I use the 300XL and have flown that approach but haven't seen that before
(yet). Will be looking but don't have any thoughts other than what's been
said.

Have you tried the same approach since?

I spoke to Garmin today and they suggested that I look at the setup because
if the unit is not set up to interface with the annunciator it will not arm.
We know the wiring is good because this unit is an overhaul that replaced a
unit that did arm. This also led us to think it was a setup issue and not a
hardware issue.

I checked it today and found that there is a page in the settings called
approach and on that page is a setting called annunciator which has 2
options None/Installed. Yep, None was selected. I chose Installed and it
asked me to confirm by pressing the Arm button. I did that and it changed
to Installed.

I loaded the approach (I'm 15 miles from RUQ) and the approach armed,
problem solved.

Thanks for the suggestions.
