Solution to G3X Checklist issues

[Rick Junkin]

If you're having problems with getting your checklist to display on the G3X, look at your .ace file in the Garmin Checklist Editor and make sure you didn't create any "empty checklists". You have to have at least one checklist step under each checklist header or the G3X will give you a "No valid checklist present", or something like that, on the checklist page. For instance, if you created a Ground Emergencies group and created an Engine Fire checklist header in that group, you have to enter at least one step under the Engine Fire header.

Hopefully that's the solution for the folks having issues.

@Oscar Avalle, this solution wasn't in the troubleshooting info I sent you.

It may be an easier first step for some folks to use the Ace-Editor app on an iPad or Mac to review their checklist file to look for an empty checklist. The app will open the checklist file, but as you page through the checklists the app will crash if you come upon an empty checklist. You'll still need to use the PC based Garmin Checklist Editor or the web based EFIS Editor at https://rdamazio.github.io/efis-editor/ to fix the file by either deleting the empty checklist header or adding a place-holder step to the empty checklist.
