Upgrades Ending for Non-WAAS GNS Series

Garmin has announced the discontinuation of WAAS upgrades for the GNS 400W/500W series. To preserve sufficient parts availability, and to continue supporting GNS 400W/500W-series customers in the future, WAAS upgrades will no longer be offered after May 29, 2020.

Orders for WAAS upgrades MUST be placed by May 29, 2020, and units must be received by Garmin no later than June 30, 2020. Units received for modification after June 30, 2020 will be returned unmodified.

Repairs will continue to be available for the non-WAAS 400/500 series 28v units with 16W COM Transmitter and all 14/28v non WAAS 400/500-series units. These units will not be able to be eligible for the WAAS upgrade after May 29, 2020, but repairs will continue to be available after this date.
