I don't understand why GPS navigators (esp. panel mounts) only use GPS
data for navigation. The question is esp. strong in the case of units,
like the Garmin 430/530, which also include a VOR receiver.

Why not have a navigator use multiple sensors?

Some do. But the multisensor units tend to be waaaay more
expensive than a GPS-only nav
