Hi George,

I'm sorry for the delay getting an answer to your question. I sell and
support Glide Navigator II which is the latest version of what was
Pocket-NAV. I forwarded your question to Chip Garner (GN II author) and his
response is below.
"GPRMC message for location, GPGGA if possible, this gives the GPS altitude
and allows differential final glide altitude."

You may want to consider getting Glide Navigator II as there a several nice
new features added since the days of Pocket-NAV such as the highlighting of
reachable airports on the map screen.

Good Soaring,

I'm trying to get a Compaq Aero 1530 with PocketNav to receive NMEA
output from a Colibri logger so that it can display the moving map.
When I tried it for the first time in flight the PocketNav message was
"No NMEA Data" and it went into simulator mode. Can anyone tell me
what sentences to select in the Colibri's setup menu in order to get
this to work?
