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.
