WAAS Upgrades: Swell But Not Simple
In the world of avionics, we learned long ago that most projects arent nearly as easy and inexpensive as initially anticipated. If your shop or the avionics vendor says, “easy job, no sweat,” count on the invoice being higher than you thought it would be. This is definitely proving to be true with the long-awaited WAAS upgrade for Garmin GNS430 and GNS530 navigators. Make no mistake, the $1500 upgrade Garmin promised entails a major overhaul of these boxes and delivers lots for the money.
