[CA] SPX computer conecting to Garmin 4212

[tgsail1]

Chuck- I tried the unit yesterday. The SPX version is the latest at 3.05, however the p70 version is 1.06. I was able to find the SPX version number by using the Garmin 741 version list. I confirmed that the SPX will not enter track mode unless the N0183 is connected. I believe it would be a good idea to update the p70 firmware. I think it is necessary to remove it and take it to a dealer nearby with access to a Raymarine MFD, correct?

If I disconnect the G741 GPS from the STNG backbone, (and reconnect through a gateway device as recommended), I believe I will lose the ability to interrogate devices on the STNG net from the GPS. The GPS provides a wide range of information beyond the limited set available by N0183 (eg see the last paragraph).

I could set up the p70/SPX on a standalone ST network, but now I'm using the ITC-5/i70s for wind and speed, so I do not believe that is an option anymore, unless perhaps I use a ST/STNG converter to feed ST data to the SPX.
