In most cases, Honeywell offers two options for GPS database updates: - Card/cartridge replacement - Computer download

Users can order a subscription and have a database card/cartridge delivered to a given address every 28 days. If an update is not required as frequently, users can simply order a database card or cartridge direct from Honeywell Wingman Services. Click Hereto go to the Wingman website.

The GPS database Internet download option is available for most receivers. The update is downloaded to a laptop computer. The laptop is then interfaced to the GPS inside the aircraft via the PC interface kit (P/N 050-03213-0000). Certain GPS receiver software as well as laptop performance requirements must be met in order to properly utilize Internet downloading and the computer interface. Please view the following document for complete instructions on computer updating. GPS_download.pdf

Please Note: The KLN-35A and KLX-135A GPS units can only be updated via computer as they do not have externally accessible databases.

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 80% of the original SV/OH exchange price billed. Should the Repair Cap exceed 80%, 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 .8 = $800 Maximum Allowable core repair charge or Repair Cap

$2000 Cost to repair core unit
- $800 Less Core repair cap
$1200 Additional billing amount.

2200.00 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.
No. Although they are similar in appearance and function, the KLN-90, KLN-90A, and KLN-90B are not direct replacements for the KLN-88. The KLN-90 series receivers use a different mounting rack, antenna, and larger connector.

While they are not direct replacements, the KLN-90 series GPS systems are the ideal replacement system for the KLN-88. Both the KLN-88 and KLN-90 series units operate through a unique knob functionality.

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 80% of the original exchange price. That is, it cannot cost SEA more than 80% 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.

Yes, this is a total "plug and play" upgrade. The KLN-90B uses the same rack and has the same connector pin-outs as the KLN-90A. The database cartridge style is also the same. The KLN-90B has several upgraded features including certified IFR approach capability, digital OBS and an internal back-up battery pack for continuous operation in the event of aircraft power spikes.
