Vantage questions

1) It appears as though SIU airplanes will get all of the PFD engine instruments that DAU planes see on the PFD, presumably via a high speed connection between them. Correct? I'm assuming this doesn't include Ammeter information, since that's funky with the manual ammeter switch in SIU planes. What about DALT? That doesn’t normally show with an SIU on the MFD, but will it with Vantage, where the PFD and MFD can communicate?

2) The Installation manual says the MFD now fully supports ADS-B In traffic and weather via RS232. If I currently have this connection from my transponder to an IFD, which in turn shares this information with a second IFD, do I need to connect anything else, or will IFD connected RS232 traffic/weather automatically propagate to the Vantage displays? Is there any reason one might need to connect a Skywatch device directly to the MFD, if the Skywatch already feeds the GTX 345 transponder, which produces blended TIS and Active traffic? The Skywatch gets position information from the PFD, right?

3) It appears as though the PFD can set modes on the DFC90 via touching the PFD screen. How does one do this, and does this offer the ability to add new features, like VNAV, as a PFD soft key for the DFC90 in the future?

Very excited to see these new displays get released; can't wait for mine!
