What communication interface does it use? The usual NMEA 0183?

If so you could hook it up to a laptop that has that connector and see if
the laptop receives any output from it. I suspect your NMEA 0183
com port has failed. Might even be a software failure and not a hardware
failure.

Have you upgraded the instrument's O/S lately. If so roll it back to
see if the com port works again.

Hi, Neal,

The unit is either SeaTalk or NMEA capable. It's connected to NMEA because
my prior setup was, and it became plug-n-play for all the instruments and my
computer's serial connection by attaching to the plotter's NMEA cable.

There's no SW to this unit; it used to talk to my plotter, autopilot, and
computer; now it speaks to none of them.

I pinned out the connections between the GPS and NMEA (to the plotter,
thence onward) cables and all is as it should be between those points, but
no talking to the plotter.

There have been no changes to SW or hardware in years. The "no fix" message
happened on the way back from a sailing trip with my son and his family a
few weeks ago, and I've been wrestling with this ever since.
