The GNS-430 includes VOR and GS, and the audio panel will have the marker

Since the GNS430 has both GPS and VOR, and will be the primary navigation 
instrument, the real question is this:  Would I rather have a backup GPS, or
a backup VOR?  Or should the stack just include two GNS430s, which would
provide a backup everything?
