Garmin Introduces Color Mode Controller for GFC 600

Garmin is pleased to announce the GMC 605C, a new color display mode controller for the GFC™ 600 digital autopilot.

The GMC 605C mode controller features a larger, sunlightreadable, color Liquid Crystal Display (LCD) screen that enhances the display of mode annunciations. The addition of color mode annunciations allows pilots to more easily differentiate between active and armed modes shown on the display. Mode annunciations are split into three sections on the display –– lateral modes, autopilot status, and vertical modes. This presentation aligns the mode controller display with the annunciations seen on Garmin TXi™ Flight Displays for easier reference by the pilot.

Garmin expects to receive initial FAA STC approval in August and will be initially approved for airframes listed in the table below. Existing aircraft already approved for GFC 600 not listed in the table below will be transitioning to the GMC 605C with a future STC update. Additionally, installation of the GMC 605C in approved aircraft will require interface to an approved Garmin Flight Display and GTN Series Navigator and will require the installation of the Yaw Servo.

Initial Aircraft Approved to Transition to GMC 605C:

  • Beechcraft: 36, A36, A36TC 95-B55, 95-B55A, 95-C55, 95-C55A, D55, D55A, E55, E55A 58, 58A, 58P, 58PA, 58TC, 58TCA C90, C90-1, C90A, C90B, C90SE, C90GT, C90GTi, E90, F90 200, 200C, A200, A200CT, B200C
  • Cessna: 208, 208B P210N 340, 340A 414A, 421C, 425, 441
  • Piper: PA-46-310P, PA-46-350P (JetProp) PA-46-310P, PA-46-350P (Piston) PA-46-500TP (Meridian)

Upgrade to the new GMC 605C

Existing GMC 605 customers can upgrade to the newly announced GMC 605C for a discounted price. Through the end of 2024, the GMC 605C will be available for only $5,995 with the trade-in of a qualifying GMC 605. The GMC 605C is a slide-in replacement for the GMC 605, but does require a Garmin Flight Display, GTN Navigator, and Yaw servo to be installed to meet installation requirements. Garmin anticipates having a similar trade in program for airframes not initially approved once they receive STC approval.

Qualifying trade-ins:

  • GMC 605 [P/N 011-02967-00]
  • GMC 605 [P/N 011-02967-02]
