All updated . . . .

There are two kinds of people in the world.  Those who have updated aviation databases and those who have not.  If you are one who hasn't, you will likely struggle to become one who has.  Garmin just doesn't do a good job of laying out how it is done.  There are writings and Youtube videos.  The best resources are the blogs of those who have gone before us.  I will say that once you do it, it seems so simple, you wonder why it was ever an issue in the first place.

Here is how it goes for a G1000 in a Cessna 182T with PFD and MFD at Version 12.03:

1. With power off, take all four SD cards out of the plane, noting where each goes.  It would be good if the two lower slots have actual Garmin cards of 4 GB or more, which is needed for TERRAIN and SVT.
2. Buy the new databases you wish to place in the plane, Garmin or Jeppesen.
3. Load all of the databases that you buy, except the navdata database, on the two Garmin cards that will go in the lower slots, one for the PFD and one for the MFD.  You are making duplicates, and those cards will remain in the displays.
4. Load the navdata database onto a newly formatted card.  It is appropriate to reuse the one that came out of the PFD, upper slot.
5. Erase the fourth card that came out of the MFD, upper slot, by formatting it.
6. Now back at the plane, with power off, place the navdata card into the upper slot of the PFD and turn the BATTERY switch on.  You will be prompted to update the database of the PFD
7. Once the PFD is updated, power down and move the navdata card to the MFD, upper slot.
8. Turn the BATTERY and AVIONICS 1 and 2 switches on, and you will be prompted to update the database of the MFD.
9. Once the MFD is updated, power down and move the navdata card back to the PFD.
10. Place the blank fourth card in the MFD, upper slot, for flight logging.
11. Place the remaining two cards in the lower slots of the PFD and MFD.
12. At next power up, the additional databases will be verified, and you are good to go, until next month!
