I have ordered the following for it's replacement:https://www.amazon.ca/DTECH-RS485-RS422-Serial-Adapter/dp/B06WGQDV7Z
I have the Dtech one working on my system with a Garmin chartplotter and Raymarine Autopilot. I did have to connect - to + and vice versa though, but I think that will depend on the VHF
Was that specific to send nmea GPS to the VHF radio?

I did the first wiring diagram you posted with negative results. I will try the second one and hop it does the trick.
