Why aren't certain Garmin Avionics products available without installation?
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.



  
What is required to upgrade the Garmin GNS-400/500 series GPS units to include WAAS?
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.





  
What is the difference between the classic Garmin GNS-400/500 GPS/Nav/Comms and the GNS-400W/500W units?
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.



  
What does the WAAS upgrade add to the classic GNS-400/500 series units?
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.



  
Are there any additional benefits added to the GNS-400/500 series units during the WAAS upgrade?
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.





  
What are some of the other issues that need to be addressed when upgrading the GNS-400/500 series to include WAAS capability?
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.





  
How do Garmin GNS-400/500 series part numbers change when upgraded to WAAS?
What factors could be causing a newly installed or replacement avionics unit to not be working properly?
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:

Autopilot
EFIS
GPS
EGPWS
EHSI
RADAR
TAWS
TCAS


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.



  
How does Southeast Aerospace calculate exchange prices and acceptable exchange cores?
Southeast Aerospace exchanges are based on the return of an undamaged, economically repairable core unit with identical part number as the unit shipped to the customer. An "economically repairable" core is defined as one where the cost to repair/overhaul (or Repair Cap) does not exceed 75% of the original SV/OH exchange price billed. Should the Repair Cap exceed 75%, the customer will be billed the additional amount. In the event this amount exceeds the Outright Price for the unit, the customer would only be billed the difference between the Outright Price and SV/OH Exchange Price with the core returned as-is to the customer.

Here is an example of such a transaction:

$1000 Exchange Price charged to customer
$1000 x .75 = $750 Maximum Allowable core repair charge or Repair Cap

$2000 Cost to repair core unit
- $750 Less Core repair cap
---------
$1250 Additional billing amount.

2250.00 Total Cost of transaction

Please Note:
SEA offers exchange on new items as well. However, repair cap as indicated above is still based on SV/OH exchange price.




  
Are SEA's Exchange prices negotiable?
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.

For more information, please refer to these other Exchange FAQs



  
Does the GNS430/530 need to be configured before use?
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.



  
Will my discontinued 28V GNS navigator still be supported by Garmin if it has the WAAS upgrade?
Yes, Garmin will still support the discontinued units with the WAAS upgrade; however, units without the upgrade will not be supported.



  
Does the GNS430/430W have any search-and-rescue functions?
No. Previous Garmin GPS receivers such as the GPS-155 and GPS-155XL included navigation guidance for search-and-rescue (SAR) operations. This allowed users to navigate in a ladder pattern to maximize coverage in an area by referencing 2 anchor waypoints. You could then enter a leg increment value or distance between the legs of the waypoint.

The GNS430/430W does not include this SAR function.



  
What items are needed to install the GNS-430/430W/530/530W systems into my aircraft?
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.



  
What type of traffic systems will interface with and display on the Garmin GNS430/530 series systems?
The GNS-430/530 series units can accept information from any traffic advisory system with ARINC 429 transmit formats.



  
Can I upgrade my GNS400/500 series GPS/Nav/Comm to have HTAWS enablement?
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.



  
Can the original legacy Garmin GNS400/500 units be upgraded to HTAWS?
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.



  
Does Southeast Aerospace provide flight manual supplement and/or FAA Form 337 for systems that we have not installed?
Southeast Aerospace does not offer Return To Service paperwork services on General Aviation aircraft for installations that we do not perform.



  
How can I enable Terrain display on my Garmin GPS-400, GNC-420/420A, or GNS-430/430A unit?
Mod 7, according to Garmin Service Bulletin No.: 0532 Revision B, needs to be performed.

This Service Bulletin (SB No.: 0532 Rev B) describes procedures to perform an alteration to and means to obtain installation and operational approval for use of added TERRAIN functionality. This TERRAIN functionality dos NOT perform the functions of Terrain Awareness and Warning System (TAWS) and does NOT meet the performance requirements established under TSO-C151(), and is not intended to substitute for TAWS.

Approval for unit alteration and operational use of TERRAIN function is by Supplemental Type Certification (STC), SA00800WI (GPS-400), SA00801WI (GNC-420/420A), or SA00705WI (GNS-430/430A), as applicable.



  
I need an affordable IFR GPS system, which one should I purchase?
See this PDF document for a detailed listing of currently available IFR GPS systems and a brief comparison.



  
What is the meaning of the N in some Garmin part numbers?
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.



  
Can the standard GNS-430/530 and GNS-430W/530W units be upgraded to A versions?
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.

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



  
How can the new 14/28 Volt version of the GNS-430 be used in both 14 and 28 Volt aircraft?
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.



  
What DME formats does the Garmin GNS-430 output for DME channeling?
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.

Why aren't certain Garmin Avionics products available without installation?
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.



  
What is required to upgrade the Garmin GNS-400/500 series GPS units to include WAAS?
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.





  
What is the difference between the classic Garmin GNS-400/500 GPS/Nav/Comms and the GNS-400W/500W units?
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.



  
What does the WAAS upgrade add to the classic GNS-400/500 series units?
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.



  
Are there any additional benefits added to the GNS-400/500 series units during the WAAS upgrade?
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.





  
What are some of the other issues that need to be addressed when upgrading the GNS-400/500 series to include WAAS capability?
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.





  
How do Garmin GNS-400/500 series part numbers change when upgraded to WAAS?
What factors could be causing a newly installed or replacement avionics unit to not be working properly?
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:

Autopilot
EFIS
GPS
EGPWS
EHSI
RADAR
TAWS
TCAS


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.



  
How does Southeast Aerospace calculate exchange prices and acceptable exchange cores?
Southeast Aerospace exchanges are based on the return of an undamaged, economically repairable core unit with identical part number as the unit shipped to the customer. An "economically repairable" core is defined as one where the cost to repair/overhaul (or Repair Cap) does not exceed 75% of the original SV/OH exchange price billed. Should the Repair Cap exceed 75%, the customer will be billed the additional amount. In the event this amount exceeds the Outright Price for the unit, the customer would only be billed the difference between the Outright Price and SV/OH Exchange Price with the core returned as-is to the customer.

Here is an example of such a transaction:

$1000 Exchange Price charged to customer
$1000 x .75 = $750 Maximum Allowable core repair charge or Repair Cap

$2000 Cost to repair core unit
- $750 Less Core repair cap
---------
$1250 Additional billing amount.

2250.00 Total Cost of transaction

Please Note:
SEA offers exchange on new items as well. However, repair cap as indicated above is still based on SV/OH exchange price.




  
Are SEA's Exchange prices negotiable?
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.

For more information, please refer to these other Exchange FAQs



  
Does the GNS430/530 need to be configured before use?
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.



  
Will my discontinued 28V GNS navigator still be supported by Garmin if it has the WAAS upgrade?
Yes, Garmin will still support the discontinued units with the WAAS upgrade; however, units without the upgrade will not be supported.



  
Does the GNS430/430W have any search-and-rescue functions?
No. Previous Garmin GPS receivers such as the GPS-155 and GPS-155XL included navigation guidance for search-and-rescue (SAR) operations. This allowed users to navigate in a ladder pattern to maximize coverage in an area by referencing 2 anchor waypoints. You could then enter a leg increment value or distance between the legs of the waypoint.

The GNS430/430W does not include this SAR function.



  
What items are needed to install the GNS-430/430W/530/530W systems into my aircraft?
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.



  
What type of traffic systems will interface with and display on the Garmin GNS430/530 series systems?

Can I upgrade my GNS400/500 series GPS/Nav/Comm to have HTAWS enablement?
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.



  
Can the original legacy Garmin GNS400/500 units be upgraded to HTAWS?
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.



  
Does Southeast Aerospace provide flight manual supplement and/or FAA Form 337 for systems that we have not installed?
Southeast Aerospace does not offer Return To Service paperwork services on General Aviation aircraft for installations that we do not perform.



  
How can I enable Terrain display on my Garmin GPS-400, GNC-420/420A, or GNS-430/430A unit?
Mod 7, according to Garmin Service Bulletin No.: 0532 Revision B, needs to be performed.

This Service Bulletin (SB No.: 0532 Rev B) describes procedures to perform an alteration to and means to obtain installation and operational approval for use of added TERRAIN functionality. This TERRAIN functionality dos NOT perform the functions of Terrain Awareness and Warning System (TAWS) and does NOT meet the performance requirements established under TSO-C151(), and is not intended to substitute for TAWS.

Approval for unit alteration and operational use of TERRAIN function is by Supplemental Type Certification (STC), SA00800WI (GPS-400), SA00801WI (GNC-420/420A), or SA00705WI (GNS-430/430A), as applicable.
