This post may be of interest to those with Exec Glass (G3X Touch) and a G5 EFIS.

Garmin added a new audio alert "MISCOMPARE" which is sounded when the GDU software detects a miscompare between G5 and GSU 25 attitude data or air data. In my FX-3, which uses a GTR 200 and no remote audio panel, the new alert was truncated (front half of the alert was not audible).

I advised Garmin of this problem but found a solution today. I changed GTR 200 squelch level for AUX-1 input from default 30% to 10%.

I do not know if the remote audio panel used in some Carbon Cubs has a similar squelch configuration and would have the same alert message truncation.
