Hi, I'm pretty new to this scene and was hoping for some support and guidance from the community. I have recently purchased a 2nd hand car which had a PX5 head unit. I will post the device details below, but I was hoping you could point me in the right direction to download a newer and compatible firmware/mcu for my unit. I'm used to flash custom rom/firmwares on android mobile phones so I do understand the process itself quite well, it's just the firmware/mcu compatibility with this device that I'm unsure of. Thank you in advance for the support.
