The GS HSI Kit is an all-in-one upgrade package that replaces your old mechanical heading indicator with a crisp 3.5-inch digital display. This comprehensive kit bundles the G5 electronic instrument with a GMU 11 magnetometer and a GAD 29 navigation adapter, allowing the unit to interface directly with external GPS navigators for full VOR/LOC and glideslope guidance. It slides right into a standard 3-1/8 inch panel cutout and features a built-in 4-hour backup battery for peace of mind if your electrical system drops out.
