The VOR portion is an integral part of the 430/530 so I would dispute
that the 430/530's are certified for enroute in a normal certified IFR
installation.

Am I wrong again ?


I don't have direct personal knowledge of this, but I have read in several
places and have been told that the radios are on a separate power supply
from the GPS receiver. I don't know how the display is driven and powered,
if it is independent of the GPS portion.
