2.2 Description of Alteration
The GTN navigators are a family of aviation panel mounted retro-fit products. GTN units utilize a
touchscreen as the primary control interface. Traditional knobs and buttons have been minimized to
simplify access to the color multi-function display (MFD), NAV and COM transceiver, and GPS/WAAS
navigator functions.
The GTN 625/635/650 Navigators (Garmin Touch Navigation) are a family of 2.65-inch tall aviation panel
mounted retro-fit products that are intended to supersede the Garmin 400W Series Navigators. The GTN
6XX product family consists of the GTN 625 GPS/WAAS navigator, the GTN 635 GPS/WAAS/COM
navigator, and the GTN 650 GPS/WAAS/NAV/COM navigator.
The GTN 725/750 Navigators (Garmin Touch Navigation) are a family of 6.00-inch tall aviation panel
mounted retro-fit products that are intended to supersede the Garmin 500W Series Navigators. The GTN
7XX product family consists of the GTN 725 GPS/WAAS navigator, and the GTN 750
GPS/WAAS/NAV/COM navigator.

The optional GMA 35 is an audio panel with a Marker Beacon receiver. The GMA 35 in conjunction with
a GTN 7XX provide full audio panel capability, for communication and navigation radios, headsets,
microphones, and speakers. The GMA 35c provides the functionality of the GMA 35, with the capability to
pair Bluetooth™ audio sources. This enables the distribution of audio to ICS positions when using a
compatible iOS or Android™ device. The GMA 35c supports up to ten stored devices and one active
Bluetooth device. The GMA 35 is mounted in a notch behind the GTN 7XX to free up mounting space in
the flight deck instrument panel.
The optional Aerospace Optics HTAWS terrain caution/warning indicator and HTAWS status annunciation
are required for those installations that have the HTAWS function enabled on the GTN (unless the
rotorcraft is equipped with a GDU 620 or GDU 700/1060). These annunciators serve as the visual
indication of a terrain/obstacle caution or warning alert as well as HTAWS failure and HTAWS inhibit
status.
The Flight Stream 510 is a wireless-enabled data card that is inserted into the GTN data card slot to allow
wireless database synchronization with personal electronic devices (PEDs). Synchronized information is
then disseminated to various LRUs through their existing GTN interface connections.
2.3 Control, Operating, and Testing Information
See Garmin 190-01004-03 Rev. D, “GTN 625/635/650 Pilot’s Guide” and Garmin 190-01007-03 Rev. D,
“GTN 725/750 Pilot’s Guide” for information on how to operate the system in normal mode.
See the Section 3 of the GTN 6XX/7XX PART 27 AML STC MAINTENANCE MANUAL, Section 3 for
details on how to operate and access configuration mode and diagnostic pages, and Section 2.1 for
document part numbers. See Section 6 for general ground checks and system test procedures
See GTN 6XX/7XX PART 27 AML STC MAINTENANCE MANUAL for a system description.
2.4 Servicing Information
None.
In the event of system failure, troubleshoot the GTN 6XX/7XX,GMA 35, and Flight Stream 510 in
accordance with Section 4 of the GTN 6XX/7XX PART 27 AML STC MAINTENANCE MANUAL.
2.5 Periodic Maintenance
The GTN and GMA 35 are designed to detect internal failures. A thorough self-test is executed
automatically upon application of power to the units, and built-in tests (BIT) are continuously executed.
Detected errors are indicated as failure annunciations, system messages, or a combination of the two.
Operation of the GTN 6XX/7XX and GMA 35 is not permitted unless the inspections described in this
section have been completed within time intervals prescribed in Table 1. All antennas connected to the
GTN should be maintained in accordance with maintenance and inspection data appropriate for the
antenna installation.
