Never flown a Garmin kitted airplane, like the looks of it. BUT the new Garmin for the 'SOV light' and the Ten has to be Part 25 approved, which is, apparently, a different game than 23 certifications. It might be that some functions won´t work.
Anyhow, anythings better than the Honeywell crap I have to deal with every day right now. An EPIC pile of horse manure...
For interested parties: Phase 5.0 will not be introduced, but 5.1 or 5.2. Development phase has NOW been closed and certification is in progress. Q1 they (Cessna) say. They haven't said what year....
