Welcome and congratulations on your plans to go with a Cirrus!
As Dennis said, you will actually find your questions answered “inside” COPA, and A LOT MORE!
You can go enroll, login, go to the search and type:
prebuy OR inspection
subscription AND garmin AND 430
Or just peruse the almost a million posts which are sorted by category, type of plane, type of activity… etc.
So, hopefully will see you soon inside of the fence.
P.S.: as a matter of testing it I just searched for “prebuy OR inspection” and found this which happens to be on the public side of the forum!
