Hi Curt and Frederic, My wife gave me a Garmin GPSmap 496 for Christmas. Nice wife, huh! Anyway, I recalled this thread and want to confirm whether either of you have had success with the --AV400 beyond what was reported in this thread. Did you get FlightGear to drive the Garmin GPS III Pilot from Linux? I have ordered the serial interface cable from Garmin and will be trying to drive the 496 in simulation mode from FlightGear when it arrives in about 7 to 10 days.
Besides the "fun", this would be a great way to become very comfortable with the 496 and all its features w/o the pressure of using it in a real flight plan. I cannot pause the real pa24 to figure out what I did wrong with the GPS keypad. -Dave Frederic Bouvier wrote: > Curt, > > Frederic Bouvier wrote : > >> What option do you use to make it working ?
