Avidyne told me a few times they are really only interested in retrofitting the pre-G1000 Cirruses (a few thousand of those, perhaps) with the DFC90.
But also their story is the same every year, and to me (as a businessman) their general behaviour is that of a financially struggling company.
Like it or not, Honeywell handed the GA market to Garmin on a plate, and Garmin have now eaten everybody's lunch
But Garmin are not going to be certifying their -700 autopilot (which appears to be very good, though I would regard it as very unproven long-term) for too many types. They want to sell it with the G1000, mainly, and similar products.
