As I recall it was the original TH-D7A that could not parse the
extra digits after the decimal point in the lat/long on NMEA-3.0 or
some-such.  The TH-D7A(G) update fixed this.  Some people updated
their earlier HT with the new firmware by mailing it back to Kenwood
and paying something like $85?  I don't know what other updates or
bug-fixes were in the update.
