According to Garmin Support Memo dated July 21, 2010, effective September 30, 2010, the 28 Volt only versions of the GNS-430/530 series units will no longer be repaired due to parts availability issues.

The 28 Volt only versions of the GNS series units are the very first original productions units from the late 1990s.

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 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.

Negotiating the exchange price of a unit only limits the allowable repair cap for the core unit. Southeast Aerospace's exchange transactions are based on the return of economically repairable core unit. Once the core is received and evaluated, the core repair cost incurred by SEA cannot exceed 75% of the original exchange price. That is, it cannot cost SEA more than 75% of the original OH/SV exchange price collected from the customer. Therefore, when and if an SEA exchange price is discounted, there is a risk that additional charges may be assessed once the core is returned and evaluated.

No, Garmin does not offer an upgrade to incorporate the 16 watt comm. (i.e. "A" version) into the GNS-430/530 and GNS-430W/530W units.
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.

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

Southeast Aerospace does not offer Return To Service paperwork services on General Aviation aircraft for installations that we do not perform.

The Garmin HTAWS or Helicopter Terrain Awareness is only available for Garmin WAAS GPS receivers. The added GPS integrity, quality, and performance that WAAS GPS provides is needed to facilitate the helicopter terrain functions. Therefore, an original GNS430, GNC420, GPS400, GNS530, or GPS-500 navigator must be upgraded to WAAS or "W" status before HTAWS can be incorporated.

No, you cannot directly upgrade a GNS400/500 to HTAWS. You must first upgrade the unit to WAAS before adding HTAWS capability.

The total (approx.) cost to upgrade a GNS400/500 series unit to have HTAWS (WAAS first, then HTAWS) is $15,000 List.
The GNS-430/530 series units can accept information from any traffic advisory system with ARINC 429 transmit formats.
To utilize all of the functions of the GNS-430/430W/530/530W unit, the following items are required:
  • GPS antenna (usually included when system is purchased)
  • External CDI* for VOR/ILS navigation and glideslope information; required for IFR certification as well
  • Nav antenna* for VHF Nav functions
  • COMM antenna* for COMM functions
*These marked items are not included with the standard GNS system. Existing aircraft units may be interfaced however the GNS installation manual should be referenced for complete compatibility information.

As with all avionics installations, other general materials are required for installation but not supplied with the standard system. These materials could include but are not limited to wire, mounting screws, circuit breakers, tie wraps, ring terminals, coaxial cable, hand crimping tools, and crimp positioner/insertion/extraction tools.
Yes, Garmin will still support the discontinued units with the WAAS upgrade; however, units without the upgrade will not be supported.
The Garmin GNS400/500 series units require setup and configuration before proper function and use. The system does not utilize a configuration module to allow easy removal and replacement of units while retaining the programmed configuration information. Therefore, if you are exchanging units in an aircraft, then you must have record of the configuration parameters to reprogram into the replacement unit.
Software Version 1.6 is required on the processor of the Goodrich Skywatch System to interface and display traffic information on the Garmin GNS-430 and GNS-530 GPS/Nav/Comms.
Many avionics systems require a configuration or setup process. This process is required to interface certain avionics systems to other systems in the aircraft that will be inputting or outputting information to and from these systems. Some examples of systems that require a configuration or setup process include:


In addition, most newer technology or solid state systems require configuration via computer interface of some type. A qualified avionics technician should always refer to the appropriate manufacturer's installation manual for complete information and instructions.

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 for more information.

Yes, but please note the following considerations.

For the S-Tec System 20 or 40, these systems are roll axis only. However, if equipped with a GPSS converter, these systems will follow the lateral steering commands from the GPS for a WAAS approach. Vertical guidance is pilot controlled.

For the S-Tec System 30 or 50, these systems are roll axis and altitude hold only. However, with a GPSS converter, these systems will follow the lateral steering commands from the GPS for a WAAS approach. Vertical guidance is pilot controlled.

For the Systems 55, 55X, 60-2, 60PSS, or 65, these systems will track the lateral deviation from the GPS navigator in the Approach (APR) mode and the vertical deviation in the Glideslope (GS) mode. If you are using a 55X or other autopilot systems equipped with a GPSS converter, they will not couple to a WAAS approach in GPSS mode. To follow both the vertical and horizontal deviations of a WAAS approach, the autopilot must be in Approach (APR) mode and Glideslope (GS) mode. The 60PSS system is pitch axis only and will follow the vertical deviation in Glideslope (GS) mode.
The WAAS upgrade for the GNS-400/500 series units is not a 'plug and play' upgrade. There are several installation, certification, and operational subjects that must be adhered to before a proper WAAS upgrade can be completed.

For aircraft with dual GNS-400/500 series units, both units must be upgraded for the crossfill function to operate. A WAAS upgraded 400/500 series unit will not crossfill to a non-WAAS 400/500 series unit.

One subject that many people upgrading to WAAS may overlook involves the GPS navigators distance from the pilot's primary field of view. The original GNS-400/500 series installation guidelines only provided general suggested guidelines for the distance of the unit from the pilot's primary view. Page 2- of the WAAS GNS-400/500 installation instructions is very specific in regards to the suggested guidelines for this distance. The left edge of the GNS unit should be no more than 11.8 inches from the centerline of the pilot's field of view. The 500 series units allow 12.1 inches. Vertically, the top of the GNS unit cannot be lower than the bottom edge of the primary flight instruments. If these measurements are exceeded then an additional annunciator may need to be installed near the pilot's primary field of view.

There are several wiring changes that need to be made to make the Bendix King KAP-140 / KFC-225 autopilots and original Sandel SN3308 EHSI completely compatible with the WAAS upgraded units. Certain features regarding proper navigation deviation will not function properly unless wiring changes are made in the aircraft. In addition, aircraft with more recent glass cockpit technology (e.g. EX5000 and G1000) have not been completely addressed for the WAAS upgrades.

In order to ensure that you receive the most accurate and realistic quotation for this WAAS upgrade, we strongly suggest that you contact our Installation Department for further assistance.

Yes, some are noticeable and some are minor. The WAAS upgrade to the GNS-400/500 series units WAAS upgrade includes a faster 5Htz update rate on the GPS signal. Therefore, the GPS receiver in the unit is extracting GPS information 5 times per second instead of 1 time per second as with original units.

If the terrain advisory feature is installed on the 400/500 series unit, then the terrain information will have a higher resolution.

When the GDL69 datalink is interfaced to the WAAS upgraded units, the weather will cover the entire USA instead of just 250 miles. METARS are included in the waypoint section making it easier to see weather information for a particular destination. Installations using the GDL69A with music will now be able to view the title and artist name on the GNS display.

Lastly, the WAAS upgrade provides the ability to fly curved flight paths with a roll steering autopilot for pilots who wish to utilize DME arcs or full approaches.

The hardware and software upgrade for WAAS to the classic GNS-400/500 series navigators adds FAA TSO C146a Gamma-3 certification. This upgrade and certification enables pilots to fly Lateral-Precision with Vertical guidance approaches and receive GPS navigation via the Wide Area Augmentation System.
The 400/500W units with WAAS capability offer many new features and enhancements over the classic models. Some enhancements include WAAS enable GPS antenna, receiver, and software. The 400W/500W series units comply with WAAS TSO C146a and include hardware upgrades with a faster micro-processor. A terrain database for terrain awareness is included a standard feature. Most importantly, the WAAS GPS receiver allows pilots to use the GNS-400W/500W units for primary navigation and vertical guidance for LPV, L/VNAV, and LNAV+V approaches.

For a complete summary of the feature changes and enhancements, click Here.
There are quite a few changes and issues that need to be addressed in reference to upgrading/modifying a GNS-400/500 series unit to include WAAS capability. It is strongly suggested that you go through an authorized Garmin dealer who has performed this modification/upgrade previously.

There are several installation and certification issues including review of the STC approval from Garmin. This STC includes appendices detailing the approved equipment that can be interfaced to the WAAS capable units as well as approved installation diagrams for these interfaces.

The upgrade from Garmin includes the necessary updating of the unit, WAAS antenna, and new IFR-W Jeppesen database. The existing GPS antenna is replaced with the WAAS antenna. This WAAS antenna utilizes the same mounting holes however it should be noted that it is physically larger than the original GA-56 GPS antenna that was included with all GNS-400/500 series units. Also, in regards to the antenna installation, RG-142B or RG-400 coaxial cable must be used.

As a dealer for an Original Equipment Manufacturer (OEM), it is required to commit to a dealership agreement. Garmin's dealer agreement states that certain TSO'd products must be installed by the dealer for the factory warranty to be valid. There are generally 2 reasons for this policy. First, the OEM wants to minimize their liability risk by assuring their equipment is installed by factory trained and knowledgeable technicians. Second, Garmin wishes to maintain their products integrity by making sure the product is installed and operating properly so the customer is satisfied with the performance. Avionics installations and interfacing can sometimes be very complex. It is very important that pilots, aircraft owners and operators ensure installations are performed by skilled, experienced technical personnel to provide the safest flying environment and experience.
Software Version 1.6 is required on the processor of the Goodrich Skywatch System to interface and display traffic information on the Garmin GNS-430 and GNS-530 GPS/Nav/Comms.
According to the Installation Manual, the following indicators are compatible with main switchable VOR/ILS/GPS Indicator output (Connector P4001) for the Garmin GNS-430 and GNS-530 GPS/Nav/Comms. GI-102 (no longer available), Garmin GI-102A, GI-106 (no longer available), GI-106A, S-Tec ST-180 HSI, King KI-202, KI-206, KI-208A, KI-209A, KI-525A, KPI-552, KPI-552B, KPI-553, KPI-553A, KPI-553B, Collins 331A-3G HSI, 331A-9G HSI, 331A-6P HSI, Bendix IN-831A, Century NSD-360, NSD-360A , NSD-1000 HSI, Sperry/Honeywell RD-550A, 650 HSI. The following indicators are compatible as well but not mentioned in the installation manual: King KNI-520, Collins/STec IND-350, IND-350A, IND-351, IND-351A, 331H-3G Basically, a non-converter type indicator is required for the VOR/ILS/GPS Indicator interface to the GNS-430/530 Note: The following indicators may be interfaced to the secondary VOR/ILS output of the GNS-430/530 (Connector P4006). This output only provides VOR/ILS information on the indicator not GPS deviation information. King KI-203, KI-204, KI-208 KI-209
No. Currently, the GNS-530 does not support an interface for analog or digital weather radar display. Since the GNS-530 is intended to be a multifunction display containing such information as GPS, Nav, Ryan TCAD, and Echoflight , the potential is present. Although the possibility has been addressed by Garmin, they have not released any projected date or timeframe for this interface.
