The iPhone app "GPS 2 IP" linked here ..

http://itunes.apple.com/us/app/gps-2-ip/...25926?mt=8

Allows the iPhone GPS to be used as the GPS receiver for MacENC.

Setup:

1) Launch GPS 2 IP on your iPhone

2) Set to "ON"

3) Launch MacENC

4) Select "TCP/IP" on the "GPS" menu

5) Enter the IP Address shown in GPS 2 IP in the MacENC TCP/IP NMEA Data Client Host (i.e. 10.0.1.8)

6) Enter the Port shown in GPS 2 IP in the MacENC TCP/IP NMEA Data Client Port (i.e. 11123)

7) Select "Enable" in the MacENC TCP/IP NMEA Data Client

8) If the connection is successful the circular indicator in MacENC TCP/IP NMEA Data Client will turn green AND the GPS 2 IP Connected clients will list your Macs IP address (i.e. 10.0.1.6)

9) To see the lat/lon/sog/cog select "Connect" on the MacENC "GPS" menu. Set the Type to IP Only in the GPS panel Settings drawer.

GPS 2 IP has the option to run in the background. This is selected in the GPS 2 IP "Settings".


Note: While this is a solution, we still prefer a USGlobalSat BU-353 USB GPS for Mac use.
