 7429d -> XRC) goes one directly outside (it's the OTG). The other goes now to the usb gl852g-chip. From there it goes outside and to the wifi/bt-card. So its better to have the dab+ on the firstport! At my device it is the USB/3G-Port.Could you also explain the first point? I only have two USB connections on my unit, one USB, and one USB/3G which I have routed to my cabin so I can connect my TPMS and DAB stick from in the car. Is there another port, or am I misunderstanding you?
I really like google maps, but I'll install Igo Israel for when there is no internet ... Because Here without a good voice ... I can't use it.Btw for navigation I love Sygic (either the normal version or Pro), I don't use a TTS for the same reason, they suck and sound bad. I wish we could use the TTS voice from "Google Assistent", those sound a lot better.
Interesting. How does that look/work? I have two ports as well, but both of them work, or don't work. So I think mine has both of them connected to the faulty chip.The PX5-Core-Board has two usb-"ports". At my device (erisin 7429d -> XRC) goes one directly outside.

How would this work? What's the idea behind it? The description is very vague (also due to the horrible English). On which units would this work?
I don't think the temperature is the issue for me. Has been 10-14 degrees C all day for some days and still mostly no USB. Sometimes works later in the day when I use my car again. Really sucks to have a unit that relies on DAB and TPMS via USB when USB doesn't work.
The chip is too small for me to try and solder it. I don't want to ruin the unit at completely. Isn't there an easier way? Or should I just buy a new unit?

Hello
a specialized company changed the chip for me, so I fixed the problem (€ 20).
My unit is a Dasaita PX5 purchased from MTKNAVI Store on Aliexpress. The seller gave this solution!
Sorry for the english
Hello,
Chip swap to 852G was the only repair made? or did You also desolder modules as on attached pic? this solution is something new and im interested if it's working.
This is what they recommend according to your image.Hi
my seller give me the following solution without change the chip GL852G ssop28
what do you think?
thanks
Hi there,
At 4pda, they are writing, that some PX5 units have troubles with WiFi/USB below 0°C.
It looks like my Witson unit (MX2 MCU, PX5, Android 8) suffers from exactly this problem. The last days we had warm temperature and USB and WiFi worked perfectly.
Now I went outside and the issues are back. It's 0°C now here!
Can anyone confirm this issue?
At 4PDA, they suggest a fix by adding a screw-whole + screw to better fix the proccessor unit:
https://4pda.ru/forum/index.php?s=&showtopic=883219&view=findpost&p=77467642
It looks like the processor unit is only fixed by 2 and not 3 screws and especially the two most outside pins, which are responsible for wifi and usb suffer from loosing contact with cold temperature.
I'm keen on trying to hardware fix. But I'd like to know if someone has experience with this?

This is what they recommend according to your image.
To disconnect the USB POWER ENABLE digital control signal from MCU to ACP1252A/SY6288CAAC USB power enable and current limit chip - and hard wire enabling that chip.
By removing the resistances you will disconnect that control line. By connecting the 4-5 points you connects the USB POWER ENable control pin directly to input 5VDC voltage line. This will enable USB power at the USB output connectors as soon as 5V main power line will be present in the head unit (regardless of MCU).
It could help, if the problem lies in the USB power.
As always, try it at your own risk
I can post schematics here for those who are interested, but can't directly - some local forum rules forbids me to do.
So schematics is here: ibb.co/YPcrjvM
same problem here with a px5 board.
But - is it possible that bt still works fine and wifi not? I think, if the GL850 is the cause then both wouldn' work.
WIth me it's "only" wifi and usb.
Hello
Can you make a photo of crystal and send it here?
Dasaita change something in board design (usb hub for sure) and currently doesn't exhibit cold temp bug.
Info confirmed with my friend with new unit.
I have older unit (from September) with older usb hub and need to make an upgrade.

Hi there, will comment in the thread you linked. I have running that fix with tasker already but still have partial drops of the host controller. I'm also working on a tasker task to switch WiFi on as soon as it gets off.
