You will not have to make the upgrade, it is only if you want the added 
benefit of multiple constellations.

The current GPS/GLONASS constellation issues is much hairier then I 
expect that the upcomming GPS/GLONASS/GALILEO/QNSS/COMPASS system seems 
to be converging towards.

The mass-market receivers isn't there yet, but even a full-featured chip 
with massive deep P-tracking and such only costs about 20 dollars to 

I still haven't seen any normal consumer goods attempting the L1 C/A & 
L2C path... despite the gain that would give more advanced consumers in 
added navigation precission. SBAS and LBAS support are other aspects 
which still have not penetrated the market fully either.
