Last week my G3X flashed X's all over the screen and then went blank and rebooted in flight. The next day it just rebooted inflight.

Thanks to Jon Delamarter for his help in contacting Garmin for the solution. Turned out to be a corrupt data card. Garmin suggested flying with the data card removed. After 3 hours flying on 2 flights, it ran normally. Bought new data cards and problem solved. I did learn from the G3X manual that Garmin recommends using 3 separate cards for flight data, database updates and software updates.

Thanks Jon for the quick response and solution!!!
