Well, I'll be honest with you - the only thing I know about Furuno
Naxtex is their receiver - I've never worked with Furuno data streams.
I do know that on the Raymarine C system which I had on my Contenders,
ZDA can be selected for date/time input (I just looked it up in the
manual).

On my Furuno NavNet system NMEA sentences can be turned on and off via
the system setup panels. Check the installation guide.
