snip if you are going to update your PDA the new one should be self
contained including the GPS. /snip

Dave, that would not work for me -- the PDA software I use (WinPilot,
GNII or SeeYou Mobile, depending on the coin toss) all use ASI,
pressure altitude, and vario sentences from the 302. Hence, WinPilot
ADV would work with only GPS/NMEA, but WinPilot PRO the others would
not.
