Consequently a CDI is needed. While I am not very familiar with how the 430
works, I also believe you will need a resolver to input VOR radials for the
VHF navigation portion of the 430.

Most Nav radios that have built-in VOR/LOC converters output signals
intended to drive meter movements. There is even an ARINC standard for
these types of signal. (I forget the ARINC number for these analog meter
movement signals.)
There are a lot of older ILS display heads that have the deviation
indicators (CDI/VDI), the flags, and an OBS resolver. I have been able
to pick these up for next to nothing. (I got one free for the asking at
an old shop once.) This type of display may be used with your GPS or nav
with a built-in VOR/LOC converter. No need to buy a brand-new expensive
unit.
