2.1 Equipment Descriptions

2.1.1 GTN Xi Navigators and GMA 35

NOTE

For pinouts and wiring diagrams, refer to GTN Xi Part 23 AML STC Installation Manual (P/N 190-01007-C0).

The GTN Xi SBAS navigators are a family of aviation panel-mounted retrofit products. The following sections will describe the available functions for each unit in the GTN Xi family.

2.1.1.1 GTN 6XX Xi

The GTN 6XX Xi navigators are a family of panel-mounted GPS/NAV/COM navigators that include the GTN 625Xi, GTN 635Xi, and GTN 650Xi. GTN 6XX Xi units are 6.25 inches wide and 2.65 inches tall. They feature an 834 × 370 pixel color LCD touchscreen.

The GTN 625Xi is a GPS/SBAS unit that meets the requirements of TSO-C146c and may be approved for IFR en route, terminal, oceanic, non-precision, and precision approach operations when installed in accordance with the instructions in the manuals referenced in the GTN AML STC. The GTN 635Xi includes all of the features of the GTN 625Xi in addition to an airborne VHF/COM transceiver. The GTN 650Xi includes all of the features of the GTN 635Xi in addition to an airborne VOR/localizer (LOC) receiver and glideslope (G/S) receiver.

2.1.1.2 GTN 7XX Xi

The GTN 7XX Xi navigators are a family of panel-mounted GPS/NAV/COM navigators that include the GTN 725Xi and GTN 750Xi. GTN 7XX Xi units are 6.25 inches wide and 6.00 inches tall. They feature an 834 × 986 pixel color LCD touchscreen.

The GTN 725Xi is a GPS/SBAS unit that meets the requirements of TSO-C146c and may be approved for IFR en route, terminal, oceanic, non-precision, and precision approach operations when installed in accordance with the instructions in the manuals referenced in the GTN AML STC. The GTN 750Xi includes all of the features of the GTN 725Xi in addition to an airborne VHF communications transceiver and airborne VOR/localizer (LOC) and glideslope (G/S) receivers. Additionally, GTN 7XX Xi units have the capability to remotely control GMA 35 audio panel functions.

2.1.1.3 GMA 35 Audio Panel

The GMA 35 Audio Panel is a remote-mounted marker beacon receiver and audio panel with a six-position intercom system (ICS) that interfaces to the communications and navigation radios, headsets, microphones, and speakers. The ICS includes electronic cabin noise de-emphasis, two stereo music inputs, and independent pilot/co-pilot/passenger volume controls. The intercom provides three selectable isolation modes. A pilot-selectable cabin speaker output can be used to listen to the selected aircraft radios or to broadcast PA announcements.

The audio panel relies on a GTN 7XX Xi to control and display the audio functions. The GMA 35 interfaces to the GTN 7XX Xi through RS-232 for control and display of audio panel functions.

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.

190-01007-C1 GTN Xi Part 23 AML STC Maintenance Manual Rev. 1 Page 2-2

2.1.1.4 Flight Stream 210

NOTE

Only one Flight Stream system should be installed per aircraft.

NOTE

Flight Stream supports connection to one navigator at a time.

The Flight Stream 210 interfaces to the GTN Xi through RS-232 for attitude information, flight plan information, and GPS PVT. The information displays on a portable electronic device (PED). The Flight Stream interfaces to the GDL 88 through RS-422 and the GDL 69 through RS-232.

2.1.1.5 Flight Stream 510

The Flight Stream 510 is a wireless-enabled data card that is inserted into the GTN data card slot.

The Flight Stream 510 interfaces to the GTN Xi by replacing the front-loaded data card to allow wireless database synchronization with PEDs. Synchronized information is then disseminated to various LRUs through their existing GTN interface connections.

2.1.2 NAV Antenna Cable Splitter

The navigation antenna cable splitter (Garmin P/N 013-00112-00) is used for installations involving dual VHF navigation capable GTNs or a single VHF navigation capable GTN installation with a second non-Garmin aviation unit.

2.1.3 NAV Antenna Cable Diplexer

GTN 650Xi/750Xi navigation units have a single navigation antenna port and require a composite signal for installations that include separate VOR/LOC and G/S antennas. The navigation diplexer (Comant diplexer VOR/GS, Model CI-507) is used for these installations.

3.2 GTN Xi Configuration Mode Overview

NOTE

When configuring the GTN Xi, ensure that configuration module service messages are not displayed in the message queue. This indicates an improperly wired or damaged configuration module.

Configuration mode is used to configure the GTN Xi settings for each specific installation. To access Configuration mode, perform the following steps:

1. Remove power from the GTN Xi by opening the circuit breaker.

2. Press and hold the HOME key and re-apply power to the GTN Xi.

3. Release the HOME key when the display activates and “Garmin” appears fully lit on the screen.

The Configuration mode home page is the first page displayed. For detailed information regarding how to configure the GTN Xi, refer to GTN Xi Part 23 AML STC Installation Manual. While in Configuration mode, select pages by touching the desired key on the display. Some pages may require page scrolling to view all of the information and keys. Scrolling is done by touching the screen and dragging the page in the desired direction or by touching the Up or Down keys.

NOTE

The configuration pages shown reflect main software version 20.00. Some differences in operation may be observed when comparing information in this manual to later software versions.

3.2.1 Updates

The GTN Xi comes pre-loaded with software. However, to make sure it is loaded with the software that is applicable to this STC, a GTN Xi Software Loader Card must be created. For dual GTN Xi installations, the software loading procedures in Section 3.2.1.2 must be carried out on each GTN Xi; however, the same GTN Xi Software Loader Card created in Section 3.2.1.1 may be used.

NOTE

Prior to installing a version of the GTN Xi main board software that is older than the currently installed version, all RS-232 and ARINC 429 ports should be configured Off.

NOTE

Screen shots in this section are provided for reference only. Refer to Equipment List, GTN Xi Part 23 AML STC for actual GTN Xi software versions.

3.2.1.1 GTN Xi Software Loader Card

A GTN Xi Software Loader Card may be created using a GTN Xi Downloadable Software SD Card (P/N 010-01000-00) in conjunction with a GTN xi software application downloaded from the Dealer

Resource Center on Garmin’s website. As an alternative, a pre-programmed software loader card may be

purchased from Garmin. Refer to Equipment List, GTN Xi Part 23 AML STC (P/N 005-00533-L1) for the correct part number of the pre-programmed GTN Xi Software Loader Card.

NOTE

The downloadable application to create the GTN Xi Software Loader Card only runs on Windows PCs (Windows 2000, XP, Vista, Windows 7, and Windows 10 are supported). There is no Mac support at this time.

NOTE

An SD card reader is needed to create the GTN Xi Software Loader Card using the application that is downloaded from Garmin. The approved readers are SanDisk SDDR-999 and SDDR-93, although other SD card readers may work.

CAUTION

It is recommended to use an SD card with capacity of 2 GB or smaller for loading software. If a card larger than 2 GB is used, a version mismatch error will display after files have finished loading. Load software again after cycling power on the unit or the update may be incomplete.
