Updating data on the Garmin Perspective system
After changing from the Avidyne system to the Cirrus Perspective (G1000) system, I had to relearn an important part of owning an airplane: how to update all the data the systems use. There's even more data in the Perspective, including AOPA directory data and more charts. In this walkthrough, I make use of the Jeppesen app for Apple OS X: JDM . It has worked well for me, though I did need to call Jeppesen when I first set this up to get my subscriptions fixed up. They gave great customer support when I did.
