Then I get the bill. What's this? 1.0 hour labor ($75) to R&R the
gyro? I talk to my avionics tech and he says that while SigmaTek covers
the DG itself under warranty, they don't cover R&R labor.

When my GNS 430 failed I was in Tucson, AZ. Unit was installed in Ohio, 6 mo
previous. The repair shop got a new one from Garmin, installed it, and
returned the defective, all at no cost to me. I assume Garmin covered it.
