Replace (Fix) ADF?

My '66 Cherokee 180C currently has a T12C ADF. Even though it has analog
tuning, the previous owner installed a Davitron digital frequency
read out so it's not as bad to tune as you'd think.

Anyway, it now longer points to the NDB (actually the needle never moves)
but can successfully tune am radio stations. So my choices a 1 Fix it,
2 Replace it, 3 Remove it.

My plane is currently certified for instrument operation (and I plan
on starting my IFR training shortly). I also have a Garmin 196 (primary)
and a Garmin 195 (backup - came with the plane).

Given the fact that ADF is (someday) being phased up (maybe), what is
the collective wisdom of the group? Which of the three choices
should I pursue?
