FYI: Nuvi 200 "Type B" GPS Chipset Firmware Update

There is a chipset firmware update available, for the "Type B" GPS chips
(MTX); it's avail ONLY via webupdater, not by manual download.

Note not all nuvi 200's use this chipset, some earlier units use the
Sirfstar (if yours does it'll say "SirfStar" on the startup screen; type B
says nothing specific). It updates 2.10B to 2.30B.

Google around for more info on the various chipsets used inside these
units (there are 3).
