Figure 3-7, Garmin Unit S/N Location - Garmin G1000 Nxi System Maintenance Manual

Determining Installed Garmin Units
Use the table in Appendix A to determine what the unit part number is based on the unit's serial
number reported on the MFD Aux - System Status page in Normal mode or PFD1 System
Status page in Config mode. This table lists the units that have different loader card option files
so the installer can choose the correct file without requiring the unit to be physically inspected.
