I don't think anything of the sort is at work here. GPS manufacturers had to
make their equipment updateable for aviation applications, becuause the
airport/navaid databases are volitile; that's been true since the LORAN days. 

The Northstar N1 LORAN navigator in the Cardinal that I fly must be removed and
taken to an avionics shop for updating by replacing a socketed EPROM; modern
equiment has a PCMCIA slot to accept a card that can be written from a laptop,
with current information downloaded over the Internet.  

I surely wouldn't mind being able to reprogram my 847 though. :-)
