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.
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.
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.
Yes, the Garmin GNS400/500 systems meet RNP5 airspace (BRNAV) requirements of AC 90-96 and in accordance with AC 20-138, and JAA AMJ 20X2 Leaflet 2 Revision 1, provided it is receiving usable navigation information from the GPS receiver.

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.

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.
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.

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
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.
Yes, the Bendix/King KPI-553A can display the distance information output from the Garmin GNS-430 BUT only with the use of the Garmin GAD-42 Adapter. The KPI-553A uses King Serial Data/Clock for its distance information format. The GNS-430 outputs ARINC 429 distance information. The GAD-42 is required with this interface to convert the ARINC 429 Distance Label to the KING Serial Data/Clock Distance information
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.

This output only provides VOR/ILS information on the indicator not GPS deviation information. King KI-203, KI-204, KI-208 KI-209
The Garmin GNS-430 can channel a DME based on the tuned VLOC frequency. The GNS-430 outputs 2x5, BCD or slip parallel DME and King Serial DME channeling formats. There is a setup page in the GNS-430 where you can select which DME you will be channeling with the GNS-430.
The 14/28 Volt version of the GNS-430 units will work on either 14 or 28 volts. The wiring is the same with the only difference being that the 14 volt usage requires a 10 amp breaker instead of a 5 amp breaker on the comm power line.
Yes, the Bendix/King KPI-553A can display the distance information output from the Garmin GNS-430 BUT only with the use of the Garmin GAD-42 Adapter. The KPI-553A uses King Serial Data/Clock for its distance information format. The GNS-430 outputs ARINC 429 distance information. The GAD-42 is required with this interface to convert the ARINC 429 Distance Label to the KING Serial Data/Clock Distance information
