up to a 480.

Just a couple of differences. The 480 has airways, the 430 does not.
The 480 allows for user defined holds, the 430 does not. The 480
sequences procedure holds, the 430 "suspends" in holds. The 430 has
easy to use comm/nav knobs for easy access to the radios, the 480 does
not.

The 430 can display XM satellite weather (with a GDL 69 receiver); the 480
cannot.
