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.

Removal and replacement of the following items. See Section
The display backlight LEDs are rated by the manufacturer as
requires service.
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 35 is mounted in a notch behind the GTN 7XX to free up mounting
space in the flight deck instrument panel. Rotorcraft model specific installation of the GTN is documented
in GTN 6XX/7XX PART 27 AML STC INSTALLATION MANUAL and Garmin 190-01007-H9 Rev. 1, “GTN
6XX/7XX Navigator Installation, Eurocopter EC 130B4/T2 Rotorcraft”.
2.3 Control, Operating, and Testing Information
See Garmin 190-01004-03 Rev. D, “GTN 625/635/650 Pilot’s Guide” and 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 SYSTEM MAINTENANCE MANUAL, Section
3 for details on how to operate and access configuration mode and diagnostic pages, and Section 1.5 for
document part numbers. See Section 6 for general ground checks and system test procedures.
See GTN 6XX/7XX PART 27 AM L STC SY ST E M MAI N T ENA N CE MAN U AL for a system description.
2.4 Servicing Information
None. In the event of system failure, troubleshoot the GTN 6XX/7XX and GMA 35 in accordance with
Section 4 of the GTN 6X X/7XX PART 27 AML STC SYSTEM 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.

Regular planned replacement is not necessary. The GTN will
display a low battery’ message when replacement is required.
Once the low battery message is displayed, the battery should
be replaced within 1 to 2 months. If the battery is not replaced
and becomes totally discharged, the GTN unit will remain fully
operational, but the GPS signal acquisition time may be
increased. There is no loss of function or accuracy of the GTN
unit with a dead battery. The battery must be replaced by the
Garmin factory repair station or factory authorized repair

1. Remove the GTN and GMA 35 (if installed) from the
mounting rack(s)
2. Remove the backplate assembly from the rack(s), such that
the harnesses are disconnected.
NOTE
For GTN 7XX only, if the GMA 35 is installed, it must be
removed from its rack and the GMA 35 backplate assembly
must be removed prior to performing Step 3. When a GMA 35
bonding check is planned, perform the GMA 35 bonding check
prior to reinstalling the GTN backplate assembly to the rack.
3. Measure the resistance between each mounting rack and
nearby exposed portion of metallic structure and verify that
the resistance is less than or equal to 10 milliohms.
In the event of bonding test failure, remove the rack and verify
that the countersunk areas around the holes, in the rack that
are used to attach the rack, are free of corrosion or any other
debris. Clean the countersunk areas using an approved
solvent per Eurocopter Standard Practices Manual (MTC 2002-07-401). Reattach the rack to the rails in the panel. Reverify the resistance between the mounting rack and nearby
exposed portion of aircraft metallic structure and ensure that
the resistance is less than or equal to 2.5 milliohms.
