I have an older PX3 unit (i think, it's a rockchip rk3188 + 1gb ram, made by Joying) I'd like to upgrade. I've found a PX5 board: https://www.aliexpress.com/item/32820356300.html and have been reading stories about BT/WIFI not working. I'm handy with a soldering iron, so I can potentially change out the BT/WIFI module if it doesn't, I'm assuming I'd swap it with this: https://www.aliexpress.com/i/32953209958.html if I run in to problems? Also, is there anything I'd need to do to the unit before swapping out the boards? flash anything? Is there a better board to upgrade to? I've read about PX6 boards but can't seem to find em on aliexpress. In all honesty i think the PX5 would be a sufficient upgrade, since this PX3 is just stupid slow. I don't care about 3g/4g dongles, just really want something that will run headunit reloaded for android auto.
I took these photos of the unit information, let me know if there's anything else you need. As far as I know its an MTCD unit.

Yes you can upgrade the SOM and WIFI/BT module with the items you list. This is exactly what I did.
Thanks. Is there any prep to do beforehand? or is it just drop in and go? I'll have to solder on that wifi/bt board i suppose, but I mean software wise?
Suggest updating your MCU to latest available. The supplier should ship the SOM with Android installed.
Do you know which one is the latest for my unit? According to the list of cross compatible MCU's it should be 2.56?
I have a new PX5 SOM for sale and also a bricked one if someone is confident using OTG mod to unbrick it. I post to UK only
Hi there as well
Please allow me to give you some advice.
1. The last post in this thread dates back to almost a year ago, so there is little chance of you getting the replies you are hoping for.
2. That gets me to the second point.
You could start a new thread in the Q&A section, with exactly that question you have posted today. Might get you some attention and ideally an answer to your question
Good luck!
Cheers,
mrjuniork
