Dual ByNav PCB v2 versions

I built a ByNav setup with PCB v2 all via usb for spring of 21, used it but then haven’t used steering on that tractor since. Looking to get steering going again, just curious what version and setup I should use as so much has changed. I could update to UDP and change the ByNav to UDP as well if there is any major advantages to that. I was getting a 2nd GPS string out of the ByNav at the time to feed GPS to a planter so wouldn’t mind having the same ability to get a GPS out signal, I thought I read I could get this from Agio now? Anyways just curious of all thoughts of best version and updates I should do, thanks
