2 INSTALLATION OVERVIEW
2.1 Introduction
This section provides hardware equipment information for installing the GMC 7XX and related hardware.
Installation of the GMC 7XX should follow the aircraft TC or STC requirements. Cabling is fabricated
by the installing agency to fit each particular aircraft. The guidance of FAA advisory circulars AC 43.13-
1B and AC 43.13-2A, where applicable, may be found useful for making retro-fit installations that
comply with FAA regulations. Refer to the G1000 System Installation Manual, Garmin part number
190-00303-00 for further details on the mechanical aspects.
2.2 Installation Materials
The GMC 7XX is available as a single unit under the following part number:
