Due to multiple component availability limitations, comprehensive repair service for Garmin’s GNS 430/530 series, introduced in 1998, is estimated to become limited in the years ahead, according to a March 14 service advisory. This includes all WAAS and non-WAAS GNS 430/530-series GPS navcom and GPS-only avionics.

“Initially, these limitations are estimated to impact a small percentage of repairs beginning in 2024,” said the notice. Garmin will “continue offering repair service when the components required for a specific repair remain available.” Database updates and technical support will also remain available.

The advisory recommends that GNS 430/530 customers “should begin to consider their transition strategy to the newest generation of Garmin in-flight navigation technology, including the GTN Xi series, which offers features like Smart Glide, wireless connectivity, and more.”

Garmin is offering a credit toward the purchase of a GTN Xi-series navigator, GNC 355, or GNX 375 with a qualifying trade-in of a GNS-series navigator. “This trade-in program was launched to assist aircraft owners with their transition from the GNS series to newer generation products,” a spokewoman told AIN.
