Thanks for that answer Meindert. It is as I suspected, and I am
somewhat annoyed that the RayMarine gadgetry doesn't automatically talk

NMEA. to other components. I thought the entire reason for NMEA
standard is to have different brand components communicating.
Raymarine has ignored that.

Well, NMEA has some limitations and manufacturers also like to bind their
customers to their system.

My Garmin has wiring that says "DSC". Can I assume that it will work
just by wiring it into my ICom VHF?

Yes. If you feed the NMEA Out from the Garmin to the VHF, it should pick up
the location info.

This stuff is fascinating, but it doesn't seem like there's much
information available about it. Do you know of any books on this
subject?

Not really. I've tried to make a web page that explains a bit about NMEA
connections and the need for multiplexers. See
www.shipmodul.com/en/nmea.html for some info.
