the phone touts that it is "waterproof" (yeah, right), however I'm sure it will reside in a waterproof bag ... preferably in the cabin if I can get GPS signals down there.

As an alternative they said you could upload your Garmin or Magellin GPS file to their group site. sheeewt, that's too high-tech for me.

Good luck trying to find a dry area on your F18 even in light air...
