[GPSNavX]

Seems like this DSC NMEA stuff is still be sorted out. It will be a while before there is much connectivity between VHF radios and Nav software. It's not that it is difficult to support such functionality in a nav app. The difficulty is with getting the NMEA data to the Mac. Easy enough to plug in a GPS receiver or AIS receiver, but now add instruments, autopilot, VHF radio, etc and you have allot of connections. Sure you can use a NMEA multiplexor, but from what I have seen they are not up to par yet with this new ITU data NMEA sentences.

I am happy to add more NMEA capability to GPSNavX, but I need it spelled out specifically in a specification and I need to the ability to test a configuration. In otherwords the solution needs to be universal in that it will work with all DSC VHF radios.
