From Kitplanes:
So let’s dive in. Garmin has one physical configuration of the instrument itself, with variations based on what is in the box and which bits of software are enabled. It breaks down to an attitude indicator (ADI) starting at $3995; this is known as the GI 275 ADAHRS. A somewhat de-contented version of that same box can be used as a course deviation indicator (CDI) or multifunction display (MFD); it’s called the GI 275 Base and sells for $3195. A third version is the GI 275 ADAHRS+AP, selling for $4495, which has all the functions of the ADAHRS unit as well as a supplementary circuit board to provide both digital and analog outputs to drive certified autopilots. Oh, and there’s actually a fourth version, which combines the GI 275 Basic display/processor head with a remote box (either the GEA 24 or GEA 110) for integrating with engine and airframe probes. Garmin’s goal was that some combination of these instruments would produce a whole-airplane solution in 31/8-inch instruments. Where this meets the needs of Experimentals better aligns with those looking to update older aircraft without having to gut the panel and start over.
Sounds to me like the basic MFD version does what you want.
