Yeah, i agree...in the feature list it looks like interface with SL30/40 is planned for a future upgrade, though I might expect this to fully control the SL30/40 from skyview. I would hope to use some of that functionaly to send data to the A210 (NMEA + VHF out). The A210 also has a serial tx, but I have no idea what data it might send out or why, except that the Garmin documentation for the 396 says to setup the GPS connected to the SL30/40 with TIS-IN or Aviation-IN and NMEA+VHF out. I gues I'd have to find out what's common between TIS and Aviation that a GPS might be interested in, and a COM radio might have...I was thinking NAV data, but my A210 doesn't have NAV data, but still has the Tx out...ok, I'm getting off topic now maybe.
This is just to fill the A210 channel memory slots with nearby frequencies from the navigation database in skyview (or other aviation GPS such as Garmin 396).
Not a critcal thing by any means, especially for local flying...but a nice to have for the cross-country stuff.
Sorry that I'm mixing up information from the A210 with the SL30/40...but the A210 documentation is terribly incomplete (the GPS hookup wiring isn't even in the product documentation, its a separate document that Icom emailed to me, and doesn't include the data formats required), so I'm having to fill in the blanks with the way other products transfer same information.
