The AIS data will flow over from the FA-150 to the FAR21X7 or NavNet Network (whichever is the case). Heading and Position will STILL need to be wired into the commercial FA-150 unit due to IMO requirements. It will NOT get this info over the network. By design some restrictions apply when using IMO devices. If you fail to wire in heading and GPS it will cause errors on the FA150 and other unwanted negative effects.
