I have a JY Head unit that the GPS slot has failed. The 2nd slot (SD) is OK. I've done a visual and confirmed the connections. It's really not a huge deal but since I'm going to be inside the unit soon doing a PX3 to PX5 upgrade I thought I would replace the board if available and not too expensive.
Any sources where to get parts? Anyone have an otherwise dead unit good for parts?

Hi MTCD Fellows,
is there anybody who upgraded his MTCD from PX3 to PX5 who wants to sell met the old PX3 board?
mine is broken, there is no sound coming out of it anymore.
why not just buy a PX5 to replace it? They're much better! I have one, but I'm in New Zealand..
i dont want to pay any customs taxes. everytime i order from china i have to pay 25%+
my device is broken because the DAC is defective. i ordered a new one already from desaita., beacuse i hat bluetooth and wifi issues prior to the defective board.
i want to resurrect the old erisin one and sell it on ebay. it does not matter on ebay if it is px5 or px3 IMHO

Both Bluetooth and and WiFi are Not on the PX3 board! They are on the main MCU board. Those sound issues might pretty much be from the MCU board also. Have you tried with another PX board to check if things actually work with it?
Ive got one ill sell you, just took it out of my system. Works well.
I have one too.. worked when I removed it
So my head unit ( Joying JY-UL135 ) stopped turning on. I went through various troubleshooting steps and the conclusion I and Joying support came to was that the coreboard has failed. They will send me a replacement one for a reasonable cost but I have to send the old one back direct to China which would bring the cost up to "ehhh" territory. And that assumes the package will get there and the deposit will be returned.
I have the original RK1388 1GB setup which was incredibly slow and disappointing. I asked Joying if it was possible to get a PX5 replacement because of how dissatisfied I've been with the unit. Joying told me that my unit was not compatible with the PX5 boards. I guess I was confused about the coreboard stuff, because I thought that RK1388 1GB board was the "PX3" that gets referred to here on the forums.
My questions are as follows:
* Is that correct that I cannot install an upgraded (more RAM specifically) board in the JY-UL135 unit? The PX5 boards are not compatible?
* Is there a place I can order coreboards domestically (US) to compare the price?
* Is there anything I can check/do with the coreboard to try and get it working again? I am very comfortable soldering, using a multimeter, etc. I've thought about using a heatgun to try and get the solder to reseat.
edit:
Update:
I had it confirmed on another forum that the PX5 RK1388 replacement boards are compatible with this specific head unit. It is the Joying-specific PX5 boards that are not compatible since they do not sell the appropriate type, and that is what Joying support meant by it wouldn't work.
I've ordered an octa-core board with 4Gb RAM and 32Gb storage.
Do they come with an OS already installed?
If they do, given I'm upgrading from 1Gb PX3 will I be alright sticking with the stock ROM? I'm assuming it's going to be way faster than the PX3 that's in it right now and I'm not that bothered about customisation. I only installed a custom ROM to get some speed improvements before.

Mine came with an OS but I upgraded right to 7.1.2 from 5 I believe.

I ordered it from Ali Express but it's going to take a while to be delivered from China to the UK so I can#'t say that it is working as I haven't got it yet.
I bought this one which should be fine:
https://www.aliexpress.com/item/Oct...D-Android-5-1-system-Upgrade/32865743307.html
So this arrived yesterday and I fitted it immediately. My only issue is that the connector on the GPS aerial was just slightly larger on the inside of the unit than the one on the PX3 board. I didn't have time to desolder the one offthe old board to swap it out so I've had to leave the DVD/CD Player out of the unit because the connector was in the way.
It's not a problem for me as I don't use CDs anyway.
Wow, it's a revelation. Totally different experience. I've now got auto-sleep which means almost instant restart, the external microphone appears to be working now and the speed is just fantastic compared to the PX3.
I'm not even going to need to put a custom ROM on as it's more than fast enough as it came.

I'm thinking of doing the same thing, since my head unit is painfully slow. But the link you pasted above seems to have lapsed. Did you buy from WITSON?
i.e. this one? alixepress.com /item/WITSON-PX3-Quad-Core-2GB-RAM-16GB-Flash-Coreboard-For-Android-DVD-Android-5-1-A5XXX/32820356300.html
(Darn site won't let me post URL until I'm out of probation!)
Thanks!
Does anyone want to buy a PX5 board?
I'd likely sell mine if someone was interested.

Is there a way to know for sure this will work in my Xtrons android px5 unit?
Good afternoon,
I was wondering if anyone could tell me please if the core board from this unit:
https://www.aliexpress.com/item/4000132959961.html
would work and boot inside one of these:
https://www.ebay.co.uk/itm/7-Android-7-1-Car-Stereo-Radio-DVD-Player-GPS-DAB-OBD-Head-Unit-for-Seat-Ibiza/153679322081?fits=Model%3AIbiza&hash=item23c8005be1:g:WoIAAOSwvchdntjk
i have the 1gb version of the one listed on ebay and am possibly able to buy the aliexpress one secondhand cheaper than buying a standalone coreboard.
Kind Regards
Les Mack
Yes, the PX3 board can be exchanged for a PX5 or even PX6 board
I bricked my MTCE radio while mcu updating and now it doesn't work, buttons don't light up. Also i can't repair it by installing new MCU by st-link v2.
If It helps when i buy a new px5 or px6 coreboard? MCU is on this coreboard?
Cut losses and buy a superior FYT UIS7862 unit. See FYT forums.
Alternatively, you could send the unit to me and I can try recovery - no charge, only return freight.
Where to buy it? I search Google and nothing. It fits in citroen DS3?
Where are you from? Maybe it is a good option to send it to you.

Cheaper than buying a SOM and mainboard, but understand if you don't.
