Is the GPS data update essential, or just a one off? i.e. once I've locked, is the GPS data essentially automatically updated and as such I should experience a quick lock next time around? If not, where should I put the Ephemeris.cab file?

Thanks again
Obviously the device stores the latest position, so if you start from the same place the fix will be quite fast, when you boot it up again.

Extract the Ephemeris.CAB archive and copy the files into the "ephem" folder.
