Are you familiar with this offering from PosiMotion? The question would be is there an API which iNavX can hook into the G-Fi output? I currently use the very reliable NMEA over IP from MacENC but I can see situations where MacENC won't be available to me... and I have no intention of replacing my 1st generation iPhone.
