I have dual E-80's. One at the helm and the other at the nav station.
My Raymarine E-80 isn't receiving boat speed & wind information from my
other Raymarine instruments. Some of the E-80 functions are effected,
such as MARPA.

Have you updated them to the latest firmware?

Yes, I have updated to 3.21

I am certain something is wrong, because I have use the MARPA feature
on either a C-80 or an E-80 on another boat before.
