Dave,
I had a similar problem, and after much head scratching, found a fix.
Pins H and J on P501 must be jumpered together to get the NAV
to work. I jumpered the pins together inside the KX125 rather than
pull the whole panel out. Whatever is easier for you.
regards,

in the world, from Ron Jones and myself. The story is as follows. Ron and I
are both UK Europa owners, and we each had a KX 125 installed into our Europa
panels by Brien Nelson when he was at RD Aviation. Brien, who now works at
Hinton-in-the-Hedges,
tells me that the problem also affects a third KX 125 that
he installed, but not into a Europa.

When the problem manifested itself during flight testing, I removed the set and
took it back to Alex, who confirmed that there was no fault with the set, and
that it should give a Nav indication.

The VOR indication on the latter is perfect, and the ident signal being picked
up by the KX 125 is in fact stronger than the ident being received through the
430.
