In relation to NE (New) parts, many OEMs change their prices and availability without any notice to dealers or the industry. Therefore, through the REQUEST or RFQ indication, we ask that customers contact us for the most accurate price and availability.

In relation to SV & OH parts, the used parts aftermarket in the aviation industry is not an infinite supply. It is a dynamic, constantly changing market that is significantly affected by and susceptible to highs and lows in supply and demand. Therefore, although we attempt to, at times, we are unable to predict the exact moment when an item may be available. Once again, through the REQUEST or RFQ indication on our website, we ask that customers contact us for the most current and accurate price and availability.

Garmin issued Service Advisory No. 1930 Rev B on August 13, 2020 which stated that repair services and service parts were discontinued for the GPS-155XL, GNC-250XL, and GNC-300XL units.

Garmin has provided Service Advisory 2051 for general recommendations, materials, and supplies to clean and disinfect Garmin products. Otherwise, not following the recommendations could void the warranty.

  • Cleaners containing ammonia will harm the anti-reflective coating on many Garmin aviation display lenses.
  • Disinfectant with a solution of 70% isopropyl alcohol that does not contain ammonia is preferred. Solutions of up to 91% isopropyl alcohol are also acceptable.
  • Clean the display lens using a clean lint-free cloth and a cleaner that is specified as safe for anti-reflective coatings.
  • For other exposed surfaces such as knobs, buttons, and bezels, a damp cloth with soap and water is acceptable.
  • Bleach-based cleaners, ammonia-based cleaners, or other harsh chemicals on any surface are not recommended.
  • Remove all soap/soap residue to prevent buttons and knobs from gumming up or becoming slippery.
  • Many aviation products are not rated as waterproof. Spraying or wetting the units to the extent where moisture could go beyond the exterior surfaces could damage the unit.

Navigation database updates are made available every 28 days. Updates are posted on the www.flygarmin.com website seven days before their effective date. Updates for Obstacle, Safe Taxi, and Airport Directory are available every 56 days; updates are posted on this website seven days before their effective date. Terrain databases are updated on an "as needed" basis, and not on a regular schedule. The FliteCharts database is available for update every 28-days; updates are posted on this website two days before their effective date.

 

Yes, the Bendix/King KI-209A will connect with the Garmin GPS-155XL IFR GPS and the GNC-300XL IFR GPS/Comm to provide Left/Right and To/From Deviation Indications. However, to properly connect the GPS-155XL and GNC-300XL to the KI-209A indicator, the installer must add two 10 kohm, 1/4 watt resistors between the connection. One resistor is placed in between connector P1 pins 35 and 4, and the other resistor between connector P1 pins 37 and 4.
No. The Garmin GNC-300XL IFR GPS/Comm operates on 14VDC from original production. It can be operated in 28VDC aircraft by using the optional voltage converter available at an additional cost. The approximate cost for the converter is $275.

For handheld GPS receivers, database updates can be ordered and downloaded directly through Garmin's Internet site.

For panel mount GPS receivers, all database cards and computer downloads (if applicable) must be ordered through Jeppesen. Contact Jeppesen at www.jeppesen.com for more information.

A normal Annunciator Control Unit (ACU) includes a control and relay assembly. The control portion includes lighted annunciations (words) as well as a switch assembly to activate a relay. The relay assembly provides the electrical transfer of information between a conventional nav (VOR/ILS/GS) and GPS to one Course Deviation Indicator (CDI).

The ACU units can be complete with control and relay built into one assembly or they can be separated depending on the part number. Some GPS systems and CDIs include internal relays. Therefore, only a control with switch is required. In this case, you would only purchase the Control Head. Some installations use different custom sizes and styles of annunciator switches. Therefore, in this case, only a remote relay is purchased without a control assembly.


In addition to variations in switches, relays, and sizes, ACUs are engineered to be compatible with specific GPS systems by different manufacturers. Variations in power input and bezel orientation are available as well.
For IFR GPS approach certification, GPS status annunciations are required to be in the pilot's field of view. These annunciations (or lights) indicate active switches such as the NAV/GPS and OBS (if applicable) modes. Other annunciations or alerts might include the following:

TERM - light that will signal pilot when operating within 30 miles of departure or arrival airport (i.e. Terminal area)
APR - light that signals pilot when the GPS is engaged in Approach mode
MSG - light that signals pilot that the GPS has generated a Message alert that should be viewed on the GPS
WPT - light that signals pilot that the GPS has generated a Waypoint alert that should be viewed on the GPS
INTG - light that will signal pilot when the GPS receiver detects a position error or is unable to calculate the Integrity of the position

Some annunciator units and annunciator control units or ACUs have a variety a these switches and annunciators depending on the GPS system to be interfaced with or the aircraft installation. However, there are certain annunciations such as MSG and WPT that are standard for all annunciators required.

See this PDF document for a detailed listing of currently available IFR GPS systems and a brief comparison.

Newly Overhauled parts obtained from Garmin are designated with an N in their part number. This usually follows the 010- in the part number. As with most Garmin 010 part numbers, the N part numbers are for ordering purposes only and do not actually appear on the dataplate of the unit.
No, the GNC-300XL is not a direct replacement for the GNC-300. Both units have the same dimensions and use the same 37 pin and 26 pin connectors. However, some of the pin designations are different between the 2 systems. Minor rewiring would be required.
