Thanks Darryl and others on your replies...
I spoke to CAE today and they believe it is one of 2 problems and most
likely the GPS board. I'm sending the unit back for repair and will
update the result as I find out.

The GPS engine hardware board in the unit failed. Jeff said likely
from age.

I had the same thing happen to me. You will find the new GPS engine
locks in much faster when you turn it on.

New GPS engine? Huh? The Cambridge 302 IGC approval document describes
a Garmin GPS25-LVC GPS receiver. The manufacturer cannot just change
this themselves and keep IGC approval of the flight recorder.

The actual time to get a GPS fix depends on if it was recently
operated at a different location far enough away and whether it has a
currently valid satellite almanac (and a few more things I'll
ignore). Typically when a GPS receiver like this is returned from a a
repair facility you'll see them need to get a cold fix and therefore
slower than the usual warm fix many people would see before a flight.

The time to get a cold fix times with newer generation GPS receivers
will be a lot faster than the rather old GPS engine used in the C302.
