Sounds to me like the problem is in the "back end" of the software, and
would be independent of the "front end" (ie, which receiver).

I agree with this. I am worrying if the problem is shown in the
Map276C. Some of the new "land" units have SIRF gps engines, in place
of our traditional "legacy gps Garmin receivers", and could not have
the problem. If the problem is with the legacy gps software, it
could affect many (if not all) marine models like mine 276C.
