Your GNS Database
Is Probably Expired.
The OEM service wants $449/year to fix it.
NavCard GPS charges $199.
A plug-and-play USB programmer and NEW proprietary data card system that delivers current FAA NASR navigation data to your GNS unit in minutes. No technical knowledge required.
Why NEW matters
The cards in the eBay market are 20–30 years old — original OEM hardware that physically degrades, cracks, and fails with no warranty. NavCard GPS ships brand-new cards built to current manufacturing standards, with a 60-day warranty on every order.
