PIPER CHOOSES GARMIN!! (Click here for article)
The GNS 430 is the most versatile panel-mounted product GARMIN has produced to date. It combines GPS navigation, VHF communication, and moving map graphics on a big color display. This "all in one box" 12-channel unit offers IFR GPS, ILS, VOR, LOC and glideslope capability in a single, space-saving package. When paired with GARMIN's GMA 340 audio panel and the GTX 320 transponder, this stack of avionics is now reduced to a footprint of only 5 1/2 inches high
Many boxes offer some of the same features as the GNS 430, but it's the integration of so many functions that sets this latest aviation product apart. It will be ready for delivery in early 1999 and is expected to have achieved no fewer than 6 TSO's from the FAA by that time. The GNS 430, which is designed as the first in a line of new aviation products, has plenty of growth potential as it is designed for LAAS and WAAS compatibility.
The GNS 430: combining all the navigation capabilities necessary today with all known and defined technologies of the future
